I had a Forte 4A for many years. It's a lot more powerful than the specs indicate. I hooked up the amp w/a pair of Thiel 2.3 floor standing speakers and it smoothed out the top end of the speakers but still had plenty of detail. Only drawback the amp uses IGBT transistors which are no longer in production. Also the people that designed the 4A are the current owners at CODA. The 5.5 50 wpc Class A amp is very similar to the old Forte. You might want to check it out.
Forte 4A vs. Belles 350A vs. Belles 350A Reference
So I'm thinking about a changing my power amp. I'm looking at the three amps mentioned in the title. For those with knowledge of these amps would you go with the Nelson Pass Forte or the David Belles 350A or 350A reference. I appreciate all feedback. My system is irrelevant to the conversation. I'm looking for feedback from those who have owned these amps and are familiar with them. Thanks!
