Do Plinius amps have high frequency anomalies?

I have Shahinian Hawk speakers. I have tried driving them with two different models of Plinius amp and they both had an effect on violins and trumpets and sometimes voices which I would describe as "electronic." I perceive the area of principal coloration to be in the sibilance range and it seems to add a slightly whistle-like character to the sound, especially at high levels. On some (maybe rolled-off) recordings, this emphasis can be attractive, enlivening the string and brass sheen that occur naturally; but on most cd's and lp's, the effect is not to my taste. The two models I tried were the P-8 and the SA 100MkIII. The latter was the smoother and more realistic sounding but they both exhibited this coloration I am describing.
I am just wondering if any of you have experienced this with Plinius amps or if any of you who have heard Plinius amps would like to offer commentary on their high frequency performance.

I use Kimber cables, recommended by the speaker maker, not necessarily the amplifier maker. I do not believe them to be high-capacitance.
The SA 100MKIII is very impressive in its ability to capture nuance and reveal internal lines in complex orchestral passages. It has great bass (delineation and control), fine dynamics, and very good timbral accuracy throughout the orchestral range. Add a huge and very broad image, with great height and depth, ignore the high running temperature and the heavy electrical drain and, if it weren't for this zinginess I've described, I'd be quite happy.
I might just experiment with speaker cables. Changes of interconnect have not helped.
