REL Subs with H2O Amplifiers

I currently use H2O's Signature 250M (Mono) amplifiers in my 2-channel system.

I have a REL Britannia B3 Sub on the way.

In preparing to recieve and set up my REL sub, I was looking at the owner's manual (on line at http://www.sumikoaudio.net/rel/manuals/b_series_manual.pdf )

Having had a REL Strata-II in the past, I had planned to connect the 3 ends (+,+,-) of the Neutrik cable to the terminals on my H2O amps, as I had previously done with my Strata Sub. However, the B3 owner's manual recommends connecting the black ground wire to the preamp when being used with "Differential Output Amplifiers."

Because of the set up in my listening room, (power amps are not near my preamp) spliting up the 3 cables that make up the Neutrik connection will be a headache.

I have contacted Henry at H2O and he is looking into this for me.

In the meantime, is anyone using a REL sub with H2O amps? If so, what wiring configuration are you using? Are you running all 3 wires to the H2O amp, or are you connecting the black (-) to your pre?

From my past experience with a REL sub, I absolutely want the sub to get the signal from the power amps via the Neutrik connection.

Thanks

Barrelchief,

It was a month in between blowing the sub up and getting it fixed and hooked back up through the preamp. There was not enough of a difference that I felt like I lost something going the other route. My system has been boxed up for a month or so in anticipation of moving so my memories are a little cloudy at the moment. I remember thinking that it wasn't enough of an issue that I wanted to dump it in favor of something else. I hope this helps.

Thanks Snipes.

I hope that I have similar results and don't feel the need to change amps, just so that I can use the Neutrik

Assuming that your Storm III is now connected to your preamp; do you feel that you were able to obtain the same seamless integraton with your main speakers as you would have gotten if you were using the Neutrik connection via your power amps?

I will be setting up my B3 over the weekend and will have no choice but to connect via my preamp.

I tried above combo, using rca outof the pre-amp to the Rel. Unfortunately the result not as good as the neutrik!! not good at all.

I have seen a setup where there are two Rel Subs Stentors being used with Pass 600.5 mono amplifiers. He has the Neutrik connected to each amp with no ill effects to the system. Could be that your easiest solution would be to buy another Britannia....you may rather do that than to forgo the sub or change the amplification.
