This is an interesting report from Myles. I have not been to Overture, but I have heard the Q7s at Goodwins with the latest MIT cables and Spectral electronics. I think they were the new DMA 400 amps. Funny, they also have a Basis turntable, but rather than listening just to digital, I was allowed to play my own LPs. I was there to audition cables.
My overall impression was that the system was extremely resolving but I was not emotionally connected to my music. For the prices involved, I was expecting to be really moved. I wasn't. Perhaps the amps, cables and speakers all needed more break in time as they were all fairly new. Perhaps it was set up. The music just sounded flat and a bit ephemeral. It was floating in the space of the room but instruments and voices did not sound grounded in space or convincing. There was no presence. In fact, the presentation was quite similar to a demo I heard in another excellent room of the Wilson XLF speakers. Huge, diffuse image that was not grounded, lacking foundation and presence. Fast, detailed and dynamic, but not believable or emotionally moving. I just wasn't drawn in to the music.
I was surprised because I own SS electronics and Magico speakers and the two best demos I've ever heard were at Goodwins High End with the Magico Q3 and V2 speakers with SS electronics and turntables. In these, the systems were quickly and easily forgotten and I was just immersed in the music.
I've come to learn that great sound is the result of very careful component matching and system set up (room/speaker/listener relationship). And unfortunately, super expensive gear does not guarantee great sound and with a system such as the one at Overture, such high expectations are rarely met.
