These smaller ones are ideal for the room size simon. Anything larger would be too much I think. I have a Sony CDP-591 now (sorry no pics yet, I don't have a digital camera and if I did my Mac doesn't have USB to upload them) courtesy of Rory and UPS. The brighter sound I was expecting is not too prominent as the overall balance is just right.
It is difficult to sum up how this little system sounds. In the main I am amazed and really really surprised. It's the bass actually, it's incredible and not expected at all from such small boxes. Listening now to Peter Gabriel and I hear lovely deep, smooth and tuneful bass at moderate volume and then POW, it goes even deeper and more glorious. I keep looking at them on the wall to figure where it's all coming from. I just haven't noticed this with my main system which has bags more treble detail (more hi-fi?) and bass but not this impact. Also with these JPWs the vocals leap out over the top of everything and grab you by the short 'n' curlies. I am hearing music more like it was heard in the studio, I'm pretty sure of that.
I would love someone to call round and hear these because something has clicked into place to create a magical experience. I have been to Tony's a few times and been gobsmacked by that 'being there' sound, and attended bake-offs so I have heard very expensive systems, so I know what to strive for. With these speakers and the Alto I have achieved something quite extraordinary. As I said before, maybe it's a special synergy of large drivers (for the cabinet size) in closed boxes, a rather special little amp, the smaller confined room with only one door and small window (far more intimate) and rock solid wall mounting to allow the JPWs to perform to their best.
