My local dealer has a Sugden A21-a integrated for sale... Now this amp is rated at 25w 'pure class A' and it sounds fantastic with the speakers he has at the showroom (Tannoy's and Kef) but i dont know whether this will match the Paradigm studio 20? I have read a lot of reviews on this amp, but no one seems to have used it with my speakers.... The problem is that my dealer wont let me take it home to audition!!!! (Some stupid damn policy here)... Any ideas on how this amp will suit the paradigm studio 20?
