Spectron Audio Musician II Class D Amp - anybody still using?

If you wanna stay D I would recommend more modern tech like GaN.

That said I've never heard your amp and you really should compare before changing direction.

Look up Danny Ritchie of GR Research on youtube to see what he does with those speakers.

Thanks Roxy, I did watch it.....Same VA brand, but the one's I bought are a different line within the brand.  Still kinda troubling to watch though.  Does Danny like any speaker other than DIY kits?

Danny is first and foremost a salesman. All his videos are designed to serve one and only one purpose. 
 

John Ulrich died in 2015 but is consistently regarded as a magician with his amplifiers. The hegel 390 is a beautiful piece of work as well, and has newer technology in it. I’ve heard the Michi driving some somewhat underwhelming Martin Logan’s so I’m not sure whether what I heard was underwhelming because the speakers or because of the amp. 

Your viennas are four ohms and a rated at 89 DB’s so you don’t want anything too high-powered. I mean, most amps don’t run it anything near full output, but I would say 200 watts at the very top for your speakers. Anything more than that I think is going to be a waste of wattage and price.

Thanks for the information.  And how could I forget John Ulrich....RIP.  I am going to try my Spectron Musician amp with my my Baby Grands once they arrive (I just ordered them last week).  

I loved my Spectron M III.  A friend is now enjoying it.  Why not give it a try?
