toobgroover - that dsp-1 was the 1st ambient-surround set-up i heard, & i wanted it *bad*!!! a few years later, s'phile reviewed the jvc-unit i now have, & they said it was in another league from *all* the processors awailable at the time, including the yamaha & the lexicon, which were also highly rated. well, it was yust a matter of time before i knew there'd be one in my system. when i finally had the $$$ & the space for one, it took several years to find one, at *any* price, forget a reasonable price! i'm glad i have it, it's really nice for good 2-channel set-ups, & makes multi-channel recordings superfluous, imho. too bad these yamaha/jvc-type audio processors never really caught on... yure right about it being unobtrusive - if it's set properly, ya don't even know it's on - until ya turn it off! :>) dig that thing out & put it to use! ;~) doug
