Teac UD-701N with newly-developed ΔΣ discrete DAC

DSD signals are transmitted as is, while PCM signals are transmitted after passing through a ΔΣ modulator and conversion to 1-bit signals.

 

Sounds promising, allows feeding it with DSD data if one prefers to bypass processing and have just D/A conversion.

 

I think I need to get one!

Not very promising at all for a whopping 348,000 yen, their NT-505 turned out to be more like a disappointment with all kinda networking-related issues but not sure if that were just a matter of lousy QC or something?

我試過呢個情況, NT-505內網絡組件毀損需要更換不要等待去大昌修理吧
零件大約2-3K需時大約1個月

As reported by distributor, there are a lot of devices dead on arrival.
He told me often the Ether card is not connect properly to main board or it's defective.

I'll pay the $369 (although I don't feel I should have to pay 100%) plus shipping to fix it.. and then replace it with a dual ak4499 streamer if that ever happens!

 

@wklie are you guys the ODM of UD-701N again? Thank you.

Please get one and let us know what you think. :)))

If you give it thumbs up then I could seriously consider it an option since it is an all-in-one DAC.

Sorry, my bad, I thought I had seen that price tag of €1,400 somewhere.
Thanks for the correct info on the price, but I must say that a price tag of €2,675 still makes it very good value, especially if it is as good as the specs suggest.

It seems obvious that this new design is somehow derived from the research and development department that contributed to the creation of the recent Esoteric hi-end DAC.  There are also similarities about bulk pet technology, which seems to be used only by Teac (Esoteric) and Luxman. Do you know if there's any connection/collaboration ?

Just looked at the spec and it seems that the streamer has been upgraded as well. The NT-505 which I have only does DSD128 over ethernet but DSD512 over USB. The UD-701 does DSD512 over Ethernet. So maybe the USB port has also got an upgrade.

Hope someone gets one and try it with HQPlayer.

just got my 701 today. Right out of the box it sounds very nice - great build quality too.

Maybe the first sighting in the wild!  Great to hear more of your impressions in time, especially vs. other DACs you’ve owned/heard.

This device is now on the Teac EU site slated for availability in 2-3 weeks. Full price looks like €3498.98 which would be about right when factoring in costs over the price in ¥en. 

 

Price is now EUR 3699.

At about 50 hours the 707 continues to improve. The 707 was really good right out of the box. I'm surprised at the sound quality actually based on you get what you pay for thinking.. I've owned a few DACS in the past 2 years and the 707 is right there with all of them and already better than most. These are what I remember in chronological order starting with oldest: PS Audio Direct Stream, Teac NT505, Musical Paradise MP-D2 MK3, Waversa DAC3 MK2(ethernet), COS Engineering D1, Bricasti M3 MDX/ethernet, Cary DMS700 ethernet, Bricasti M1-SE MDX V2.0/ethernet, Eden Acoustics Tomei with built-in DAC (AKM), Rockna Wavelight. Maybe a couple others I forgot. I have 2 systems and had 2 of mentioned DACS usually at the same time.

Based on whats inside of the the 701 I would venture to guess the full "burn-in" would take about 400-500 hours. I had been waiting for its release for almost a year, but Black Friday came and I ve bought the 1704 BB  based SMSL D3, but still considering getting the 701. Would appreciate your detailed updates in the future! Thanks!
