Anyone tried EH6550 tubes in a SF Power 2 amp?

A local company has good prices on cryo treated EH6550s and I have been wanting to try some to compare the sound to my KT88s (JJ Teslas)

I won't be able to try them out until mid-January, because I'll be out of town. I've heard a lot a good things about the Electro-Harmonix tubes, so I'm looking forward to the swap out.

The KT88's give a fuller sound with a midbass emphasis. The EH 6550's (non cryoed) are more evenly balanced with more detail on the top end.
