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.

i have a Conrad-Johnson tube preamp which is out for repair for an extended time. That’s why I got the Sys, so I could listen to music.  Of course the tubed CJ is much better, but the Sys is a very good stopgap until I get the CJ back.

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.
