Ditto Facten on the SQ-88, it has remote control for the volume as well. Sounds great and great build quality. Down the road, you will find it able to drive other considerations in speakers as well. The amps you have named I have not heard, some I have looked into. IMO the SQ-88 has more heft and for myself, a real pride of ownership.
Looking for a first Tube Amp for under $1000
What would you turn to? I've read some very positive comments on the Onix SP3, Jolida JD-502b and the ASL AQ1003DT. What would be a good first amp which is easy to use (setting bias)? I mainly listen to rock and jazz and the amp would originally be played through a pair of Bose 301-IV speakers.
