Digital Amplifier Questions

That's interesting to hear.

I know the technology continues to evolve and noise isolation is an important part of the overall equation.

I find with the BC ref1000m, with just a little physical isolation from other components, as seen in my system picture, the only noise issues I encounter is with unshielded ICs. The DNM Reson ICs are my preferred ones in my main system and I am able to use those to good effect from pre-amp to amps, but I do have to play with the physical location/path of teh wires to avoid RF noise. With other more common shielded ICS, it is not an issue. I With things set up properly, I can put my ear up to the isotar tweeters in the Dynaudios and hear nothing with no music playing. So its just a matter of proper setup to provide teh extra touch of isolation needed, which is never a bad thing to consider doing.

Guido,

Any familiarity with the Class D audio amps? These seem like they must be a great bargain. If teh noise isolation is up to par with the latest and greatest as well, that might just be the icing on the cake.

Hi Mapman, no I have never had an amp manufactured by Class D Audio in my system.

Every component that I've ever had, preamp, amp, dac, etc, has benefited sonically by leaving it on. Even tubes, I eventually turned off my tube gear to save on life, but on long lasting pre amp tubes, I did experiment over a few weeks never turning them off and you could hear it.

Yep... Worth pointing out that my old Rowland M7 monos, which were almost class A amps, reached best performance after one week (yes, that is 7 days) of operation... Tried that one fine Christmas break... The creatures sucked up 720W per side for some three weeks... By the end of the first week they did sound really golden... When wifie received the AC bill she almost threw me out of the house.

May Gaia bless class D... Rowland M925 monos are on 24/7, and I never heard one peep of complaint from Mrs. Better Half.
