I’m excited to receive the m700/GCD combination in 2d, replacing my existing Rogue Sphinx v2 integrated with Mullard tubes, that my son will get as a nice hand-me-down. This is my first time with the forum.
My inputs are an Oppo 105D playing Tidal and CD’s. I have Magnepan 1.7i and a single REL T9i. With the Mullard-modified Rogue and the stock treble attenuators in place on the Maggies, the system provides a nice midrange and bass extension, but with some congestion and lack of clarity with complex treble passages such as orchestral climaxes and intense lead guitar.
In an old post, I saw that Paul liked Rel’s in general. An advantage is the high level connection via a Neutrik cable from the main speaker outs from the amplifier. This supposedly helps with coherence between the Rel and the main speakers. Rel’s instructions discourage use of a single sub with monoblocks. The alternative to getting a second T9i would be an RCA cable hook-up from the pre-amp, potentially sacrificing the coherence provided by the high level Neutrik connection. The problem with attempting a high level connection with two monoblocks is apparently the risk of a ground loop, with hum or worse consequences. A second T9i is not in the cards right now, but maybe down the line.
Does anyone have experience with this type of set-up? Does the presence of a second speaker output terminal on the m700’s come into play? Thanks in advance.
