Argent, no luck on the A3cr Damping Factor. I checked Stereophile's web site with no luck. They had a review on the Nu-Vista 300 amp (no Damping Factor in the review for that amp either). I also checked Audio Advisor with no luck. I found the Musical Fidelity M3 Nu-Vista integrated amp reviewed in my issue of Stereophile (Feb. 2001). Also checked back at the Musical Fidelity web site with no luck. Not sure where else to look, but if I find something I will put in in this thread.
