I didn't know where to post this and didn't want to hijack an existing thread, so I decided to start one.

Recently, a friend of mine was kind enough to pass along a small portion of his considerable knowledge and experience, and in doing so casually threw down a gauntlet: compare a 20+ year old DAC from the late 90’s with my beloved Soulution 560 as well as my recently acquired Mola Mola Tambaqui. I confidently accepted his challenge assuming there was no possible way a DAC that old could compete with modern design, components and performance. I was technically right in couple of areas. But so very, very wrong in so many others. The DAC is question was a Wadia 27ix v3.0.

I’m still fairly new to this hobby and I had never heard of Wadia. It turns out they were one of the very first companies, and almost certainly the best, to focus on digital audio reproduction back in the late 1980's. They remained among the best in the business until the mid-to-late 90's when Wadia began to suffer from poor direction and mismanagement. The meandering continued until they were finally sold in 2000, again in 2011, then for the last time in 2019, after which they were completely liquidated. The Wadia name is now dead and gone, but after the sale(s), some of the engineers responsible for driving many of the innovations at Wadia defected to what is now McIntosh (yep...this one: https://www.mcintoshlabs.com/). A couple others started another company, Exogal, that recently shut it's doors just over a month ago. Quite sad really as many of these folks will go down as some of the best and most pioneering audio engineers ever.

Right. History lesson over. Back in the late 90's, the 27ix DAC + 270SE CD player combo retailed for around 25k (approx. 43k today) and I fully understand why. This DAC is a perfect example of the not-so-subtle differences between "Real-Fi" music reproduction and “Hi-Fi” music representation. I finally understand why so many older audio purists consider many of the old Burr Brown DAC chips like the 63, 1702 and 1704k to be the absolute pinnacle of "ladder" style chip performance. The 27ix has eight 1702 chips that make music sound so incredibly authentic, engaging, life-like, dynamic, musical and supremely addicting. The 27ix just begs you to keep listening. For example, three hours just flew by like 10 minutes. Multiple playlists were devoured. Multiple genres drawn and loosed. And here I sit...typing this diatribe while desperately searching for another vein in which to push the Wadia needle. This is the only headphone system I've ever experienced that has gotten me out of my chair dancing with headphones on. The sound out of this setup is so highly textured, liquid and musical that you could pour it into a glass (as my friend likes to say). It is a legitimate tragedy that whatever voodoo Wadia put in this thing isn't regularly reproduced in modern gear at a reasonable price (none that I've ever heard anyway).

I ultimately chose the 27ix over the $43,000 Soulution 560, despite the 560 wrecking the 27ix in raw performance, resolution and clarity (while also being the better overall DAC in my opinion). The 27ix is just so much more musically engaging and addictive to my ears and makes the 560 sound slightly "dead" by comparison. The Mola Mola Tambaqui wasn't a particularly close rival either, save for the usual "Hi-Fi" tropes of ridiculous levels of detail combined with a digitally manufactured sense of "analog" sound. For the record, the MMT will absolutely give you one of the best digital renditions of "analog" sound you can get at it's price point, but it doesn't sound even remotely as natural, balanced, textured, liquid, engaging or addictive as the 27ix.

If you want to squeeze every last drop of detail and bit of resolution out of music, the 27ix probably isn't for you (though it is still highly resolving when paired with modern high-end gear). On the other hand, if you want your wife to divorce you because you installed a toilet in your listening room so you never have to leave, the 27ix (along with some of the other older Wadia DACs like the 9, 15, 25, 27, 27i, and 931) should be very high on your list. Many of these older Wadias aren't as handicapped as you might think. Quite the opposite actually. Many of them absolutely dunk on the majority of DACs produced today. The words "musically addictive" would be a gross understatement. These DACs are filled with some sort of ruthlessly addictive musical crack that will always leave you "Jonesing" for another hit. You'll think it about it at work. You'll think about it at dinner. You think about it in the shower. You'll make bizarre self-compromises and excuses so you can listen to, "just one more song...". It really is that addicting (it was for me anyway). Try one and let your ears decide. Just be warned - some of these older DACs, especially the Wadia 27ix, could end up shattering your will, right along with your preconceived notions of what a truly great DAC sounds like. You have been warned.

