Hi hgeifman,
No, nothing yet from my nearest retailer, unfortunately. I was hoping maybe they had a better line of communication with Musical Fidelity, but perhaps not.
I still think the M5si will be a good fit for me and will likely purchase. It's good to hear how much you like your M6. The only other integrated that I was still looking into is the Vincent SV-228. It also has all the connectivity that I need, looks great (to me) and has me curious about trying an amp with a tube preamp section. However, it's a little more expensive and has less power than the M5si (100/180 vs 150/270 at 8/4 ohms). For my speakers, both have enough wpc, but I need some good current output and I know the M5si delivers in that area. Not sure about the Vincent.
