I preferred KT88's in the SF Power 2 over 6550's. The 6550's might have been more neutral, but the SFP2 is inherently quite neutral and benefited IMHO from the hint of warmth of KT88. YMMV.
EH 6550s or Svetlana 6550C
I currently use KT88s in SF Power 2, but want to listen to some 6550s. I can easily get my hands on either the Electro Harmonix of Svetlanas so am interested in which of the two people recommend.
The rest of my system is:
SF Power 2 amp
Philly Audio 7B pre
RAW Acoustics HT3 speakers
REL Strata III subwoofer
Shanling T-100 CDP
I listen to almost everything, but lately have been concentrating on acoustical blues and newgrass
