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.

Hello and thanks for the replies so far. I did spot the old postings which refer to Parts Connexion upgrades, but the posts were fairly old and I thought I might put it out there again.
I'm definitely leaning toward a tube upgrade. PCX has recommended JJ Tesla KT-88's and NOS Siemens gold pin 6922s.
Upgrading to a Power 2 is an interesting idea, but if the upgrade provides nothing besides extra power, it wouldn't be for me, since the Power 1 has ample power for my system.

More responses are still encouraged.

Thanks
