Hi-Res DSD MQA Integration To The Max…

I’ve been integrating audio components since…. …. …. never mind….. I’ve been integrating hi-res (HRA, hi-rez, high resolution) audio into my different playback systems since 2000….

I’ve never seen or heard a more advanced integrated Digital Audio Playback (DAP) device than the Pioneer XDP-100R I recently (finally) ordered.

IMG_0026.JPG

On the lower left is the Pioneer XDP-100R, last year’s model. There is now an XDP-300R. When the 100R came on market sometime over a year ago it listed and retailed for right around $699. Since then I found one for $299 new and have it with me pretty much all the time. 

I was very interested in it from the start because it was the only device I knew that play both MQA and DSD masters in a seamless fashion. 

The other device in the photo to the right is my trusted and beloved OPPO HA-2 (since replaced by the HA-2SE at OPPO, still retails for $299). The HA-2 provides the hefty headphone amp, native DSD conversion to analog playback as delivered from XDP, and lots of extra battery to run or charge the XDP from.

I can travel anywhere with *just* the XDP but there are sound reproduction results with the combination of those 2 devices that are very very very hard to beat especially (and almost exclusively today) if you want to hear and travel and hook your home system up to play both native DSD and MQA up to 384k unfolded. 

It delivers native or upsampled 5.6mHz DSD (for PCM tracks including decided MQA) with a quality of sound reproduction I believe is very hard to beat no matter what you use.

~~~~~ THE SHORT VERSION ~~~~~

I’ve written some audiophile friends about the new setup I have. It is portable, it is long term with battery twice over (really more). It perfectly delivers MQA as well as native DSD analog to any output recipient gear you have (headphones, Bluetooth, Line Out to stereo/studio). It has aeons (days, months, years?) of storage onboard for music or video.  

It doesn’t need a computer to play anything. It *is* a computer.

How does it do this? Here’s my answer:

– It’s an Android PDA (personal digital assistant) and digital player running Android 5.1.1 from Google.  This makes it a very usable and convenient multipurpose tablet that fits in your palm and can host all the Google Play apps you might throw at it. 

I’m using Bluemail and Skype mostly cause I don’t want to burden or clutter it (yet). What I’m saying is it can be your browser, email box, music (and video, hint hint), YouTube player, any media streaming or stored onboard all in one. 

It can’t be your cell phone though you can Skype with calls in and out for $6.99/mo. I’ve used Skype to call out to any cell or Skype or landline number for $2.99/mo. for a very long time when I don’t have cell service (which happens a lot on The Big Island).

By relieving my iPhone of the responsibility of being my portable music player (using the same HA-2 via DoP and the Onkyo HF player app) it freed up all the iPhone  storage (a very conservative 32GB total in comparison to XDP’s whopping 432GB) for photos and videos I take with the phone.  Good trade!

– It is an exceptional MQA decoder providing full resolution unfolding Other popular lower cost MQA DACs I’ve had and used like the Meridian Explorer2 are limited to 192k. None of these support DSD either. 

The TIDAL software player alone with no external DAC just gets you to 96K (one unfold) as will presumably other software MQA players.

– It is 100% DoP (DSD over PCM) compatible that allows it to deliver native DSD to an upstream device (in my case the OPPO HA-2) via a short USB wire (see photo).

– It upsamples PCM to DSD up to 5.6 (11.2mbps stereo) with real precision (no rounding errors) and sends this as DoP to the HA-2 as well….

– It hosts the TIDAL app for streaming MQA etc…

– It has a lot of battery depending what resolution you are playing and how much Android app you use concurrently — but — I back this up with the HA-2 which is also a battery charger good for at least 1x XDP charges.

– It has up to 432GB of storage (!) using 2 SD micro flash slots up to 200GB each on top of its internal 32GB memory for the OS, apps, and music etc.  The SD micro flash cards are of course unlimited in number if that’s not enough for you.  They fit on a thumbnail literally to carry.

– It weights about 7oz.  The HA-2 is a bit heavier (battery!).  All fit in the add-on XDP hard zippered case I got that fits anywhere with cables, Zipbuds PRO (check those out online Amazon for around $25 — and their  brand new “26” AptX wireless creation I got through Kickstarter) and other various audio detritus.

