If you search the archives there are a couple of users that have had the parts connexion mod and they swear by it. I wouldnt doubt it, SF was an ingenious company. I have a power 2 and i am running valve art KT88, sylvania gold pin 5687s and seimens gold pin 6922s. The change in sound is very noticable. The mids are velvetly smooth like a good merlot. and the highs are crystalline without being harsh. Also he KT88 add a lil bit of power (i think about 10-15%), i not sure if that is good or bad for you. All i know is that i love my amp. In fact, i had a power 2 and sold it to buy a BAT VK75 Special Edition, and i prefered that Sonic Frontiers unit, so i sold the BAT and bought another Power 2, i used the left over $ to upgrade to a new pre and buy a nice stand, good tubes, and some cables. Im as close to nirvana as i ever have been
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.
