OP, are you based in the U.S.?
TMR has a few used Rogue Stereo 100 amps available today with a money back guarantee, and Carver also offers 30 day trials.
Trying at home yourself would yield the best results if possible.
Compare Bob Carver Black Magic 25 and Rogue Stereo 100?
Can anyone help me decide which tube may sound better, a - Bob Carver Black Magic 25 or Rogue Stereo 100? I will match either/or to :Martin Logan 20i. Carver is new but only 20wpc. Rogue is used but 100wpc. Both are online so no way to audition. Thank you all for suggestions.