~~~~~ CONCLUSION ~~~~~

What I get from these two devices working together is unlimited headroom for amplification (HA-2 provides necessary oompff even though XDP supports up to 16-300oHm headphones) with the most sophisticated PCM sound ever experienced in my humble opinion. It plays native DSD beautifully as well!

The synergy of MQA decoding with DSD upsampling delivered through an analog 1-bit perfect conversion by OPPO’s HA-2 is a level of Sound Quality on the otherwise edgy compressed qualities of PCM I’ve never come close to experiencing. 

I’m saying MQA sounds great but MQA upsampled to DSD sounds better.

The 2 together fit in my jean jack inside pocket.

The XDP can play everything on its on however the DSD in that case is its PCM converted counterpart, the same as all non-native DSD media players and DACs including Korg’s AudioGate, JRiver and the like. These all also support DoP to connect a “real” DSD DAC to like OPPO, Mytek and many many more.

If you are asking: How can I play the full studio authenticated MQA as well as Native DSD from one setup both in my home and on the go and have all the battery and power for rock n’ roll that I need as well as the convenience of a full Android/Google tablet in my hand traveling around, then look no further…..

Onkyo has very a very similar nearly identical product in collaboration called the DP-X1.  There is also an Onkyo Music app that allows you to buy MQA and other downloads online.

Good stuff. Low Price (I got 2 x 200GB San Disk SD flashes for a total of $150 online btw). Very Amazing Sound.

Did I say it plays your videos stored as well in all the popular formats with 720p resolution. I really like its video quality too.

….integration….the secret sauce for MQA and all PCM is hi-res DSD upsampling. XDP can do this with HA-2 attached and the result is not like any CD you ever heard.

5 Of My Personal Favorite HiFi Audio Gadgets Under $500.

NOTE: I’m not a gear reviewer, just a serious listener for my own enjoyment as well as recording artist trying to get the best sounds on my budget for preparing and editing my own music.

I’ve always had the need to buy things that were on the economy side as much as possible. But my needs for high quality in a lot of the things I am most fond of, particularly music never wants to bend to economics.

So over the years I’ve become persistently good at finding the right products in my price ranges that give me the best sound and best operation overall for music. In our world of virtual realities this is true of guitars, computers, software, microphones, DACs, Preamps/Amplifiers, Internet access, speakers and other disparate things never lumped together in the past so intimately.

I have some favorites for listening to good recordings!

Feel free to contact me via my web page if you have questions about anything I wrote about here. The revolving product I have to buy every 3-5 years that is not listed below is the PC notebook I use for computer audio, a huge part of my world. I spend $250 to $400 on these and can always find the high end portable notebook I need (currently 6GB RAM, i5 Intel quad core 2.6gHz, 1TB 7200rpm drive, 3 USB, 1 HDMI, 14″ screen, CD/DVD RW, Win7 Pro x64).

OPPO HA-2  –  $299
While this product has been updated at OPPO by the HA-2SE model at the same price, I have been using the portable HA-2 headphone amplifier, DSD/PCM DAC, iPhone recharger for several years now since its release.

oppo-ha2

It might be easier to describe this beauty in terms of what it doesn’t do as an optimal mobile HRA device (my term), since it has so many interrelated functions. Overall it is the perfect mobile or home device to handle the digital to analog conversion of music on your computer or iPhone/Android and deliver it to either your headphones/earbuds or wired home stereo/studio.

In addition it has a good 4+ hours of battery that will provide DC voltage to your iPhone while traveling in airplanes and the like. It is portable enough to fit in a shirt pocket or banded together (they provide the thick bands…) with your iPhone in a jean jacket.

The HA-2 charges my iPhone 5S at least 1.5 times during travel, so a fully charged iPhone to begin with can play music with the HA-2 handling DSD64 or 128 and any bitrate PCM you throw at it for flights across the mainland or to Hawaii.

