Damping Factor of Muscal Fidelity A3cr

Not sure, but its gotta be good to rate a Class A from Stereophile. You might check the spec sheet on Audio Advisor (www.audioadvisor.com). Not sure if they have the info you're looking for, but I know they sell the amp.

Just had another thought, if Stereophile rated the amp, that means they did an article on it. You might check your old issues. Well, I assume you get Stereophile, you might not. Try the Stereophile website to search for the article. I was always curious about this amp myself. Looks well made, but seems very affordable. Good luck in your search.

You could possibly email Musical Fidelity and ask them. Also, I saw a post on this site earlier today and now I lost it. Somebody was complaining that their A3cr just quit working after about 3 months and they had to send it back to Audio Advisor. You might try and find that one, if you are concerned about quality--I say this as I strap tape to the box of my 4B-ST that is soon to travel back to Bryston for a overheating problem. Oh well, you can't expect every amp they make to be perfect--but it soon will be perfect. :)
