I moved to tubes years ago and never looked back.
However I believe the design is as good as its creator.
I have heard excellent SS products as well as tube or digital.
All designs have their strong and weak points, no question about it. Some, just do it better then others.
My main rig is all tube-based:
Granite Audio preamp, now DODD Audio battery pre.
Consonance Opera Cyber 800 mono blocks amp. modify.
Consonance Ref. 40 phono stage.
Nixon DAC soon to be replaced with Peachtree DECCO modify which also has Scott Nixon's fingers in it (DAC and amp. section).
Consonance Droplet CDP
My second system (which I am in the middle of putting together........wating for mimis M&D speakers) is.........well,
very different:
Red Wine Audio sig.30 amp. (t-amp) which IMO is just awesome. It might not be the best match for minis but wife would not be happy with anything bigger in the badroom.......if I could, Omegas or Zu would be my choice with RWA amp.)
Sonos wireless music system as a source, together with modify MMF7 turntable with Moarch up4 arm, Denon 103R cart. and Creek phono.
And again, Peachtree integrated/DAC .
