Gryphon Antileon vs Antileon Signature

Nico,
My amp is 3 years old and it is a great match with my Extrema loudspeakers. Some may complain about a slight brightness with this combination but I believe the it could be due to two reasons: (1) the amp is not sufficiently warmed up (for me about an hour is sufficient) and (2) the recording may be inherently bright.
For most purposes, I believe the older Antileon should be good enough.

Thanks for the info.
I was thinking that the Antileon was a bit on the dark side for sound, not on the bright side...

Nico,
I believe the Antileon will sound great with most speakers on the market. Forget about the "brightness", "darkness", blah, blah, blah. All these jargon is for people who only care about finding faults with their equipment. The antileon will be one of the best audio equipment you will ever own. I will keep mine for as long as I live unless there is a quantum leap in amplifier design.

I see only 3 little defaults on the Antileon :
- it's getting very hot,
- the gain is a little to high for my use : it's over 30db, and I would have prefered around 25db,
- there is no french distributor, so a technical problem would be difficult to solve without shipping the amp back to the Denmark.

Nico,
regarding French distributors: I bought my Antileon with Audio Concert in Paris. Are you sure they are not distributing anymore Gryphon?
I brought them back my Antileon for a repair (burnt a transistor) 3 years ago, and they did it without any problem without shipping back the amplifier.
Agree it will get very hot...
Regarding the sound: medium is fantastic, tweeter not as extended in the high as on some other amplifiers. At least on my Infinity Epsilon sound was not bright at all as a remember (no the amp is in a box as I live in Japan and don't want to change the power supply to 100V...)
