Do McIntosh amps work best with McIntosh pres?

I used my Mac amp with a Supratek Chardonnay (wonderful pre). I still own the Chrdonnay but have reason to believe the Mac pre's have a certain synergy with their amps. This sort of completes the whole Mac sound. Yet to hear a Mac CDP in the same system.

If possible, listen before buying. Good luck!

They sound great with a lot of GOOD preamps. 7270 to a C-1 Carver to a tube Cary SLP98P.

Thanks for the replies,they are very helpful.
