Budget Preamps for Atmaspheres?

I appreciate the responses, but my problem is that there is no way i can afford to buy an atmasphere and an expensive preamp, so atmasphere preamps and aesthetix are out of the question. I've never used a preamp, so I'm not quite sure how great an effect they can have on the overall sound, but would it be entirely ridiculous to use a cheap Chinese made preamp, like a Dared, or radii, used cayin, etc. or some other budget preamp with a high quality piece like the Atmaspheres? I don't think I would want to spend much more than $600-$700, and really the goal would be to spend as little as possible. Are there any preamps in this price range that show up regularly on Audiogon that would be able to allow the Atmaspheres to show their stuff?

Are many preamps not fully balanced? Sorry, I'm a complete no-nothing when it comes to the technical side of preamps.

My speakers are Soliloquy 8.2s. They were one of the first 2 models produced when Cary/Dennis Had owned the company. They are probably 91db (no documentation available for these), and I'm not sure of the impedance, but I think even the smaller Atmas can run them quite well.

Still debating this, but this thread has helped greatly. Depending on finances over the next few months, I expect to go in this direction.

Thanks for all the responses.
