No sound

Some weeks ago, out of nowhere i got a loud medium/low tone emanating from my system when I turned it on. I reported it here and it was suggested that the problem could be a faulty tube.  I finally obtained new tubes, installed them, and the tone went a way but so did the audio.  Any ideas about what’s going on?   It’s hart to find competent technicians that will come for home repair.

It’s very interesting to to hear the set effectively without a preamp. The signal is direct from the amp and the DAC to the speakers. The Sys is a passive unit and ostensibly adds nothing to the sound. So the sound is extremely clear but cold. It lacks the pleasing coloration a preamp brings. 
Certain recordings (especially older ones). don’t seem to need the coloration and sound just fine.

It sounds better than it has any right to sound.

Yes it’s amazing.  Especially good on LP’s.

i still think my original preamp does a little better, on sound staging and highs.  
 But the direct transmission is incredibly clean.

Strangely, the SQ with the Sys is improving greatly.  I don’t know if it’s breaking in (I didn’t know a switch could break in) or I’m getting used to it.
