To Be Determined

Ditching the Digital Disc Player and Embracing the Stream

Issue 137

I do intend to get back to the normal record review format of this column, but I felt compelled this go-around to continue talking about how my DSD-ripping experience has caused me to completely re-evaluate my approach to the playback of streaming music.

We live in a world where LPs seem to be going strong, but spinning digital discs are rapidly becoming obsolete. Most new computers for both personal and professional applications no longer include a CD- or DVD-ROM drive. The world seems to be passing this technology by – even the audio world – and a couple of years ago when my Oppo universal player stopped reading any type of disc, I was pretty much between a rock and a hard place. Oppo had ceased manufacturing the players, and there was very little out there in my comfort zone (under $1,000 USD) that would provide universal disc playback, including SACD and Blu-ray (BD). But most importantly – could another player provide stellar sound quality? I don’t mind buying used equipment, but when it comes to disc players, I’m less enthusiastic. I ended up getting a new Yamaha BDA-1060 ($600), which will play just about any type of digital disc. It seemed like the best combination of “audiophile” features and disc compatibility at a reasonable price.

But after two years of almost daily use, I’m still not completely convinced it’s giving me everything I want, especially in terms of overall sound quality. That criticism is mostly aimed at SACD and BD audio disc playback (I have a huge collection of SACDs, and a growing assortment of music-only Blu-ray discs). Their playback is not always particularly compelling. Even with available features on the Yamaha unit like Pure Direct mode (which bypasses any video circuitry in the playback chain) and CD Mode (which reduces the disc rotation speed by 30 percent, which improves laser read capability and also reduces vibrations; by the way the BDA-1060 weighs less than 10 pounds) it just doesn’t seem particularly robust. Especially when compared to the first and second generation Sony SACD units that once occupied my system, which were pretty much built like tanks but are probably now in a landfill somewhere.

The aspect that I probably find most disconcerting about my current disc playback setup is the DAC complement of the BDA-1060, which includes a single Texas Instruments PCM1795 chipset shared by both channels. That chipset is not exactly the current state-of-the-art in audio playback, and the individual chips sell for a little over $3 each – not exactly what I’d call my current ideal for delivering audiophile-quality sound from any kind of disc, be it CD or SACD. Competent, yes, but ne plus ultra? Hardly.

I’ve previously mentioned that my digital music playback setup currently includes a dual-box server/streamer combo from Euphony Audio, with linear power supplies from PliXiR; my digital-to-analog converter is a very good-sounding and capable PS Audio GainCell DAC. Everything is wired to my home network, and I only need my tablet or Android phone to get playback started. It’s the most elegant setup I’ve ever had the pleasure to enjoy in my audio system, and provides a level of musicality and realism that just boggles me every time I take a listen. The PS Audio DAC utilizes an ESS Sabre 9018 DAC chipset; its level of quality far exceeds that of the Yamaha BDA-1060. When I occasionally listen to a CD, I always play back using a coax digital cable through the PS Audio GainCell DAC. Direct playback to my DAC, of course, is not possible for me with SACD and Blu-ray, and the main reason I was so keen to recently learn how to rip SACDs (see my article in Issue 135).

My assertion that direct-to-DAC playback of high-res discs is not possible isn’t entirely correct; I probably should have qualified that. PS Audio manufactures their own high-end transport and pays the licensing fees to Sony so that the SACD handshake works between their DirectStream series of disc players and DACs. So for a somewhat princely price, you’ll get native DSD output. But if you’re intent on maintaining a more budget-friendly yet audiophile-quality spinning digital disc setup, there are options, especially if you have a player that provides fairly noiseless and stable disc transport (another area in which I find the Yamaha lacking).

A typical HDMI to I2S converter. There are lots of resellers online, and they all seem exactly alike, though I hear that's not the case.

There are adapters that are available from China ($50-100 USD on eBay) that purportedly will allow you to stream the DSD content directly via an I2S connection to your DAC. Whaaat…I2S? I2S and HDMI are related technologies, but not exactly identical, and your disc player has to have an HDMI output with a pin configuration that’s compatible with the I2S adapter box you choose. Reports vary widely as to their effectiveness, and compatibility issues abound. And your DAC has to have an I2S input, but that seems to be predominantly the norm these days. I’ve seriously looked into this, and it appears to me to be fairly hit-or-miss, but those who have gotten it to work seem very impressed with the results. If you’re thinking about heading down this route, I’d really do my homework to try to figure out if the HDMI pin configuration on your setup will likely work. I guess for under a hundred bucks, it might be worth a shot, and the results could be impressive.

