I just discovered this new Mac amp, introduced last week, on the company website. It fulfills one of my product wishes discussed several weeks ago, when I asked Ron C for a multichannel HT amp with balanced inputs and more power than the MC206. Thank you, McIntosh!
Some details: The MC207 offers 200 watts at either 8 or 4 ohms x 7 channels. THD and IM are each rated at Mac's usual .005%; s/n ratio is -89 db when A-rated, and -112 below rated output. Input impedance is 20k ohms balanced, 10k ohms unbalanced. Unit weight is 83 lbs. Its three power meters indicate front-channel output levels.
Ron C:
I would welcome your reply to a few questions about this new amp:
First, what are the performance advantages of the MC207's new Motorola power transistors, and are these transistors utilized in any other current Mac amplifiers?
Second, this amp introduces "Dynamic Power Manager" (DPM), a circuit that provides the same rated power at 4 or 8 ohms, apparently akin to an Autoformer but without the cost and weight of same. I'm curious if DPM provides cooler operating temperatures and less stress on the amp under punishing multichannel output conditions. What were the reasons Mac developed this fascinating new circuit?
Third, my dealer doesn't yet know about this amp--could you supply the retail price?
Thank you!
