Anyone listen to the ASL Typhoon DT?

Has anyone any experience with the Antique Sound Labs Typhoon power amp. It puts out 50 watts in linear and 30 watts in triode.
I had a loaner from a dealer before. To my ears, it sounded edgy and lean. I sent it back quickly.
I have a ASL Typhoon power amp, and I like it alot,it did take awhile to break in,I think the edgy and lean,was due to it being a new unit,mine sounds warm and full.
Has anyone tried running KT90 in triode on these?
