Mono-blocking my two Mc Intosh MC-2205's ???


About three years ago, I got a deal on two Mc Intosh MC-2205's from a trusted friend who resides in the suburban area of Chicago (MINT CONDITION!!!).

These amps are extremely heavy and well built to say the least. Since I own two of them , and have yet to hook them up...., I was thinking of bridging/mono-blocking each unit to obtain a 'whooping' 400 watts per channel, to feed my hungry but deliciously sounding Infinity speakers.

Knowing the repretation of these units, and reading the reviews from the archieves, the MC-2205 was a 'kick-butt' amp that was manufactured between 1975-1979. Living up to the Mc Intosh repretation, according to the reviews, they showed no weakness anywhere across its massive power band.

I need to know how to correctly hook/wire each unit to obtain my goal. I don't want to hurt these precious 'solid state' senior citizens.

I have read that mono-blocking is not a good technique? I have also heard that mono-blocking is a poor way to achieve a true 400 watts per side, because there will some wattage loss given the design nature of mono blocking. I've even been told to ditch the old Mac's and go out and purchase a single amp that would meet my 400-500 watts/channel desire. (I don't have deep pockets, so I must work with what I have. I can't afford 5-9K for a new Mac)

I need to learn the proper way to bridge these two amps, so that no harm will come to them..., and if mono-blocking is a great idea? These amps will be feeding a pair of (year 1976) Infinity Concert Series - Quantum Line Source, which can swallow up 500 watts per speaker in a hurry!!

Help please,
