Fantastic! Most curious...do you know WHY the person prefers the Evo sound to the Mephisto? Thanks!
I would not like to misquote him unintentionally,but i would direct you to Soundstage Ultra's review of the EVO which reached a similar conclusion.
I owned both Antileon Signature and Mephisto with Wilson Alexia and Magico Q3 speakers. I also heard EVO many times. Antileon and Mephisto are two different perspective on sound. They are both great products but the choice depends on your tastes and rest of the gear.
Antileon line sounds warmer, darker, more musical with bigger stage than Mephisto. Mephisto sounds more transparent with better bass grip and more detail on higher frequencies with realistic stage size.
In contract Antileon has a tendency to round the high frequencies and soften the deep bas but that is not a fault, that's a conscious design choice. I'll come to that.
Antileon line is romantic. Mephisto is a realist.
Antileon can replace a valve amp easily. Mephisto can compete with the best solid states such as Boulder and Soulution on resolution and speed.
To give an example, being a past owner of both, with Alexia I would choose Mephisto without thinking. The bass will tighten up with maximum resolution and Wilson's silk tweeters will sing without a sign of brightness and fatigue.
With my Magico Q3s Mephisto was not really sounding its best. It was great on audiophile recordings but put a less than par recording and you get relatively thin and bright sound with dissatisfactory, too tight, unnatural bass. Antileon line is the perfect choice for Magico Q3 on this case. It will smooth out the potential hardness on Q3s tweeters and blooms the already tight bass. On mid frequencies because Q3 is naturally (world class) crystal clear, Antileon's tubey presentation won't hurt. But if your speaker is already a little bit on the "got the flu" side on mids (I won't name an Italian speaker) Antileon will make the matters worse.
These are all personal conclusions. I am not an expert. Please take these info with caution. Listen to these great amps yourself and decide.
Love and respect.
