Not many people seem to be aware that there is an Open Baffle/Dipole sub available from the two companies who developed it together, GR Research and Rythmik Audio. It has won "Best Bass at the Show" for many consecutive years at the Rocky Mountain Audio Fest. It is the Rythmik A370 plate amp incorporating a shelving circuit to counteract the natural acoustical low-frequency roll off resulting from the dipole cancellation of the two opposing GR Research 12" OB woofers which are installed in an OB H-frame. It works particularly well with dipole speakers like Maggies, having the same figure-of-8 radiation pattern and a very "quick", nimble sound, with none of the typical thick, ponderous, room-loading sound of both sealed and ported woofers. You can read all about it on the GR Research website, (in the product listing for the OB woofer) and in the GR AudioCircle Forum.
Magnepan 1.7 to 3.7i or Pass Labs XA60.5 to X100.5
I'm in the process of upgrading my system and facing a choice. Currently I'm using an pass labs amplification (XONO, X1, XA60.5) feed by Michell Gyro, SME IV and Shelter 90x and ending with Maggie 1.7 (mye sound stands).
I've listened to both 3.7i and Wilson Sabrina, Sashas, all of which could benefit from a bit more amp.
I have a dedicated music room (12x10) and listen to late sixties classic rock, country rock, folk as well as Cash, Owen country and vocal jazz.
I have trade-up value for the 1.7 at my dealer as well trade-up value on the XA60.5. I could probably stretch to a demo pair XA160.5 but am concerned without a dedicated power outlet I'm taxing the system. Also by the way, I don't tend to push the system beyond a bit past midpoint on the pre-amp, although the XA60.5 class-A meter dances about on complex crescendos.
Two question. Upgrade amp or speakers first assuming only one change for the next 12 months? If the amp, is the XA100.5 enough of a jump?
