Pairing with Vienna Acoustics Hadyn Grand&Rel B3?

Guido - I appreciate all your dilegence.

Interestingly enough, REL in their manuals suggest that the optimal way to connect to their SUBS is to the speaker terminals:
"It is helpful to know that you will almost always connect the REL to the input on the
rear panel labelled “HIGH LEVEL.” This connection is made using the supplied 34’
10” (10 meters) cable, the bare leads of which connect to the speaker output
terminals of the power amplifier. The easy and foolproof connection at the REL is
done with a Neutrik Speakon connector. The purpose of connecting to the speaker
output terminals is one of the unique secrets of REL’s success. By connecting to the
high level input on the REL from the amplifier, you build forward the sonic signature of
your main system, including the tonal balance and timing cues of the entire
electronics chain. In this way, the REL is fed the exact signal that is fed to the main
speakers."

As I wade deeper into the audiophile pool the water gets more murky :)

Thanks!

Yes, I am aware of that. The suggestion of connecting the Rel to the pre comes from Bel Canto. If you prefer to connect your Rel to the amp I suggest you go with Bel canto ;500 series, either mono or stereo. On Monday I'll investigate further with Soundings Hifi in Denver. They have a lot of experience connecting Rel subs to JRDG class D amps, which are of the balanced output variety like the Bel Canto 300 and 1000 series.

Apparently REL offers a 'digital Cable' whose purpose in life is to let one connect REL active subwoofers directly to amplifiers that have totally balanced outputs. . . that is active positive and negative leads. This cable has little circuit buried in epoxie, and a supplementary ground wire terminated with an RCA connector, which is to be connected to an RCA output of the preamplifier in the system.

The 'digital cable' makes REL woofers compatible with every current JRDG class D model, except for Model 102, possibly because 102 is not transformer coupled in the outputs. The compatibility of the REL 'digital cable' with Bel Canto 300 and 1000 series amps should be investigated with Bel Canto tech support at 612-317-4550, x.200.

Thanks Guido, my intention certainly wasn't to open a can of worms.

Danlalane, unfortunately the issue of balanced output amps and active subwoofers is in fact exactly. . . a can of worms. The good news is that now I have learned a little bit more about this topic than when we started the discussion. (grins!) g.
