Without going into a huge amount of detail, his view was that if you were to consider a bi-amp set-up with two D250's vs a D800 dual mono, then the D800 would almost certainly be best. The reason is that the dual mono set up is not just about power, but the different configuration of dual mono versus a single stereo set up offers a number of other other improvements, not least lower distortion. So his view was that in most cases the SQ deficit of going away from dual mono would not be made up for by the benefits of a bi-amp set up. He then mentioned that you could of course bi-amp with two D800's, OK, I get the point, but that is a rather complex arrangement, not to mention very pricey.
I can add my own opinion also. There are two basic ways of bi-amping. One is to keep your speakers crossover, and simply connect two amps to the bass / mid + treble terminals as appropriate. This affords some benefit. Another way is to remove / bypass the speakers crossover (or at least some of it for three way designs) and mimic the characteristics of the crossover electronically with custom high and low pass filters. This has the potential to be far superior to simple bi-amping with the crossovers in place. However, it would be very difficult to get absolutely right, so unless you are prepared to put a massive amount of skill and effort into this, probably best to stick with dual mono and enjoy the tunes!
Hello, Confused. A bit off topic - then even I am having a pair of loudspeakers which are very easy to drive, the SQ will be much improved if I go from stereo to mono (like D200 to D400)? 1 + 1 greater than 2?
I am using D200 to drive a pair of Vivid V1.5.
