Since the RR2150 has A and B speaker terminals, would it be possible to wire a pair of speakers like you were bi-wiring, only you would be using the A binding posts for the low end and the B posts for the high end? And of course running the receiver in A+B configuration from the front panel?

Of course, I would not try this until I was absolutely sure it would not damage anything.

Any thoughts?

Dntblnk22, this is exactly the way I connected my Adcom GFA535 to my Magneplanar 1.6QR's and it worked perfectly. I think you'll be pleased with the results.

Let us know.

I'm doing the same and have a sub connected to the sub out that appears to run with the "low end" speakers on channel A. The sound is pretty impressive . The only tricky part is using the bass management and potentially the bass eq controls on the front. I'm still playing with the settings, dangerous thing to do, perhaps but fun!

I did the A/B thing with a Cambridge Audio A500/Boston Acoustics Subsat Six. A to the sats, B to the woofer module. Very nice sound.

I'm gonna try it with the RR, if I can tear myself away from the RR/JMLab Chorus 714S combo. This receiver is amazing. The FM shocked me. I was planning on using an outboard tuner, but... maybe not. I listen to a lot of FM.

Is there a real sonic improvement in doing this? How does it affect the amplifier in the RR2150?

When my RR2150 arrives, I'll be driving a pair of Polk LSi9 speakers. A notably difficult to drive, 4 ohm speaker. I guess I am just curious as to how this would affect the amp under a load like that. If there is a notable sonic improvement, then I would be all for it.

Thanks for the replies! Curious to hear your further opinons.

Thanks!

speidi1, I am very happy to hear that the FM tuner section is working well. I also listen to a lot of FM.

I really cannot wait for this receiver to show up. The wait is killing me!

One further question...

If I were to wire my setup in this manner, would I notice any adverse effects if the cable that was connected to the A posts was shorter or longer than the cable that was connected to the B posts?

Dntblnk22: try to stay alive. You're gonna love it.

"Real sonic improvement": hmm. Theoretically biwiring results in reduced interaction between lower and higher frequencies in the wires and that should be beneficial, and it seems to me that the Maggies have sounded a bit cleaner with biwiring, but I really don't know if the difference would show in a blind A/B test, and how would one conduct it anyway? Has anyone read of such a test? Audio listening is so full of expectation, placebo effects, and downright self-BS that objective certainty is very hard to come by. I figure the effects of strong belief in this area are a lot less harmful (except maybe to the bank account) than they are in politics and religion.

You also ask about biwiring a 4-ohm speaker system. All I can say here is, wait and read the 2150's manual. Maybe gonk can help you there.

As for differences in cable length, I doubt if the effects of any practical difference in length would even be measurable, much less audible. Maybe if the A cables were 10 feet long and the B cables were 1000 feet you could hear a difference. Maybe. As the English say, not to worry.

Looking forward to reading a full report once your 2150 arrives.

Thanks Paul! I'll be sure to post my impressions as soon as my RR2150 arrives. Hopefully the Outlaws have been able to aquire a few more of them. I'll just have to wait and see.

I should have figured that a 3 foot differece in cable lengths would not be an issue. I guess my main concern would be any adverse effects on the amplifier itself as a result of the A/B bi-wire. It'll be interesting to see for sure. Can't wait to test this out...

Thanks again!
