The power supply boxes, one per channel, are almost the size of BMU's and both of these were plugged into the humungous MFBBMU, which 'sang' along with the music at first, but quietened down, thankfully, as the afternoon progressed and my ears recovered from the journey.
I'm not sure what kind of sound I was expecting from these in all honesty. I love the way the amps have with a musical signal, but these speakers, like their Allison ancestors, deliver the sound-waves in a different way to most other speakers. I have to say I was most impressed and went through track after track with my eyes closed and one in particular brought tears to my eyes... There's a HUGE advantage in having bass drivers directly connected to the amp, as the subtle softeniong effect of passive crossovers is totally missing here.
The main secret of these speakers (unfinished with lower units but truly representative of the Cube 'concept') is the bass and midrange clarity and musicality. What I'm going to say is valid I think to a thread we had some time ago about better systems and the way they reproduce less than perfect recordings. Led Zep II is one of those recordings where I believe the multi-tracks were recorded well, but some form of enhancement/compression was done at either the mixing or album-tape preparation stage, the end result being an powerful but often bloated bass that so far to my ears, no vinyl system can fully resolve. The Doc's rather special two-box Sony CD player had no issues here at all and the Cubes went on to resolve the bass and mids with no issues whatsoever. Indeed, 'Moby Dick' sounded superb, the distortion I hear so often being absent (the disc is the 1994 CD issue). The main driver being on top made no difference to bass and a wonderfully resolved airy feel to vocals, without ever sounding vague, 'over-ethereal' or room-smeary in the slightest.
As for the rest of it, I can't give chapter and verse on every track we played this afternoon, as the 'sound' gave way to the music so easily and totally. I'd love the chance to try angling (or not) the tweeter to see if this had any effect (this pair were slightly toed in). The treble was sweet and rarely drew attention to itself (it won't at all on vinyl I suspect).
In conclusion, I'm most impressed. I'm so 'conditioned' to direct facing speakers I find the sound of panel-type speakers and onmi's in general something that takes time to get used to. The Cubes do just what they're designed to do - work with the room instead of fighting it - and any stereo that stops me speaking for an hour while I get deeply into the music being played HAS to be a good one..
Trusting my ears is something I just cannot do these days
