Yashu, sorry for delayed response. Mine is on top of my rack, so I have no issue. However, it never gets hot or even warm, and sometimes I have CD's piled on top. Also, there are no vents on top of the K-03, so I doubt there is any heat dispersion issue on top.
As always, room and system synergy trumps all, so no one can tell you what the Esoteric will sound like in your setup. However, as Guido said, the Esoteric has filters that can subtly alter the sound. And if, like me with my Mcintosh MC452 amp, you have a slightly warmer/lush amp or preamp, the Esoteric might be a good match. However, if, like Kiwi, you like a very lush sound like your old (and Kiwi's own) Cary CDP, which are known to be euphonic, the Esoteric may not be your cup of tea. I will also add that the new K series is definitely warmer/lusher than the old X series, so I would probably discount those comments regarding the X series.
Hope this helps...
