Shuffled My Power Amps around on my Audio system.

I have four amps running my audio system. It's a combo of 2 channel music and HT. I have a Bryston 2.5 sst2 amp for my Aerial 5T's, Forte 6 for my Aerial CC-3 center and a pair of modified Threshold T-50's for my Aerial 5's rear speakers. Preamp is the Luxman CL38U SE. I used the Bryston for convenience as I could flip the switch on the back of the amp for balanced and single ended connections. Balanced went to my Krell Showcase HT processor and RCA to the Luxman. I've been watching less movies over the last few years because of poor quality of acting, and story content. Unless your into super heroes and having your subs bounce over the floor not much. Also too much politics. They really had to sneak in global warming into Aquaman. Anyway yesterday I added the T-50's to my Luxman and Aerial 5T's. The Bryston is a good amp but the Thresholds are on a different level. Smooth presentation; tighter bass and the clarity is like taking the blanket covering the sound. One thing that stood out was the star drum. The wood sticks hitting the drum skins was very realistic. I purchased these amps years ago from a former employee of Threshold. They are not off the shelf amps. He had Michael Bladelius modify them into Monoblocks. The original amp had 8 IGBT output transistors these have 20. Also the balanced circuit was taken out to help it run cooler. It takes about 20-30 minutes for the system to smooth out. No way will I keep these on all the time. Heat and the ELECTRIC BILL. I'm sure if Aquaman new I was running Class A amps he would blame me for Global Warming.
