I did a review some weeks ago on a thread that Drummerman started, something like 'Let us be reviewers' but it's not on the forum anymore. For some reason it has been deleted. Sorry but I can't be bothered to do it all again! Let me do an unordered brain-dump of what I think...
In comparison to my old Kandy CDP the XRay 8 is clearer, more detailed, has tighter and deeper bass and gives the overall impression of being faster. On the other hand, the Kandy was better for rock music as it seemed to have a bit more gusto with some tracks, thus, you could say that the XRay is a tad polite on occasion. The XRay is more neutral and smoother compared to the Kandy's slight brightness or even brittleness (we're talking MK3 not L3 here). The XRay has a very slight treble lift from neutral but nothing to mark it as bright. The Kandy's bass wasn't as defined so when used with my sub there was more boom than with the XRay.
The XRay, Spendor and Rotel combo works rather well, especially considering how far behind the amp is in price comparison. The Spendors can present a huge amount of detail which I think suits the XRay well. They can also kick out a very tight and fast bass which, again, suits the XRay. The Rotel does a grand job but I think the bass definition can be improved, the treble could be smoother (an SA1 strength with the right amp) and the midrange could be more detailed (another SA1 strength but not an RA series strength!). I think the Rotel pulls it off because of it's musicality, i.e. it's verve, dynamics and punch.
I expect that the Arcam FMJ36 would have sounded more natural in this set up but my fear was a loss of excitement. The SA1s can really bounce along with the right amp. For £500 on the XRay and £200 back on my old Kandy I just took the plunge and ordered one and am now doing the best bit, listening 🙂
Good luck...
