I currently own a pair of Gryphon REF-1 and paired with their Sonata allegro pre. Other sourses are Esoteric XO-1 and B&W N800. The Gryphon Mono's are not overkill, all the reserve power will only give you more height room in the music and they do not need 3-4 hours warming time to sound their best. even on the manual states about 45 mins to reach peak performance. How ever, I do leave the Xo-1 and the Sonata allegro on standby 24-7. The Sonata Allegro is one of the best pre amplifier out there and I have owned a ML 32 and many others alike. With my other sources working with the REF-1, the music is very accurate, not warm or harsh.... only explanation is that it sounds very real and studio like as confirmed by a friend who is also a hi-fi nut and have worked in studio's as sound engineer for 25 years. He have stated my system is the best he has heard, but I just love it because its so musical. If you check out the spec's of the REF-1, you will find that they have more reserve current than even their latest current mono's. Infact, Gryphon still use the REF-1 as we speak. Regards
