Digital Amplifier Questions

I've been wondering the following:

1. Do digital amps benefit from being left on 24/7in the same way the ss amps do?

2. Is plugging a digital amp into a different outlet as your preamp as crucial compared to a ss amp?

3. Do digital amps have small transformers? If so, is distancing equipment from one another less important? (My peachtre Nova Pre/220 look best stacked)

4. When upgrading power cords on a digital amp, do you look for cords that do well with digital gear like your preamp and dac, or do you still go for a beefy cord?

I apologize ahead of time for my ignorance on the matter! Thanks!

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.

Guidocorona,
Have you had any experience with the Peachtree 220? If not, maybe you could pull up the specs and let me know what you think?

Mapman, Guidocorona, Timlub and Xti, thank you all for your helpful and informative posts! I appreciate it and hopefully others will benefit from this also.

Ps, Mapman, I researched Bel Canto last night and a pair of the Ref500m monoblocks and a Dac 3.7 or Dac 2.7 looks like that be an awesome system. You've got me interested in Bel Canto now :)
There's also a pair of Ohm Walsh 4's for sale local to me; if I had the $ for them I'd go listen to them.
