AMPS- - Help ARC 200 or ARC Classic 150 or .....

I used an M-300 MKII, essentially a Classic 150 to drive the top end of my Infinity Betas with great results. Unfortunately, the amps are a little long in the tooth and could begin having reliability problems. After sending one of my M-300s back to ARC twice, I bought a VT100-II.

To amswer your question, the Classic 150s will be "draw you in lucious" sounding, where the VT-100II is a bit more dynamic and detailed. The VT-200 (which I own now) falls somewhere in between. I haven't had any problems with the VT-200, but every now and then I miss the lush triode sound of the C-150.

Rwd,
My VT-200 is the original with a tubed input stage. The Mark II has an FET input stage (I think). The VT-100_II which I owned previously was also a tube input stage. Rcprince is correct, the Classic 150 has a solid state input stage, but they still sounded wonderful with my Infinitys. I think it had more to do with the transformer coupling and high impedance output and less to do with the solid state input stage. If I were purchasing an amp for the Infinity panels, I'd choose the VT-200 over the Classic 150 or VT-100-II. Just my preference. It would be great fun trying them all!!!
