There have been quite a few inquiries about the MSB Technology M500 monoblocks, which I was able to listen to in my reference setup/room after the Munich High-End Audio Show 2019 and which many of you were able to hear at the show. The main topic of the questions was, if the first prototypes differ from the current production version. 

The current production version has more heat sink area, better internal cabling, shielding and standard PCBs instead of handmade prototypes. And yes, as guaranteed by the MSB technology, the production model sounds even better.

The brand new M500 set is is coming to Mono & Stereo and I'll summarise the review as soon as it arrives, and I do my final listening.
