ProAc Response 2 speakers and tube amps?

Since you've had your ProAc's for seven years, what are you using currently and why go tube? The mid & bass drivers are very carefully designed with a shallow voice coil and long pole magnet, they are "long-throw" units. The damping factors inherent in tube amplifier output stages will cause all the investment in the ProAc's to be wasted, as the back-emf from the excursion of the cones will overpower the transformer's ability to drive them; this will create high-order harmonic distortion, so what did you buy the ProAc's for?

Why go tube? Because it sounds better! Better guitars, pianos, horns, a more relaxed non shrill sound, way better midrange. Everyone out there who feels they are missing something in their system, mainly midrange, you only need to add some tubes. And to answer your question.... ARC matches very well with proacs.

I have to agree with Accutronix. Our local Tempe dealer, Arizona Tube Audio, demonstrates the ProAcs on Audio Research tube amps in bi-wire configuration. And, they sound great! He is also a Cary dealer and they sound good on either brand.

the best match amplification for the proac 2 has to be those single ended amps from Audio Note. preferably 300Bs.try them, u wont regret it. thats if u can get your hand on those in your region.
