Pops,
At home I listen primarily to digitally sourced material from a music server. I listen to my vinyl rig only where I don't have something on my server (chalk it up to extreme laziness). But, I was struck at this show at how much better vinyl sourced material sounded, particularly where a sort of comparison could be made because the setup included both analogue and digital source components. Good rooms sounded good with both types of sources, but, there was a bit more "life" with records, compared to digital sources. In the Surreal Sound setup, you could easily hear the difference, with vinyl sounding particularly good, some hi-rez digital also sounding very good, and CD or CD resolution material sounding good but "missing" something in direct comparison.
I also liked the Tron gear and vinyl only setup in the Highwater room. The sound was quite musical and engaging. I should have mentioned the Horning speakers in that setup as being among the better speakers. The system had the kind of dynamics and "speed" that I like, although it was a bit more strident and peaky in the upper treble than the Surreal Sound speakers (smaller room with speakers closer to the listener might account for this). Still, this was an enjoyable system.
I have heard the MBL speakers sound very good at times, and they were pretty good at the show. Their strong suit is imaging (very expansive soundstage without sacrificing specificity of placement of instruments), incredible stability of imaging and consistency of tonal balance over a WIDE listeing area (good imaging even sitting outside of the right or left speaker), and ability to play at high volume. Bass in the MBL room was a touch one-note boomy (I have noticed that this speaker is hard to get the bass to sound right, but, I know it is possible because I've heard it sound better). For my particular taste and requirements (particularly the ability to maintain "liveliness" at low volume levels) the Surreal Sound and Deja Vu vintage system is more to my taste but I can easily see someone with different priorities thinking this was the best system at the show.
