Preamps

ricred1, 4425,

I just contacted Audio Research about your statement that the ARC preamps having issues with subwoofers, and they said there would be no problem.
Where did you get that info?

Thanks for the information. But since the subs are self powered I don't see how the preamp output impedance can affect the sub. Also, the JL subs have a mic/calibration system, that would seem to me it would compensate for any possible low bass rolloff. Now, if having the sub connected affected the performance of the main amps then I would be concerned.

It was very hard to find on the AR website but this is the link. Odd though that the AR rep didn’t know this...
This also kills my plans for using a tube preamp.

4425,

What preamp did you buy?

Is Ayre out of business? Every time I try to call, NO-ONE answers the phone! Its all voice mail!
