2 amps or 1? (1 Viewer)

[Chris Popovich]

Hello all,

I'm looking for a decent external amp to power my B&W 804's. I was thinking about getting two Parasound 2125's and bridging one per channel, or just get one 2250. 250 watts or 400 watts but with less low impedance capability. What are your thoughts on this? My 804's minimum impedance is about 4 ohms, so I think I'd be fine either way. BTW, this was suggested by a dealer, and the price for getting 2 of the smaller amps will actually be almost the same as one of the bigger ones.

Thanks!

When you bridge an amp the signal to noise ratio goes up so I'd say either go dual mono blocks or the larger stereo amp.

I would not argue that when measured with instruments, a bridged amp's S/N ratio goes up (though I haven't heard this for ages), however, when I bridge my $2,800 Citation 7.1 amp for 425 watts X 2 into 4 ohms, noise is absolutely not an issue. Just like with my other amps, if I put my ear right up to the tweeter I can just barely hear a little hiss. At 1 foot, nothing at all.
