Tube Amp Suggestions

The Music Reference RM-200 would be an excellent match for your system. It provides in excess of 100 wpc into anything above 4 ohms, and even substantial output into lower impedances. Sonically, it yields a direct, unembellished presentation, with substantial soundstage dimensions, believable imaging, and robust dynamics. Unlike most of its tubular brethren, it can deliver the low end of the audible spectrum with real authority. It is attractive, quiet, and doesn't eat tubes. From time to time it can be found on Audiogon for $1,700-$2,400. Finally, I've heard it with Virgos, and I found that it brought that speaker's substantial attributes to full fruition.

How big is your room? I had a pair of Audio Physic Virgo II's in a 18x24 room with a BAT vk60. It sounded great. You can get the VK60 for around 16-1800 used. If you can go for a vk75 or 75se for a little more, than even better. I think the 75se is around 3600-4000 used.

Good luck

Atma-Sphere M-60s are a great amp with the right speaker and the Virgo II is not one them. The impedance of the Virgos drops too low for the Atma-Spheres and you will start to blow output tubes even at moderate level. I had this set up and to fix the problem I had to get Zero-Impedance boxes which better matched the speaker to the amp. It sounded pretty good. I have found that the near perfect match for the Virgos is Pass amps and current run the Aleph 2s with my Virgos. Vac amps also are good as well at BAT. Good luck.

For a little strech (3995$ list) you could get the ROGUE AUDIO m150 monoblocks new.They got 4 and 8 ohms output taps.
Great product .www.rogueaudio.com
George a happy owner.

Thanks for the suggestions. To answer a couple of questions that have been posed. The virgo's have an 89db sensativity and pose a 4 ohm load. My room is 14'X20'X9'. Anyone had experience with the Rogue Magnum M120 with these speakers.

Thanks Again
