Note:
1. I run the Accuphase DP-75 directly into the Pass X350 via the Cardas Golden Ref XLR cables for CD playback. The ARC LS22r comes into play only for phono and tuner. It's a bit of extra work, but the results are worth it.

2. The Linn Sondek LP12 is sitting on a 90 pound slab of terrazzo marble which is in turn supported by three Nordost cone and saucer isolation devices.

3. With respect to system evolution, adding a pair of Pass X600 amps would be a nice improvement. I will probably keep the X350 for use in a biamped configuration. An ARC REF 1 or REF 2 preamp with the right tubes would make the the current preamp bypass unnecessary. At some point, it would be nice to upgrade to a pair of MR20.1s

I'm researching a makover for the 20Rs. The focus of my research addresses two areas:

A. Magnepan's middle-of-the-road crossover parts selections and

B. An acoustically and aesthetically non-intrusive means of stiffening the overall speaker frame and incorporating some decent stands.

I think that there's a lot of potential yet to be realized in the stock MG20R design.

Should these improvements prove successful and significant I'll offer them as a kit or as a service to MG20R owners. The same methodology can be applied to the 3.5/3.6 as well. I should have this in testing by the end of March. The crossover parts are on the way and I'm finalizing the CAD drawings for the stand/frame stiffener. Stay tuned...
