If you want bass wamping sound then high power SS is in order. If you want sweet midrange magic with a softer more tubuy bass then the Mac is the ticket. If you want a combination then pick something in the middle. The GPH's will show the colors of the amp.
I auditioned the GPH's with both high power SS and the 275 before buying GPH's and IMO the 275 had a slower more romantic sound to it then SS did.
Btw, I prefer slightly higher power tubes if that helps. I went with a VAC PA100. IMO, the best of both worlds.
P.S. Also tried a VTL ST-150 (in home) and found it too SS sounding for me. Too much power? I dunno.
