New streamer

Nope. They pretty much invented the space but you can get equal SQ for less $$beand better for more $$.
According to most reviews.

And they are

I’m not familiar with either one. Teac appears to have discontinued the NT - 505 and they have been blowing them out on Walmart for 1200 bucks. Huge step up from the blue bluesound.

It's a streamer / DAC though, not a storage device like the vault.

Had a Aurender A10. Very nice sound but maybe a little polite. If your system is a little dull a Lumin T2 Dac/streamer may be for you. There are so many for sale you should be able to get a good deal on one.
