Need a preamp?

But he needs a couple of inputs, and his amp is single ended.
But nice to know the  Nobsound Mini use a proper quad Alps 27 for the xlr instead of wiring pseudo xlr.

@ jaferd,I used to own a passive preamp (Promitheus Reference C-Core TVC) driving my ProAc D48R and the sound was very transparent. But I changed that to a tubed Backert Labs Rhumba 1.3 and I am rediscovering my music again. Those ProAcs of yours deserve something really good. You will be amazed with the music they make with an active preamp. The Backert Labs does not sound "syrupy", which is what I used to think tubes sounded. It is my first "tubed component".
And yes, @atmasphere was one of the a'goner who suggested that I try a tube. Can't believe I listened to him and moved from a TVC to active :-)

Hi Milpai,

Interesting since any active preamp would seem to add some colouration. Did you have a ss amp with the Blackert? Maybe the tube preamp and ss amp was the right combo. I am currently running the st70 in triode and I do like that sound more than in linear and also with my McCormack. 

The Nobsound doesn’t mention if the two balanced and RCA inputs and/or outputs can be used at the same time. I suspect not. It appears to be just a volume controller for a single source.

That's a matter of intense debate. Many think that no preamp has its own colorations too (of which I mentioned earlier).
