Thank you for the review, and yes your findings are roughly the same as mine.....both with Buchardt Audio S400 MKIIs and Clayton Shaw Caladan speakers. I do agree that a better dedicated listening room would improve soundstage depth and width, as my current space is not ideal. I too am really surprised how cool the amp runs, I thought it would be much hotter.
I'm now driving it with an Aric Audio Motherlode XL preamp.....this combo is ridiculously good, as I'm sure the SupraTek is. Glad you're enjoying it....and yes, thank you Teajay for bringing the amp to our attention....I never would have know or considered the S5.5 otherwise, as their other amps are just not in my budget
