Jimmy3993, I can only guess that mechanical vibrations, temperature excursions, and who knows what else may have a detrimental effect. . . besides you have no idea about their past history. . . so, assume the devices are almost new and start break in from the ground up.

guidocorona -
sounds more reasonable than anything i can come up with.
another question for you - I am using the p9 pre from nuforce with the amps right now and the usable volume range seems to be from "0" to "4" out of 70 or so steps. So there is very little usable volume control for me. Have I done something wrong? Is it a pre amp issue? My "reference" is a mac integrated and while I never get past 40% of the volume wheel, there is much more usable room to fine tune volume.
Thanks for all the help!

Hi Jimmy3993, I can only think that someone tweaked gain on either pre or amps. . . this needs a call to Nuforce tech support. Guido

Hello Outlier,

Standard Musician III is not as refined as SE Mk2 (and by FAR!!!!) and you will be much better off if you will call Simon at Spectron and ask how to optimize your amplifier - he will give you a few advises for very inexpensive tweaks - which will work!

All The Best

While I agree that the SE MKII is superior the standard Musician III is still a very fine amplifier, I have had both, and in most cases it is all that one needs for listening to exceptional audio. The MKII is also more expensive (and by FAR!!!).