Lastly, for any Abyss AB-1266 Phi TC owners out there, the 27ix did something very similar to the WA33: it gently breathed the soul of music in to TCs. Using the HIFIMAN Susvaras on this setup did unspeakable things to my brain that may or may not have triggered an unscheduled cleaning of both the front and back of my pants.

Thanks for the great write-up buddy! Out of curiosity, what kind of file format does the Wadia play? Can it play 192, 352 or 384 kHz PCM files? Or DSD256/512? I’m asking not to open the debate on high res audio files but unfortunately my offline library already consists of those files 😁

The heyday of Wadia DACs predates hi-res audio, most DACs of that era will only support 44.1/48k and won't even have USB input

Given the age I expect that you at least have to change the capacitors in the PS. As far as I am aware they were a bit prone to overheating due to missing airflow and the voltage regulators being very close to the capacitors.
Even if you find a mint one you‘d have to spend quite some cash for service and probably some tuning of the regs or get some cooling into the chassis.

I never had the pleasure to listen to one but remember the reviews of the 50k+ CD player DAC combo, nice find!

The 27ix supports PCM up to 24/96.

You are absolutely right about the capacitors. It’s a ticking clock and only a matter of time. I have a repair man working on the CD player as we speak (CD tray is stuck, needs lube, service, etc.). Not all that expensive though. The major cost will be changing out the capacitors. I’m dreading the repair bill, but I will gladly pay it for this DAC.

Interestingly, overheating isn’t a problem at all as this model was designed to run 24 x 7. It actually sounds noticeably better after 4 or 5 days of continuous operation.

You are absolutely right. I use a usb to aes converter until my full reclocking setup arrives. Similar to @normie610, I don’t want to start a format war either, but it is clear to me that for the very best and most accurate sound you should always strive to match the original recording - not an altered or upsampled version of it at 44, 48, 88, 96 or 192. So, in theory, I guess that means putting a system together that can play DSD in it’s native format at it’s native bit rate would be the very best you could possibly achieve.


I also learned that the actual recording is everything. I can’t tell you how many 44.1 tracks in my library absolutely destroy 192 simply because they were recorded vastly better. I still tend to buy everything at 192 if I can, but this system is making me question whether or not that is the right approach.

Sadly, you would need to downsample everything with Roon or something else. I would personally suggest doing your own “Pepsi Challenge.” Pick a particularly well recorded track from your library, research and match its original recording speed and bit rate, then compare it with your Hi-Rez file and see which one you prefer. I discovered that I almost universally preferred the original lower res format on older music, and higher res formats on newer music. I have no clue why (advancement of recording technology?!? More digital processing and fu(kery?!?), but it was quite surprising. It’s really starting to make me question if the race for more and more detail is all it’s cracked up to be

This is true. And I believe it’s down to the way it’s recorded and mastered. I have songs in AAC format and they sound really good! But with newer non-mainstream recordings (I’m talking about recordings from smaller labels: TRPTK, Sound Liaison, 2xHD, 2L, and some others on NativeDSD website), I tend to go for the higher res format.

This is absolutely fascinating to me. It begs the inevitable follow up question; what is so different about the recording and mastering processes between eras that resulted in this disparity? One was typically recorded on analog tape and the other direct to digital? Or perhaps I’m over thinking it and it all boils down to personal preference?!?

Regardless, looks like it’s time to consult the Googlizer and learn more about recording and mastering technology.

Yeah it really is quite interesting. To think that Muddy Water’s Folk Singer album was recorded back in 1964 and it has such splendid sonic qualities! The imaging, separation, air and sense of space is incredible. Not to mention the timbre and tonality, they sound so real.

I haven’t even dipped my toe into those yet…but now I’m going to!

This one, right?!?

Wadia is out of business (bought for parts by some buyers). So just know this before buying any Wadia product.

I also don't know why Solution charges so much for BurrBrown 1792 chip dac (should have picked BB1704, which is the superior chip). It's really old stuff and not SOTA. SOTA dacs have all moved to pure FPGA-based decoder or R2R (just MSB actually)

My suggestion is to try actual SOTA digital brands: dCS, Emm Labs, MSB, Linn, Weiss Engineering and Playback Designs.
