GMA Europa owners, what amps do you use?

When compared to the solid state Odyssey amp, I don't think the tube amp drives the Europas as well as I would like. I am beginning to think that the Europas want a lot of current and quick power during high transients (like loud drum beats). I was wondering if anyone has had similar experiences since most of these system matching issues are trial and error.

Alot of it also is going to be personal preference. If you prefer mellow, middle of the hall presentations then the tube sound may be your thing. After comparing them for a while, I am beginning to think I like the front row, reach out and touch the individual musicians type of experience.

Will do Roy. Right now I am auditioning a pair of Khartago mono's from Odyssey Audio. Here are the specs:

150 watts into 8 Ohms class A/AB
300+ VA single toroidal transformer per channel
120,000 uF capacitance
>100 amps current RMS
Damping Factor >800 continuous @ 8 ohms

These amps sound nice with just a few weeks on them. They really can deliver power when needed. I became a little suspicious of my present tube amp (45 watt) when I started listening to more rock than soft jazz. Plus, I am going to move my setup from a 16'x12' room with 8' ceilings to a 18'x24' room with 11' ceilings and listening at around 10' away. I think I will need more power than the tubes could provide. The Europas still sound great. Still the best deal in speakers around.
