McIntosh MA6900 Sensitive to Power Cords? I have

a JPS AC+ cord I will try on it after break in. It's a new unit with the stock power cord connected now. If the JPS does not work out, I have a less expensive Shunyata Diamondback to try. I'm looking to maintain great low end but yet clear up the high end a bit. To me it seems a little veiled on the high end. I am used to a cleaner top end. I know that Mc's are known for a tube type high end that is not greatly extended but I feel I can improve it with the right pc.

Has anyone tried a non-curent limiting conditioner like the Shunyata Hydra? I have a Hydra 4 that I will enventually plug the Mc into. Also how many hours to break in a new 6900?

When I was auditioning an MA6500 I used it with the stock cord first and almost gave up in the first couple of hours. This was a demo unit and well broken in. Constricted, tiny soundstage, tinny sounding, worse than a cheap receiver.

Switched to a VH Audio (it was either 2 or 4, can't remember) and the sound came alive and I bought the amp.

No idea. I don't recall the sound changed all that much.

The 6900 would need nearly 300 hours to fully settle down IMO. The bass would be the last to sound right. My 6900 went from being bright - veiled - no bass - sounding really good. Maintain a log if you can. This way you don't have to keep guessing. Good luck & enjoy !
