2x MC-402 vs. Monoblocks
This is a question regarding the long term "road map" for my system. Assuming power hungry speakers at some point down the road, and the fact that I own a McIntosh MC-402 which can also be configured in in parallel/mono at 800 watts, would adding a second MC-402 in this configuration be more effective than upgrading to true monoblocks (say for instance MC-601s)? Are there any disadvantages of this setup versus true monoblocks?
Price/watt and logistics wise it seems to make more sense considering these rough used prices: MC-402 --> $3000-4000 each MC-501 --> ~$6000 MC-601 --> ~$8000 (?) So basically, for similar cost, either configuration is possible, with the 2x MC-402 configuration taking the power crown and having the additional benefit of not having to sell gear. What else should be considered? One thing that I noticed is that the parallel configuration for the MC-402 only supports 1, 2, and 4ohm loads versus a true MC monoblock which supports 8 as well which would limit speaker options. |

Are you sure the MC402 can be run in parallel mono?
Not all MC amps can be run bridged. |

It appears mgbaron is aware of this limitation; I had considered upgrading my MC252 that I had at the time to an MC402 as a subwoofer amp but I ultimately shied away due to the mono parallel/impedance limitation. It my view this was a shortcoming to the MC402. Pete

a 352 can be bridged in real mono I think that is the way I understand

Several years ago when I was considering the same option of adding a second 402 or moving to 501's, I spoke with someone at McItnosh, probably Chuck Hinton and he stated you would get more power out of the two 402's with a very, very slight increase in distortion but unlikely to be noticeable.

It seems that modern speaker designers have settled on 4 ohms as the typical load impedance of newer speakers, so operating a McIntosh MC402 amplifier in parallel mode, where the 8 ohm taps become 4 ohms, would not present a problem providing an owner is driving a 4 ohm speaker load. Being able to operate the MC402 in parallel mode is a nice feature. It is unfortunate that the newer MC452 can only be operated in two channel stereo mode with no provisions for bridged or parallel output.

I also agree Dan that it is unfortunate that the newer MC452 doesn't offer any kind of bridging option. I briefly considered this beauty as a way to upgrade from a single MC501 for more power to my sub. Once again I had to abandon the idea. What a shame. I was unaware of 4 ohms becoming a trend for newer loudspeaker designs...I guess I've just not been paying that much attention to that aspect. I guess maybe I'm just an old fashioned 8 ohm kind of guy! Pete

Pete.......Back in 1968, my Altec Voice of the Theater speakers were 16 ohms, and produce 104dB with 1 watt. Talk about an efficient horn loaded speaker.
At any rate, I think Matt will be fine adding an additional MC402 to his system. 800 watts per channel is a nice place to be with output power, and he doesn't have to sell his existing MC402. I think that's the way I would go if I were in his position.

Thanks for all of the info. It's interesting, despite there being nothing hugely wrong with the configuration, after tons of searching, I haven't actually seen anyone that uses it. It seams like the upgrade path is more typically straight to true monoblocks. Calling McIntosh is probably a good idea before going this route. Also, without the option to go 8 ohm, you'd have to be pretty sure your speakers sounded best on the 4 ohm taps.
