rel with monoblocks

I have a REL Storm III connected to B&K M200's. My manual said to connect the ground to the preamp, but I found it works better to connect directly to the amp as Jeff says, EXCEPT - I think Jeff meant to say "With one amp you connect the positive and ground leads and with the other only the POSITIVE."

My amps sit about 6' apart, so I rigged up a harness to them, and connect the REL cable to the harness.

This means that if you loose the stereo performance of the speakers as the hook-up combines the two channels. It is amazing how many systems I have seen with Rel's where the owners have done this and do not know it is occuring.

This is the case with the hook-up instruactions immediately above (SMW1950) has the same signal now going to both speakers (whatever signal is just supposed to go to the left speaker has now been mingled with the signal to the right speaker and this combined signal is going to both speakers). So in actuality, he is running a pair of mono speakers with a sound stage that is always centered (outside of the impact of the subwoofer being off-center).

This is simply incorrect. With the red wire connected to the Right amp + post, Yellow to the Left amp + post, and black connected to either L or R - post (or any other ground point in the system) it's not possible to combine L and R channels in your amp. I have mine connected this way and am positive I have not lost stereo out put from my speakers.

One qualification: Fully balanced amps can't necessarily be connected this way.

ok, I understand. Indeed not all amps are the same. I knew fully balanced amps present issues for the Rel (and not all fully balanced amps are the same), and it's apparent your amps do likewise. My amps are mod'd B&K M200's and I have no issues with them. Same for CJ's I ran previously, and the Ayre V3 (which is a fully balanced amp but only required a different ground arrangement) worked fine as well.
