What to put under my VAC AMP/ PREAMP??

I am using a pair of Phi 300.1 in balanced mode. I like the triode mode better. My speakers are the ESP Harps. These are 96db efficient. A friend brought over his Bella Extremes which are a fully modded Antique Sound Labs Amps that use V Caps which are Teflon. They are half the power, but seem to be more transparent and more dynamic. He was using Winged C Cryogenic treated 6550 tubes. I don't know if it was do to the tubes or the caps. I know Kevin does not like Teflon. Has anyone else tried these winged c 6550 in there amps.

I think it also has to do with your source. If ones cd dac or phono source is thinner or fuller they may like one mode versus the other. I do like ultralinear too but I get more involved with the music in triode. Its nice to have the choice.

Darin, I prefer triode as you found out. I'm sorry but to get the sound you want you are going to have to get another phi 300.1 and turn them into monoblocks. Place new old stock RCA black base late 50's tubes in the two middle positions and place Sylvania new old stock 6SN7 in the outer positions. Place tube rings on all eight tubes and you will be in heaven. Jeff
