Speakers are the acoustic Evolution mm micro ones with stands. Preamp is a cheap and cheerful Dared sl2000a (excellent pre!), a rel t7 sub, and I'm running audirvana out to a ressonessence concero USB to spdif... To an old theta chroma 396 non over sampling dac.
I had used the concero as a dac but it was missing a lot of the musical texture and warmth I like. Concero is more neutral and throws a bigger soundstage, but the theta seemed more real. Being fed by the concero, which is excellent at reducing jitter, makes the theta sound really good.
Though that would be the next step to find a better dac, there is a slight, grain in the upper registers, not always noticeable with the Theta.. not on the Concero as DAC
Speaker cables are fantastic, soon to be released by Triode Wire labs.... PC are TWL and Magic mix. I think that's it. I put some nos tubes in the preamp. Sylvanias I believe.
