Threshold s150 or Forte 4a amplifier?

Thanks Gundam91, I was wondering how does the Proceed AMP5 compare to the Forte 4A? I heard the 4A's when my dealer was auditioning them in 1994 and they sounded awesome.

I decided to keep the Threshold! I went back and forth between the two. I couldn't decide! After pulling the transformer away from left side on the Threshold.... Ok I have decided to keep the Threshold! The Mod was only Temp. I will have to search for heat sinks and find a good machine shop to fabricate new Top and Bottom. I am going to have the top made from brushed aluminum! I think it will finish out nice! If any one is interested in the Forte Model 4 I just listed it on Audiogon! Thanks Benie and A_rt for you help! A-rt keep spreading the wealth!!!

The brushed aluminum top sound like a good idea it will match the faceplate. I think I will do that as well, my mod was a litte crude (prototype) now that I know this mod is for real it's time to refine it some. I'll keep alook out for some donar heat sinks but as my amp runs cool that can wait a bit I have a piece for the bottom. Maybe I should have kept my mouth shut and bought your S150 as a thought acurred about tri-amping in the future. lol Good luck with the Mod Grizzly.

Contact Jon Soderberg [vintageamp@earthlink.net]. He might be able to help you getting the heat sinks.
He used to work at Threshold and repairs/modify all Threshold/Forte equipment.
He is a great guy and does avery good job. He had worked on my Threshold T2, DAC 1e and a S450e that I had.

Thanks for the info!
