HD Sattelite Reciever and analog preamp

You can get the C46 Pre amp and find a used MSD4 processor from McIntosh. Or you may look into the MX119, MX135 or a used MX134 to do the job. If you want a receiver the MHT200
that would keep you in McIntosh.

So does your Mc have six analog inputs to pass thru? If so you can pick up a used MSD4 or a MAC3 on Audiogon or AudioClassics.com for a good price they both are good units. I am not aware of any other stand alone processors.
What Mc piece do you have?

Maril555, that is indeed a very nice pre-amp. I have the MX135 which is built on that chassis as a base plus the processing. I would try for the MSD4 if you can find one they would work together nicely. Check with audioclassics.com,I bought one there a few years ago used and it was in excellent shape.
