When I first got into this hobby on a serious level, I always ran an ARC tube preamp - SP6, SP10, SP11 with a Threshold Solid State Class A biased power amp - 400A, SA4e, SA12e x2 - and I never really incurred any issues regarding channel balance, etc. Things were so much simpler back then and matched dual triodes were much much cheaper ;-).
Your tube preamp and ss amp thread
Last night I was listening to my tube preamp and my tube mono blocks, noticed an imbalance in the sound, and as usual I traced it to a tube problem in the mono blocks. Luckily, I also own a ss stereo amp as a 'backup'. IME, ss amps tend to be a lot more reliable than tube amps. Nonetheless, I would be interested in how many other folk run a tube preamp and ss amp combo, and if so, what are your choices.
