Powering Audio Physic Virgos

50 wpc in a smallish room might work. Depends on the amp. I had Virgo's II's (very similar to I's) in a mid sized (18x 16) living room for 3 years with a BAT VK60 tube amp. 60 wpc. Absolutely loved it. Not a single complaint.

If it's a good, high current design, you are likely ok.

While I can't recommend this as a long term solution, a friend had the 1's and used the 45 watt cj tube integrated for a while with fairly satisfactory results.
How big is the room, what are your tastes, in terms of volumes, and what kind of 50 watt amp are you talking about? Without this information nobody can make a resonable comment or suggestion.
Let us know.

Thanks for the comments. The room is about 12x18. The amplifier is a 50 wpc Audio Refinement Complete integrated. The Audio Physic is a 4 ohm speaker, so the amp is actually rated somewhere around 90 wpc at 4 ohms. I listen to all kinds of music, but don't play very lound because I live in an apartment.

Try getting hold of a pair of CJ Premier 12 monoblocs. They work superbly with these speakers!
