Speaker-amp synergy is also huge, making it surprising that there haven't been more less than glowing reviews of the ncores. TJ are you still using the Salks listed in your system profile?
After being a tube fanatic for over 30 years, I can now say that Class D is definitely here to stay. I may never buy a tube amp again.
For Ncore listeners that were not smitten with its charms, I suggest you view my post here about Ncore performance into low impedance loads vs. high. Low impedance performance was so-so at best while high-impedance performance is revelatory.
Tom,I'm unsure if I understand what leads you to conclude that the SMPS600 is inadequate in dealing with your noisy electrical grid. Your system, with the Ncore 400 serving power amplifier duties, doesn't perform well until late at night, presumably due to main's noise and distortion.How do you know that the AMR feeding the Ncore isn't the source of poor performance due to power supply inadequacy in dealing with mains pollution? Or your apple server, if not on batteries.Or the separately powered woofers in you Rethm speakers?The components I'm currently using with my Ncore 400s is an EAR Acute III cd player/Dac serving source and preamp duties directly connected to the Ncore and then on to the Marten Miles II speakers. I live in Brooklyn, NY where the power, day or night, in engineering terminology, sucks big time. And while the EAR CD player needed individual power filtering from its dedicated outlet (as did the excellent Aspen Lifeforce amp) the Ncores supplied by SMPS600s, sound, IMO, best without additional power filtering, plugged directly into the wall outlets. I say 'additional' because the smps600 incorporates a low pass power entry filter, addressing both common and differential noise. It is one of the few mains powered components that don't appear to benefit from auxiliary series power conditioning.To more conclusively assess the Ncore's need for a different power supply, one might evaluate the system using a conditioner(s) that provides isolating filtering, as well as a direct to wall option. The would help in determining which components and to what extent they're susceptible to power line noise. A multiple filter conditioner such as the Audience Adept would do quite nicely.FWIW,Paul

Now I might not have used the right terminology on the smearing effect, and I am sorry if I didn't. The vocals and instruments sound very clear on the Ncores, but when there are several instruments playing in the background, it does not separate and pinpoint the instruments as well as I have heard on a few other amps.
