last time in the thread I bought the Parasound a21 and the p5 pre for my Mozart speakers and still felt something was missing? ran into a local dealer that I have known for 20yrs and haven't seen for a while and of course are conversation started with what kind of system are you running? he suggested a Musical Design amp and pre to work around the Mozarts or a different set of speakers for the Parasound gear, he felt the Parasound was not a good match with the Mozarts and gave me a Musical Design amp and pre to take home and try out. and man was he right I noticed the difference immediately not just a different sound but a noticeable change. it brought the mozarts outta the dark leveled out the bloated bass, gave the mids a fast powerful punch! and made the tweeters sizzle. the mozarts sound very natural and organic now. so I will be putting my a21 and p5 up for sale so if anyone is interested drop my a dime.
Hi Jughead, does the Musical Design amp run balanced or single ended?
