Rafael,thanks for your input. My opinion was based on the Musician II which was VERY powerful but far away from musical. It just had no soul. At that time the Plinius' top of the line was the SA-250mk4 and was both powerful and musical. I've no experience with the current Spectron iterations but I prefer to stay away from Class D amps for the time being as I also tried a couple of others and wasn't impressed. I do understand that with Class D, one can make a very powerful amp with less cost etc..but I still think this technology needs sometime to approach the best of the 'linear' SS and tube amps of today in how they
dig into the soul of the music.
But, as always, the milage may vary. I know taste also plays a role in this.
Best
AG
