When I was beginning building my system, I believe I had/auditioned a few amps that I probably couldn't appreciate because my system wasn't good enough. At the time, my speakers were a bad choice the room, I had lousy power, was using random cabling. My listening skills were also pretty meager relative to today.
In fact, just picked up an Octave v110 to see if my original v40se audition was accurate and to gave it another try. I'm fairly confident my current speakers and power setup will allow for a more definitive assessment now. Maybe some powerful push/pull tubes will impart a nice flavor for me?
