Hi Dom, i have the original muso which i used on optical for TV, and it got me interested in music and Naim again. When the Muso2 came out i was a bit sceptical, particularly at the pricing. Well, i listened with a few other folks at my dealer, and we all thought it really is better than the original. It just seems to do everything better SQ wise. I will probably buy a QB2 when it gets native Qobuz later in the year. As for wifi and hdmi, others will need to comment.
