Calling all Sonic Frontiers "Power" amp users...


I have the Sonic Frontiers Power 1 amp. I want to get some feedback from other users about....

1) Has anyone had their unit upgraded by Chris Johnson (former head of SF) at Parts Connexion? Was it a good, easily noticable, upgrade?

2) I still run my Power 1 with Svetlana 6550C tubes. What do you run? How do you like it?

3) My input tubes are still the Sovtek 6922s that came with the Power 1. Has anyone upgraded the input tubes?

Thanks in advance.

I have not changed the tube compliment that is suggested for the amp...I also have the Line 1 used in conjunction with the Power 1. I would like to here anyone's experiences with other tubes....especially the Parts Connexion suggestion of KT-88s. I am very happy with the current performance...detail and involvement.....my only question is if midrange richness can be enhanced.
