Al, my listening room is 13 x 21, with the speakers firing in the short direction. This room has wall to wall carpet, 8 foot ceilings and no treatments. I had the ERRx's about 3 feet off the back wall, until I read something about trying to make the reflected signal path at least 11 feet long. So I pulled the speakers forward, and now they are about 5 feet off the back wall and about 8 feet apart. It seems the soundstage opens up as you create more distance between the speaker and the back wall.
On that note, my impression is that my ERRx's are at their absolute best when reproducing music which was either recorded live, or was recorded to sound live, i.e. as a performance, with musicians and instruments located in a performance space. Symphonic music sounds incredible, as does jazz. Chamber music, small ensemble performances, are utterly sublime. There is something about the way the reflected sounds make my brain perceive the sources as located in space. You have to hear it to appreciate it.
Conversely, recordings which consist of electronic sources or signals sent directly into the board do not create quite the same spatial magic through the ERRx's, at least not to my ears. Perhaps because these recordings were created in a studio, with an engineer listening to a forward-firing pair of monitors, reflected sounds aren't such an integral component of the overall experience. I think my older rock studio recordings fall into this category. Don't get me wrong, they sound very alive and detailed; it's just that a wall of electric guitars and keyboards doesn't give me a spatial experience in the same way that a jazz combo or a string quartet does.
As for the speakers being forgiving, I would hesitate to use that term. The ERRx with ZMA will reveal levels of detail in the music which may have not been heard previously. But a poor recording can sound worse, and a poor performance may be harder to overlook (you can really hear when a musician is pushing or dragging time). Regarding sound quality, I have come across a few older poor quality LPs which sounded so harsh it was hard to listen to them. To be fair though, this might be more a function of my cartridge (2M Black) than the amp/speaker.
Lastly, as to listening at low levels, the ERRx's just amaze me, offering the kind of detail I associate with headphone listening. Here again, I can't say how much of the magic is due to the ERRx's versus the ZMA. I just know there is a lot of magic.
As I've gotten older my musical tastes have shifted more towards classical and jazz, and I am 100% pleased with the ERRx's; if I was 25 years younger and listening to more rock music, I might want to audition some forward-firing speakers with the ZMA.
