The TEAC UD-701-N was superior to the NT-505.
It had all the advantages of the NT-505 over the Vault but in larger amounts.
But none of the disadvantages. The NT-505 at times sounded bright and at moments glassy. For example, on Hamadoun Toure from Toumani & Sidiki Diabete the kora notes just don’t sound natural. The brightness moderated with time. I wondered whether I would find listening fatiguing in the long run. Note that I have not seen other users complain of this in their comments, which are overwhelmingly positive. (@o_holter indicated burn-in was important for the 505 so that may improve further with time.)
The 701 just sounded right. Engaging, natural, emotive. Timing, rhythm, flow of music just sound right- makes you move. Inviting to listen to even with only one channel. (That’s tough to do!) Musical notes with intensity and weight.
Hard to describe. Just that feeling of ahhhh... like a new experience that feels like coming home.
PS
This is a side note. But an observation that stands out. On Valsa de Uma Cidade from Samba in Seattle, Sete taps out a four count before the band starts playing. You can hear on this Vault and 505. Less distinctly on the Vault than 505, although on both it is less distinct than on 701, on which the taps have more weight and character. My guess (since I did not have the privilege of hearing the live performance) is that the 701 portrays the original timbre of those taps more accurately. Another observation from this track that stands out is Sete’s use of dynamics to convey emotion come across very clearly on the 701. There is some of that with the 505 but it’s there to a larger degree with the 701.
