TEAC UD-701 vs NT-505 vs ?


I stream Quboz and Tidal via a Bluesound Vault 2. Vault transmits to Parasound JC2 to modded A21 to Vandersteen Quatro CTs. (See my profile for complete description of system.) Happy, really very happy, with Vault 2 but it is likely best point at which to upgrade my system.

Considering TEAC NT-505 ($2K) and new TEAC DAC/streamer UD-701 ($4K), which has some very attractive features: in-house-built discrete Delta-Sigma DAC with FPGA circuity, dual-mono signal path, four separate power supplies... Have seen enthusiastic reviews for NT-505 from owners here. Only one review by Moon Audio out about UD-701, and they are not an uninterested party. Curious if any out there have heard UD-701?

Open to other suggestions, including used with roughly $6K price ceiling. See TMR has used Aurender A-10s for sale. Used PS Audio Direct Wave DAC with bridge is another consideration, although I have seen owners comment negatively about the bridge.

Not wed to DAC/streamer combo but that has appeal to me because it eliminates a box, connecter, and power cord, all of which add to cost and connector makes signal path less direct.

Also not wed to SS but a tube DAC appears to me to introduce an additional source of distortion into my otherwise SS system, so it will then be affected by both SS and tube distortion.

Thoughts?

The build quality is unquestionable, very high level. The fact that they learn and borrow from esoteric makes UD-701N even more attractive. But still, I don't really understand why Stereophile, TAS and other magazines never reviewed a product by TEAC or Esoteric. There are tones of reviews from other DAC/Network Players like Topping, SMSL, Gustard, Denafrips, HoloAudio, Mytek, HIFI Rose but there almost none for TEAC and maybe few for Esoteric. Is it a bad marketing or, magazines are avoiding them for any(?) reason. I just don't get it. 

Concur on the lack of TEAC advertising and reviews...

I was not familiar with nor would have considered TEAC without a recommendation from my local dealer to just give the NT505X a listen, as he and some audio club members did a listening session with it against a well known, much more $ brand  (and its new upgrades) and were impressed, perhaps surprised, that they all preferred the TEAC.  I wasn't really even in the DAC market.  I did a little research (and found this thread...as there are very few on the 505X or the 701N), and thought why not give it a shot.  The 505X was indeed impressive, but glad I am also trying out the 701N.

Honestly, the digital side is secondary to me, but I'm all for major improvements at reasonable cost.  There are many other brands/models to possibly try out that have many reviews and associated advertising, but the TEAC value (relative to either model being discussed) would be hard to beat, I imagine.

Regarding the lack of reviews for Teac, I had read that they do not loan units out for review, not sure if that's true.  Long time UD-501 owner (Burr-Brown chips), very happy with the  unit, fantastic build quality and trouble free.  Smooth rather than hyper detailed, my Mytek Brooklyn+ beats it there, but it's still a keeper.  Lusting for the NT-505 or 701, but financially not feasible.  Miim pro next for sh*ts and giggles as replacement for my PC based streaming.

I completed a long weekend home demo with the UD-701N last week...

so impressed with what I heard (as was my wife) that I went ahead and asked my dealer to order one for me on Tuesday and picked it up yesterday (very fast turnaround).

It's now residing in my system rather comfortably.  Very nice piece of equipment and I feel a great value (as is the NT-505X).

BTW, I'm not real thrilled with the Lumin/TEAC/Esoteric app, but it's usable.  Mconnect is still my go to for control, but that may change if/when I ever do more streaming (other than my local NAS).

Although nothing beats a home demo, this thread here was very useful (and just a few others I found in the interwebs).  Lots of other usual suspects in this price range for Streamer/DACS, but this TEAC fully suits my needs.

I’m a dealer so take this as you will, but I got a demo unit to test on the possibility of picking up the Teac line.   
 

The first thing you notice is the build quality, which for the money is off the charts.  But build quality isn’t sound quality — I hooked it in our reference system and A/Bd it vs a couple of DACs, cheaper and more expensive.   Longer story short, it’s a terrific DAC at its price point and above.  Add in the flawless operation of the streaming (via Roon or its own app), ability to work as a 100% analog preamp for vinyl and many other features, and I think it’s a killer value and an excellent component on an absolute level.   And in a surprise to me anyway, adding the external clock clearly improved audio performance.   Based on this experience, we picked up the line.  I’ll be A/Bing it vs its Esoteric counterpart soon.  
 

From the house designed DAC to the build quality/internals at the price point; the UD 701N reflects what a larger company with the engineering prowess and buying power can do for the money if they put their mind to it.
