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?

@nomorelandings Thanks for notes on TEAC HR streaming app.

@milpai Appreciate pointers to Dutch and Japanese reviews.

@lordmelton Hope to check out Aurender kit. My dealer used to carry their equipment. Not sure if he still does.

I located open box units of both NT-505 and UD701-N. Former thanks to Dylan, who was pleasure to deal with, at HiDEF Lifestyle in Red Bank, NJ. Expect to receive both units this weekend.

Plan DAC shootout at HiFi Buys in ATL next week. Will be able to compare TEAC units to HiFi ROSE streamer/DAC, Marantz CD Transport/DAC, Chord Hugo and possibly others,with dCS Bartok as a benchmark. 

Hope to be able to add to observations of nomorelandings then.

Peace.

 

@bosssound ,

Excellent news. Looks like a lot of reading for me in the next few days on this thread. Will be eager to know how the comparison went and what you end up with. Do keep us posted.

Good luck and have fun!

Cheers👍🏼

@bosssound Nice to see you've got a nice audition ahead.

A big positive with the TEACs is that they have 10Mhz, 50 Ohm clock inputs, if you can listen to them with the clocks connected that will make a big difference.

Unfortunately Aurender doesn't give clock inputs until you get up to the N20, $12k.

The TEACs DO NOT however give digital outputs which means you can't connect an outboard DAC. All Aurenders allow this.

Take your time and listen. Best of luck.

Interesting point. I have no experience of the outboard clocks and cannot quantify the improvement vs cost, which is very substantial for big brother Esoteric and dCS. If anyone does have first hand experience, I would be glad to hear your views. I have tried to get the best out off the ud701n with Audioquest power cable and Ethernet cable, plus xlr and vibration mitigation. Whether any of these are beneficial is unknown, but do no harm other than to the wallet.

I guess there is no digital out as TEAC judges that the onboard DAC is already the strong point and why would anyone buy the product for its streamer section alone? In saying that, I have a Node130 solely for radio paradise MQA stream output via coax.

Hope you enjoy the demos, bosssound and look forward to hearing your views. I visited ATL many times as an aviator. Busy, busy busy!

@nomorelandings  Get your tag now. Trust not holding the lives of hundreds in your hands relieves some stress. Curious what filter settings you employed with your NT-505? I I have settled for now on fixed volume (line out) DSD 512 (Upconversion), slow roll off (PCM filter), wide (DSD filter). Also, what's your estimate of burn-in time? I will withhold opinions on sound until I listen further. By the way, I got hold of NT-505 unit with AKM chips, since folks are so enthusiastic about that model.

@big_greg Same questions to you. Peace.
