Virtue M-5001 Monos

Hello, I am wondering if there is anyone who has any experience listening to a set of Virtue M-5001 monos and if so, what is your input?
Do you still have yours? I read about your mods - I could do that. As I'm new to Class D and a bit tentative about this step, yet these look interesting - tho it appears Virtue is no longer making these. Perhaps 500ASP module is out of date.
