Plinius SA-103 compared to the SA-102.

I have been reading threads all over the interwebs about these amps and I haven't found a definitive answer to the this question: Has anyone done a listening comparison between these two, preferably at home, but at least at a dealer? Most comments seem to echo the thought that the SA-103 is essentially a cosmetic facelift of the SA-102, but a couple of comments imply that the 103 is a tad more open in the upper registers and a tad more neutral (meaning a little less warm) than the 102. The specs certainly would indicate that they are essentially the same. Has anyone heard these two amps in the same system?