The GeerFab D.BOB (Digital BreakOut Box) is one way to extract the high-resolution content from your media.

And there’s also a stand-alone box, the GeerFab D.BOB ($1K USD), which will allow you to stream the content of SACD or BD discs directly to your DAC– but there are limitations. Certain content can only be streamed via HDMI, and depending on the configuration of your player and DAC, compatibility issues may exist. DSD streaming is only possible via a S/PDIF (coax) output, and there are also compatibility issues – my PS Audio unit won’t handle DSD via coax. However, more recent reviews and reports regarding the D.BOB seem to point towards more compatibility possibilities than were originally reported. So, on a budget, maybe you can get this to work, or, well, perhaps not.

The option I’m increasingly moving towards is getting the disc player out of the picture completely. I took major steps in that direction recently when I successfully unlocked the secret to getting SACD content ripped to my music server. And during that sometimes hair-pulling journey, I had something of an epiphany – why not just eliminate the need for a megabuck player or a less-expensive (but probably less-capable) player? That would really simplify the overall process and eliminate a source of highly variable playback quality.

I’ve spent countless hours reading threads on many of the audio forums about ripping, digital file conversion, WAV vs. FLAC, etc., and have done a lot of A/B comparisons between digital formats myself. I’m at the point where I can’t honestly say that I can hear an actual difference between WAV files and uncompressed FLACs ripped from CDs. But I can definitely hear a difference between a CD played natively on my Yamaha player and a ripped, uncompressed FLAC of the same title played back over the Euphony/PS Audio system – the Euphony played FLAC wins every time.

When you look under the hood at the hardware complement of my current system, it’s hard to find an argument in favor of disc playback with the Yamaha BDA-1060. The server/music player half of my Euphony Summus system incorporates an Intel Core i7 processor with 16 GB of RAM, along with a 1 TB Samsung SSD that stores the Euphony OS and my Roon Core. A portion of the extensive complement of RAM is used to create a ramroot memory playback system that copies the file to RAM ahead of playback, eliminating any file latency whatsoever. The streaming half of the Euphony system uses a Core i5 processor, also with 16 GB of RAM, and the Euphony system is capable of native playback of any known file format. Shockingly, one of the most worthwhile improvements to the system has been adding the PliXiR power supplies, which provide a stable operating environment for the Euphony system that the stock PSUs just weren’t capable of.

Listening to all of my recently-ripped native DSD files (which I personally consider to be the finest digital format that’s yet existed) over the Euphony system is a revelation when compared to hearing SACDs played on the Yamaha player. It’s convinced me that the Yamaha unit is heading to the auction block. I won’t be replacing it anytime soon; I’d much rather spend $100 here or there for an external BD drive that will allow me to rip any CD, BD, or DVD’s content to my server. And I have the $10 Sony Blu-ray unit I picked up at Goodwill for ripping the occasional SACD that might come my way.

I’ve lived just north of the metro Atlanta, Georgia area for over thirty years now. My youngest son lives in Knoxville, Tennessee, and my oldest just sold his house and bought a houseboat in Key West. My daughter still lives nearby, but has been talking a lot recently about moving closer to the Atlantic coast, maybe near Savannah or Charleston, South Carolina. Which – should that happen – would leave us with no nearby relatives, and in my wife’s opinion, no reason to be here. She’s pushing for a quasi-gypsy lifestyle that would allow us to travel about, visit the kids wherever they are, and see as many sights as possible before we both keel over. In that vein, I’ve been playing about recently with some reasonably-priced, high-quality equipment that would allow me to enjoy my music library in high-res without being encumbered by a roomful of equipment.

 

The Fiio M-9 portable high-resolution audio player easily converts to a high-quality digital to analog converter.

One of the devices I’ve been playing with for a few weeks is a Fiio M-9 digital audio player. It sells for about $300 USD, and in addition to offering playback of just about any digital file type, it can also be configured as a USB DAC to use with any system. Here’s the kicker: the M-9 uses a pair of AKM AK4490EN DAC chips – one for each channel — and I’ve had it hooked up to my system as a USB DAC for about a week to gauge just how capable I think it is for that purpose. No full-size DAC I currently have in-house offers independent chips for each channel. The AKM chipset is just a couple of notches below their top-of-the-line, and Fiio offers a choice of five different digital filters to customize the sound – which is shockingly good from such a small device played back through my big rig. Despite offering DSD playback, as a USB DAC, it’s currently limited to PCM file playback, but the Fiio people assure me that a firmware update is on the way that will rectify that situation.

