I own a pair of Parsifal/Encores, and am currently getting what I consider to be excellent reslults with believe it or not, a Krell KAV 500i (2x500 watts integrated) using balbanced outputs. I should add that the associated cables (IC's and PC's) are all top shelf (lots more $ invested in cables than in the amp), and I'm using an Electrocompaniet EMC I MKII CDP as the digital source. I have read (in an online review/commentary during research before purchasing the speakers) that anything below about 100 watts is really not enough for VA Parsifal/Encore combo ....... what are your expeeriences in driving them with your VAC? Obviously 500 wpc is overkill, and care must be taken. I don't know what your budget is, or if you are still in the market, but if you can tollerate only one pair of balanced outputs, the KAV 500i is something you can most likely afford (going for around $2250.00 used).... I have to stress that in this case, good cables (and balanced mode) make all the difference. I know this does not represent the ultimate in amplification quality, but it may well be the ultimate in terms of quality for the buck spent... in any case, I will one day upgrade to monoblocks, and would be very interested in your findings.