The software player I use to handle hi-res audio files I load onto the iPhone is Onkyo’s HF Player. You download the free version first, then upgrade for $9.99 to handle the hi-res which hands DSD audio to the HA-2 using DoP up to DSD128. All PCM and MP3/AAC can be upsampled to DSD in this mode. Nice!  High Precision gives you better signal to noise ratio (i.e., better sound) at a battery use price.

Onkyo’s HF Player app is accessed from the iTunes setup of your iPhone to load the hi-res files (beware this is klunky but can be done). Otherwise it easily finds and plays all your iTunes songs on your iPhone better than the stock Apple music app (reread the upsample to DSD above).

All in all the HA-2 is an incredible value for delivering the highest quality digital audio to your headphones or your home stereo setup. There is both a line out and headphone jack. The analog volume control gives you precise control over gain on the headphone side. I use it this way to feed my preamp too.

Here’s the PDF user guide:

Oh, and it has a patented fast charging AC adapter that recharges the HA-2 in no time.

 

Meridian Explorer2 MQA DAC – $299

This is the product that for me broke the floodgates of what a listener can actually experience with PCM masters, from CD to hi-res DXD at 24/352.8 or 24/384. It was  the first DAC to hit the streets that decoded MQA in lossless PCM master files of any format (WAV, AIF, FLAC, ALAC, etc.).

explorer2

In 2015 I’d been reading about MQA and all the trials and tribulations of its definition and promises for producing digital audio content as artists and producers had at least heard it in their mastering studio, if not necessarily intended (my humor). It was interesting reading to say the least and the more I read the more interest I had in hearing it.

Using the Explorer2 beginning in February 2016, I started hearing masters created by some of the highest regarded studios in the world, including Norway’s 2L. I was familiar with and owned 2L’s early SACD releases and now saw some of those titles released as MQA DXD downloads.

What I then heard was unlike any PCM master I’d listened to before in the natural sounding reproduction of especially acoustic sounds (my favorite kind).

For $299, the listener had a full PCM DAC up to 24/192 with two outputs for headphones as well as line level to a home stereo/studio setup. That price hasn’t changed as I write this.

This portable (very small and weightless) convenient way of hearing excellent quality PCM of any quality recordings can now be attached via its USB connector to any computer and used to decode streaming music from TIDAL at full “unfolded” rates.

So the streaming bitrate is roughly that of a CD (1.411mbps) depending on the master format (FLAC/ALAC are typically <1.0mbps), but the unfolded bit rate can be as hi-res as 24/192k (9.4mbps, upper limit of the Explorer2, not the limit of all MQA DACs).

My one complaint is the finicky USB connection for this DAC. It seems to lose its USB connection to the PC at the slightest movement. No substituted USB cables seem to improve this condition. It is also slightly annoyingly upside down based on the USB connector orientation which leaves the LEDs facing down.

I believed in the authenticity and comfortable enjoyable listening of what I heard as PCM using the Explorer2 so much that I became an MQA Ltd. artist/content partner and with their help converted all my CD and hi-res masters to MQA encoding for others to download or stream.

 

OPPO PM-3 Closed Planar Magnetic Headphones – $399

Prices for headphones are as volatile in ranges as the Dow month to month. What sounds good sometimes works for some, even as studio/industry standards, but either costs at least twice the PM-3 price, or just doesn’t sound as good to others.

What I found with this comfortable setup is a highly unintrusive sounding headphone that shields me from outside noise distractions (I hate those) and is comfortable enough to wear for a few hours at a time. They have a clean alive sound that isn’t biased towards either sizzling highs or thumping bass lines and kick drum samples.

oppo-pm3

OPPO loves good sound as represented by all of their products and these are no exception in a price range many can afford compared to other big names in studio quality headphones.  A single stereo 1/8″ cable comes with this which is convenient for wearing as well.

You can read about planar magnetic approaches to speakers and headphones elsewhere. I like them because of their flat honest sound reproduction abilities.