The AKM AK4490EN chipset offers a stunning level of performance in the budget-friendly Fiio M-9.

 

Regardless, the AKM chipset is remarkably good-sounding with PCM material of any resolution. I’d even venture to say that it betters my PS Audio DAC in that regard. A few years back, I reviewed the superb Audioengine HD6 powered loudspeakers for Positive Feedback (you can read the review here). They’re about the size of a pair of British mini monitors, and when fed a direct audio signal from any audio source, delivered compellingly good sound. Such that I even went so far as to say that if need be, I could live with them as my only loudspeakers – they’re really that good. So if my wife really does force me to take my show on the road, and Fiio upgrades the M-9 to DSD DAC capability, at least I’ll have the possibility of taking really good high-resolution sound with me, even if on a much smaller scale.

  1. I hope not to ditch my disc player for a very long time. I too have a large collection of SACD’s and CD’s which I spin in my OPPO 205 feeding a Bryston DAC-3 via HDMI. Simple, easy and I know what i’m playing-not what the music website got from the label.
    The model 205 is far better than the models105 and 98 that preceded it. When my transport finally wears out, hopefully OPPO or their successor can replace it which is cheap-currently $125. Alternately, i’ll just buy a good SACD player if I have to.

    1. Ned,

      Different strokes I guess, I’m just at that point where it’s more important to me to invest in the other aspects of my digital playback system, rather than an expensive disc player. I review a lot of reissue vinyl for another website, and still have a decent turntable and analog playback setup, but recently got a really great LP that was a terrible pressing — it was incredibly noisy. Very frustrating, and experiences like that push me more firmly towards an all-digital setup.

      Thanks for reading!

  2. Hey Mr. Gibbs, personally I’ve found your articles very interesting. Many of us are stuck with same problems regarding playback. I went from turntables to CD players and now I use streaming more often than my disc spinner. I used to own a Sony SCD-1, the one that was built like a tank and weighed 60 lbs. Very nice player which I sold back in 2007 and replaced with an Esoteric DV-60 because it could play DVDs, since I have quite a few music DVDs. I sold the DV-60 last fall to a happy buyer since I had changed the laser pick-up the previous year and hadn’t played it much. I have the second-generation PS Audio DAC-Player combo after having owned the first generation. I replaced the Esoteric with my Oppo BDP-95 which was in the living room and not seeing much use (I have a dedicated listening room). I run the Oppo thru the PS DAC via digital (RCA) cable. A few years ago, I sold my Cambridge Audio CXN streamer and replaced it with a Cocktail audio X-50. I like that unit since it has a I2s out that I connect to the PS DAC. The X-50 has a really decent DAC, but through the PS DAC via I2s, it sounds better. Also, the X-50 cannot play CDs but can rip them to an internal or external SSD hard drive. I have a Modwright KWI200 integrated amp which I like a lot, nice power and pretty smooth sounding for a transistor amp, all that playing through a pair of Focal Eutopia Diablos (standmounts) which, even after 5 years, keep amazing me. The Focals are reinforced seamlessly by a pair of REL 528SE subwoofers; Audio nirvana. My wife would like to sell the house and live the RV life since we have a 33’ Winnebago which we use mostly in the winter to settle in an RV park on the Gulf Coast of Florida. We live close to Montreal (just 20 minutes south), and we have had our share of cold winters. This past winter we didn’t go because of COVID (arrrgh!). But I told my wife that I can’t set up my system in the RV so we’re not selling the house. Also, when we first went down south for winter, I told myself: ‘’Man I’m gonna be 5 months without listening to my system…I’m gonna go nuts!’’ So I went and bought a pair of KEF LS50w (wireless) and a small KEF subwoofer, changed all the cables for something a bit better and with my Ipad as a control play my music from my Tidal HiFi subscription. Not like home, but at least it keeps the Blues away. Man, feels like I’m writing a book here. I must say your article got me going. What a nice hobby we have. Cheers and long life.

    1. Pierre,

      I feel your pain. My wife is insisting that we need to sell out house and either move into a condo or go the vagabond lifestyle in a Winnebago-like vehicle, and that would require me to ditch most of my equipment. Nothing will happen for a couple of years, but it could be drastic when it does — we’ll see what happens.

      I like that you’re playing everything through I2S — it’s probably the best digital connection that currently exists, and the least restrictive in terms of getting native file playback to your DAC. Good luck with whatever road you end up heading down!

      Thanks for reading!

      Tom
