matthewpiano:Yes. I don't rate the PM4001 at all - flat, gutless and uninspiring sounding. The PM6003 is a much better amplifier all round with much more presence to its sound. At 6003 money there are plenty of different choices though, so it would be well worth taking some music and your speakers to a dealer so that you can listen to a couple of different options. What music do you listen to and what do you want to improve about your current set-up?
Currently I am using MS avant 902i speakers which I am partnering with the PM 4001 amp, i don't want to change my speakers.
I don't fancy the PM4001, so I am wondering if it is worthwhile to partner my speakers with the PM6003 instead, would I have a big improvement in sound. On a scale of 1 to 10 how big an improvement is the PM6003 over the PM4001. My other choices for amps are Rotel RA-04 and NAD C325BEE
I listen to all kinds of music, pop, classical etc.
