Can you biamp the Marantz SR7400?

Is it possible to biamp the Marantz SR7400 using the surround backs? Checking the manual it apppears you can only point the source at the multiroom input.

You can't. Had to leave my desk to find the manual to tell you that ;).

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.

Are these the same people that tell us we need a frequency respond range (aka Sony SACD) that only a dog can hear?

Personally, I don't think it can do any harm, particularly if you suspect the woofers are hard to drive and those extra channels are just sitting there unused.

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 chipset’s are better.


Tried to do a PM reply to your last pm but keep getting an reeor? :rotfl:

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.:rolleyes:

By the way I went for the 6000ki in the end should be here any day now.:D
