Gryphon Antileon Sig Mono vs Ref One Mono


Has anyone compared these two mono amps from Gryphon. The Ref Ones were supposed to be the best ever amps from Gryphon and no cost is spared in making them. I wonder how they stack up against their latest Antileon Mono.

I had the Anthileon Stereo and heard the Ref One at a friends place, the Anthileon has a warmer presentaion, the Ref is more precise and linear... I prefered the Anthileon with my Avalons, you should listen the entire system prior making any decision IMHO.

Thanks guys for the responses. I have a pair of ATC SCM 100SL Passive and a pair of SF Extremas, speakers that love high current amps. Yes Kops, I agree with you that the Stereo can drive most speakers on the market. Just need some opinions on the bigger brothers.
Geshi,
I own an Antileon Stereo driving a pair of SF Amati Homage. Those speakers are known to be a difficult load but the amp drives them easily with enormous reserve of power in a fairly big listening room. My only serious criticism on using a Gryphon big amp is the warming time they need to provide their optimum (between three to four hours)
A friend of mine has the mono brothers with similar speakers and I am unable to tell a real sonic diference with my system at home (although he can, in his electricity bill!). Regards

Pedrito,
I am considering both the Antileon Stereo and the Encore. Can you tell the difference (I don't mean minor ones) between these two? I also think that the Monos are overkill.
Pedro your preamp is?

I'm thinking of matching Gr. Antilleon Sig. with SF Amati anniversario some time.
