I just pulled the trigger on two new items: 1. A BHK Pre, and 2. a Signature 250 power amp (due to take delivery later in the week), and had a question: I use an REL T7i Sub, which includes the wiring option of a three-wire configuration directly from the power amp speaker taps. In perusing these forum pages there seems to be contradicting information on this: Some have claimed to use RELs in this manner with the 250 power amp with no issues; others (Including Paul McGowan) indicate that this should not be done because the 250 is a fully balanced amp. So what is the right answer? Should I or should I not use the REL sub with the 250 in this manner? (The alternative would be to hook the REL up to the pre in a “traditional” manner.) A quick scan of the online user manuals didn’t yield any information, but I might have missed/misread something. Any information would be helpful.
