Provided that you subscibe to the theory of it being worthwhile. There are a great many Audio engineers who don't rate bi-wiring or bi-amping and will bore you to tears explaining why. I personally think that Rotel have the right idea by offering a 5 channel amp that can decode extra speakers if the power amp is fitted. The same power amp could alternatively be used to bi-amp- again if you think it is worthwhile.
If you want to you can still Bi-Amp with the 6100 or the others I mentioned, In exactly the same way I currently do, I have been toying with the idea of upgrading my 5300 to a 7400 as I would like PL IIx, but am broke at the moment and am not interested unless I can get a decent gain in stereo.
The 7400 although on paper is only a little more powerful in Watt terms tahn the 5400(OSE), in current terms it should be capable of delivering much more, I would also suspect the chipsets are better.
Tried to do a PM reply to your last pm but keep getting an reeor?
Tons - Do you think the SR7400 is a worthwhile step up from the SR5300 in Stereo terms taking into consideration I Bi-Amp with MY 5300 and MA6100's, I would like PLIIx but can not justify an amp change on that alone.
By the way I went for the 6000ki in the end should be here any day now.