 

Zipbuds Pro – about $25

I found and ordered these a couple years back on a whim based on price and the description of the product which included reference to a military grade fibers that don’t decompose in the weather and rain (Hawaii weather decomposes everything from cars to houses to electronic gear in no time).

Also descriptions of the care taken to complete the audio quality as well as patented zipper approach to no-tangle were attractive. A (very very good) noise cancelling mic for iPhone use was a coup de gras.  For $25 what the heck (list may be closer to $50 but easy to find online for $25 or so).

zipbudspro

I had hated earbuds forever, but Zipbuds allowed me to recover from that remarkably. Their product description did not even mention solving one crucial factor that has had me rejecting all earbuds since the earliest Apple iPhone set in 2007: They really hurt my ears to wear.

Zipbuds fit your ears at an angle. There is a soft rubberized attachment fitted in the 3 sizes (SML) they include. The angular thing greatly helps both comfort and sound problems. I never take the Zipbuds out because they are starting to hurt my ears. That is remarkable.

There is clearly a left and right for fit and sound (which changes dramatically if they are reversed). While the R/L is not well marked on the Zipbuds themselves you just need the logo on the zipper facing out and you got it right.

I have also found more than subtle differences in SQ based on how firmly the Zipbuds are inserted in my ears. If I want more bass, I simply push them in a little further. Is that design or simply the convenience of fate?

I’ve shared these as gifts with lots of people, strict audiophiles and otherwise. Without exception they have been received with the same enthusiasm as I have for them.  My second or third set came with  a note in the box with the CEO Rob’s phone number saying to call if I wanted.

So I did call Rob one day and had a great conversation with him about hi-res in general. They are working hard to make it feel and sound right for their customers and have been at it a good long time now in Internet years.

For travel and on the go, nothing beats Zipbuds for quality of sound and convenience. I eagerly participated in their 2016 Kickstarter campaign for their new Catalyst product which is not shipping yet (ok, they are late by a month or two so far…).

Catalyst is a very high quality Bluetooth wireless set of balanced (fitted/weighted) earbuds that deploy AptX and AAC for lossless delivery of sound to the listener without wires.  Check it out.

No wires – 16 hrs battery for playtime, lossless sound quality, comfortable fit. Wireless is where I’m headed in every aspect of what I’m doing with electronics.

 

iFi Audio Micro iTube preamp/buffer – $329

Another great product I have is the original version of this product. It refers to itself as the Swiss Army Knife of Audio.

An iTube2 was just released by this highly innovative and nimble company. iFi-Audio.com has some killer products they deliver to audio lovers at great economy worldwide. Everything from portable DSD/PCM DACs to headphone amps to USB filters and special cables.

ifiaudio-itube

Here’s the relatively new setup I now buy into with my ears: Tube preamplifiers are the best staging device for any good solid state amplifier.

I place the iFi-Audio iTube in between my OPPO 103 SACD/DVD/Blu-ray player and the amplifier I am using (currently NAD 906 multichannel). Having used other preamps and AV processors (all solid state) I immediately found the tube result to be a much more natural sounding delivery from the amp to the speakers.

Everything just sounds better but most noticeable was the serious bottom coming through my Monitor Audio Gold Series towers. I can’t get that acoustic upright or electric bass and kick drum to sound any more coincidentally solid and spacious in the room (wood floors and ceilings) any other way. Voices and instruments also lost edges and yes, even shimmered.

Another huge benefit here for the $329 price is that it will allow many who are mistakenly playing DSD as converted PCM in a player such as the OPPO 103 to now correctly configure the OPPO to convert native DSD directly to analog to send to the iTube preamp.

NOTE WITH CAUTION: To do this make sure OPPO is set to play SACD as “DSD” not “PCM” and disable Audio on HDMI. ****** Be sure not to set SACD playback to DSD unless you have volume control through a preamp or other means – Otherwise you can send 100% gain to your amplifier and do some damage to your speakers, ears and maybe more.******

You can read more on this from my post in 2013: Bartender, Give Me A Sandwich.

I typically use the iTube “Digital Antidote” feature that notably reduces ringing and digital distortion.  I typically do not use the 3D Holographic sound feature.
