Hi all, recently bought 8xpdqx to replace Roksan Kandy L.III (which I think is a cracking amp), I read good reviews about the 8xp and 8xpd on What Hifi and decided on a audtion the QX version vs Naim Nait XS at the same local dealer. I thought the Cyrus was in a different class and had the sparkle and detail I was looking for. Hence i bought it without a second thought.. At this point i'll explain that it has replaced the Roksan to partner Quad 12l2 on partington super-dreadnought stands, and Arcam CD73T and a Squeezebox duet(via digital coax). All for the time being as who knows when upgraditus will attack again! I noticed that the 8xpdqx didnt have the scale and bottom end of the Roksan but beat it hands down for everything else.. problem.. I like scale and bass weight. Question: 1) will things improve as the amp 'burns in'? If so, guestimated burn in time? 2) How would an PSR-X help? the 8xp is the same as the 8xpdqx without the dac+qx, right? the review of the 8xp from what hifi says: "It's also true that other amps have greater scale, but the Cyrus' many other qualities easily make up for that. Besides, if you want the pace, detail and transparency of the 8 XP, but with extra authority, you can always take advantage of the Cyrus' upgrade potential and add a PSX-R power supply. It might take the total cost up to £1750, but it'll take much more expensive systems to the cleaners." Would a PSR-X really give me "extra authority?", and by this do they mean scale and bass weight? Finally 3) How good is the Dac in a 8xpdqx? is it on par with the latest 8 series CD player (not the dac-less transport)? I've rambled on a bit.. anyone got any ideas?
