How many amps do you own?

Two, tube mono blocks and a Yamaha as-100 integrated I use as a pre amp. This way all my equipment is used all the time, plus I can isolate any issues by using the integrated amp to test outputs. I have been caught in the past with no way of verifying or isolating problems - one channel bias, noise etc. After 40 years of hi-fi I do value a balance control as well, after years of no tone or balance.

Lets not go there! I think I could come up with totals of most other components I still hold on to and use much quicker. When it comes to speakers, I have a lot. When it comes to amps, it gets embarrassing rather quickly. It reminds me of an old joke. "I like both kinds of music, country AND western"... reword and insert "tube and transistor".

I have 4 in use

(2) NuPrime STA9 running mono
Adcom 3-channel for the center and surrounds
Crwn XLS2500 for the subs

Job 225
Rogue Audio Cronus Magnum II
and my real gem:

Currently, there are about 4 amps, but 2 of them are low dollar temporary amps while I am experimenting with a Forte' model 3. It won't be even close to the original amp when finished, due to having to replace output transistors, power capacitors, and few other parts. At the moment, a Carver A220 is in the system, and has surprised me quite a bit, sounding way better than I expected. Before that, a flurry of inexpensive amps were tried, and even a digital amp that I built. It has become the sub amp, and does very well.
