The topic of how much power is needed will be debated forever, but the bottom line for me is that I have 3 sets of JBL studio monitors, I have used them for over 20 years, my ears are accustomed to them, and the titanium tweeters reveal high frequency detail that even much more expensive speakers I've tried simply don't deliver IMHO. I'm not buying new speakers, so the change will need to be in the amplifier. I'm not ditching my 300B SE or my KT88 PP, but after listening to a 120 watt per channel amp for several days now I realize I WANT more power. My speakers can handle it, and I also want a low output impedance for solid bass.
I purchased a 24" by 24" 1/8 inch aluminum plate for the top of the chassis, and the sides will be 6" high oak. The amp will have 12 output tubes per channel - 24 output tubes in all. I'll be using the Russian 6H13C (a close equivalent of the 6AS7G). The amp will be huge, but the chassis will allow any future modifications or improvements to be made, and provide ample room for the 24 large output tubes. This will not be a portable amp. If it sounds good it will have a permanent home as my main reference amp. If it sounds just "OK" I'll sell it off on ebay.
I'll post the first draft of a schmetic I modeled in PSIPCE. The simulation results are impressive.
