Dynamic Duo: T+A DAC 200 and Lumin U2 (not the mini)


I just wanted to share my experience shopping for DACs and Streamers.

What I value -- neutral to warm, transparent sound.

What I dislike -- tipped up analytical sound

So I watched and read a number of reviews in search of upgrading from a 2006 ish Welltronics DAC with a tube output stage.  I liked it fine but was confident I was missing out on detail and soundstage and it could not take the latest formats or DSD.  Plus it would be fun to explore as part of this hobby which I've been in for 40+ years. The rest of my system is Roon Nucleus, Ether Regen switch/After Dark Clock, Oppo 205, Aesthetics Mimas, Vandersteen Quatro fed by AQ Robinhood biwire.  My room is 12x16 with speaker on long end.

First up was the DCS Bartok Apex (combined DAC/Streamer) in excess of 20K.  Auditioned at the store and for a weekend at home.  In my system, compared to my DAC, nice, slightly better detail, not particularly engaging to me.  For the money, definitely not worth it for me.  An audiophile acquaintance graciously offered for me to hear the Playback Designs (no built-in streamer) in his home.  I brought my DAC over to compare on his system.  Similar to the Apex, a bit more detail but I was not blown away.  This may be because I'm just not as skilled a listener or I have less acute 60+ hearing as my host who was hearing what he considered big improvements over my DAC.  I should also note that my expectations were to really like the Apex and Playback and I thought going in I was going to pull the trigger on one of these.  However, I came out pretty neutral with a "they're good, but not outstanding" to me kind of feeling.

Hearing a number of raves about the T+A DAC 200 (around 7k), I got a 60 day trial from Upscale.  Wow, what a nice difference!  The DAC was giving me more timbre, some snappiness from acoustic and electric guitar while not being bright or edgy.  Very neutral.  Lots of filter choices to slightly tailor the sound.  More air and space on recordings and deeper soundstage.  I then read that the separate DSD stage was better than the PCM so streamed some DSD recordings, and those sounded even a bit better than the already great sound.  

The Lumin U2 (not the mini around 5K) had nice reviews and could upscale to DSD 256 and output through USB.  That would be a nice feature given that the DSD stage in the T+A appears to be somewhat better.  Have paired the Lumin with T+A upscaling everything to DSD including my library, Qobuz, and even Spotify.  It is very very nice upgrade compared to the Oppo as Roon endpoint with more improvements in space and timber, very natural sounding.  I've also fed the T+A with SACDs from the Oppo using HDMI (an optional input for the T+A.)  Another very nice upgrade, hearing my SACDs like never before.  

DCS, Playback Designs, and T+A all have their specific engineering speak/marketing claims/approach.  I think these are all passionate companies that believe in their approach to great sound.  At the end of the day, their presentation (and they all present a bit differently) may not be your preferred flavor.  My advice is that while differences in these flavors are very subtle, if you expect to be served the same dish every day over the next decade after such a big investment, you better be sure you like the taste!  Having extended audition periods at home for gear is a godsend honestly and reduces the stress in making a decision.

I'm very grateful to have sampled these very nice products and to find one that works well for me at an expensive yet very reasonable price.  Happy hunting out there to everyone and remember to trust your ears and not price, engineering approach or the look of the gear.

Would love to hear others experiences.

@benzman sounds like a nice system.  If it's in your budget, I do recommend the Lumin U2, or you could even try the mini.  Upscale has a 60 day trial, so might be interesting to try.  You could also try your Stealth USB between the Lumin and the DAC 200.  I didn't find a big difference with USB cables myself, it may be the isolation is so good that the differences aren't as important between the Lumin and DAC 200.  Did you find the Stealth was a big improvement?

Enjoy

Hq player seems a little confusing with reports of large delays when upscaling to higher resolutions

The filters you talk about are Sinc-L and similar. You really do not need to use those. I use ASDM7EC-fast and results are superb. Also it depends on how much upsampling you are doing - 128, 256, 512, etc for the FLAC files. I have no issues with 256 DSD, on my fanless PC. But it will depend on the config of your CPU, RAM and graphics processor. PM me if you need any help.

@ready4audio I have just ordered a Lumin U2. Curious as to how long it took to break in. Also, any tips or suggestions on how to get the best out of it? I have read that the optical input is the best.

@dbb, if you've ordered the new non-mini Lumin U2, then the new USB output is recommended as it is a

  • New dedicated “Direct-Coupled” USB digital audio output port

that has some type of advanced isolation.  Sounds great to me and since I'm up converting everything to DSD it's the only output that can do "native" DSD.

If you're talking about the Fibre input, I have not tried that yet but it's on my to do list.  A lot of folks in the forums seem to prefer an expensive ethernet cable vs fibre as the modules on each end of the chain can still induce their own noise.  That said, if you don't have an expensive ethernet cable yet, it may be preferred over a standard cable and you can implement fibre for not a lot of money if your switch has a fibre output.

The U2 sounds good right away but you can assume about 200 hours for it to fully shine I think, though my memory is vague on this.  Enjoy and please report back on your experience and which output you found best.
