Plinius SA250 Mk.4 vs. Pass Labs X350

Anybody compare these two ss amps? I'm considering upgrading my Plinius SA100 Mk.III amp. My associated equipment is Audio Research Ref. 1preamp, Meridian 508.24 CDP, Dynaudio Contour 3.3. Using NBS Monitor I XLR interconnects, NBS Monitor III speaker cable. Your thoughts/feedback are greatly appreciated.

What about the SA250MkIII with siltech silver wire upgrade vs. an SA250MkIV? The MkIII can be had at bargain prices these days. Is the sonic difference between the two worth the difference? I know this is slightly off topic but I think those reading this thread would be interested in this issue.

If I were you....I'd pick up a second Plinius SA100 Mk III and run them as monoblocks. I'm in the process of deciding between an SA250 or 2 SA100's as monos. I'm leaning toward the monos!!

Rayall: My understanding is that the MKiv has 4 separate toroidal transformers...and that the MKiii has one large one. In terms of sonics, many say that they are very similar...but some state that the MKiv was a significant improvement. The question is.....how much better is the IV if at all...and how much is that worth. This hobby is fun...but also can drive a person up the wall!!!!
