Matching Pre-Amp to Amp

Heck I'm I being boycotted for the Mac's or is it something else?

I'd hoped for some comments. I've sent my CJs back for repair, but if they find nothing wrong or they are too expensive to fix then off to looking I go.

I'm driving Revel Salon Ultima2s which are really sensitive to amplification (and liked those Mac 601s I couldn't afford Mark L.) supplemented with a pair of Rel subs (each powered by their own amp).

I'm also open to suggestions about CDTransport and/or digital server (using an Oppo now which will no longer be supported). I also have PS Audio transport, Musical Fidelity, and Cambridge (I have different systems in different places and tend to be a hoarder). Currently I tend to use Tidal a bunch, but not for stone cold serious listening.

I could use some HELP/advice out there. This hobby used to be easier when there were limited choices and, as I have mentioned elsewhere I am in the hinterlands with limited opportunities to listen. What I need is $200k and 30 hits of Acid or Mushrooms and a month alone. 

Brains and experience of the Audiogon world please emerge and enlighten. If I'm stupid I can take that too, but please be gracious. 

Please!

Thanks,

Hello Nab2,

I had seen your initial post, but I didn't respond as I have no particular knowledge of how various preamps tend to synergize with McIntosh amps.

I would just suggest, though, that your questions would be seen by a vastly larger audience if you posted them in the regular part of the Forum, rather than in the Insider section.

Also, when you consider alternative preamps I would keep in mind that the 22K input impedance of your amps is too low to be optimal for some tube-based models.

Good luck. Regards,

Thanks for the response. I've been doing some reading based on your comments. I did find this at Stereophile regarding my CJ17LS2: "The output impedance was below a lowish 800 ohms in the midband and above, but rose to 1.6k ohms at 20Hz, due to the presence of a finite-sized output coupling capacitor. The C-J should therefore be used with a power amplifier having an input impedance of at least 22k ohms if the bass is not to sound a little lean." My CJ 18 has an output impedance of 200 ohms. So both should be OK with regard to matching the output of the pre-amps to the input of the amps. I'll move the post for a wider audience. Heck, I almost don't want to given the reaction I've seen here regarding McIntosh.

Thanks again Al.
