we had a brief discussion here:http://www.avsforum.com/avs-vb/showt...783&highlight=
Eventually I demo'd the klimax and after reading all those raving tests my expectations were sky-rocketing. the product itself is a stunner, but unfortunately the sound didnt meet those expectations (in my setup) nor did the user interface, the one that comes with it is an insult to anyone who remotely understands aesthetics, it might be better by now though.
the differences to my oldish modified cd player (in the class of like a levinson 390) were there, more stable presentation, sharper, more fluid in a sense that it sounded less 'clocked', but it was also lifted up in frequency if that makes sense, like more mid definition and lifted highs, less bass heft. but overall the difference wasnt even in near relation to the costs. here is the killer: my wife asked me several times if I can hear a difference switching back and forth.
because i like well defined and weighty bass I couldnt name a clear winner despite hearing differences in slight favour of the DS. my old player did bass well, however the DS is probably better from there on. To be fair I have to say that we didnt use the same interconnects , linn dealer brought their linn cables which im not familiar with against my well run in straightwire crescendos. Also I had the feeling the klimax and/or the cables weren't run in or warmed up properly, it sounded a little forward to my ears during this short visit.
Overall, during this test, to me at least the difference sounded like upgrading to a better interconnect but not like switching to a much superior product like all those reviews suggested.
Anyway, a better choice for the money might be the acurate DS but I didnt get a chance to hear it. But before I make an attempt I want to wait until they got the UI issues resolved.
A little note to put this into perspective: I recently replaced my old earth/ground rod with a new heavy-duty copper coated steel rod and this had a much greater impact on the sound of the whole system for a fraction of the costs.
