Anyone using, or used, Peachtree Nova amps with SDA 1s?

Specifically Nova 150 or 300. I have SDA 1c speakers with updated xovers and new tweeters (along with upgrades to enclosures).

If there is an existing relevant post I was unable to find on app version of forum.

    If they're common-ground, I'd expect them to be fine. A 6-ohm nominal load shoudn't be a challenge for a competently-designed amp.

    The problem is that there are so many INcompetently designed amps sold under both new and established brand names.

    Aren't those class D? Not common ground?

    I am using an NAD M22 v2 with my SDA-1Cs with updated tweeters. Definitely class D and common ground. Sounds great!

    The Peachtree NOVA 300 was measured in Stereophile so you can see how competent it is.

    I auditioned in store (NOT SDAs (GE 5s)), was pleased...seemed more musical than my previous. Replacing a NAD C390DD (class D, common ground) that is now best suited for use as a small boat anchor.

    Thanks for the feedback (and I think I've read every available review of the Nova 150/300s). Just a bit leary of the more complex amps after writing off a fairly pricey amp, so all the built ins are a bit of a deterrent. Going to audition it and a PrimaLuna, with much less WPC.

    I was involved in a conversation with another about this. From Peachtree, "All of the Nova power amplifer sections are fully-differential designs", which should mean they are not common ground.

    You may want to look up Peachtree’s customer service and QC. Both have been questioned in other audio forums.

    From Peachtree:

    Hi Paul,

    Thanks for writing in. Since our amp is internally bridged, they do not have a common ground.

    I hope this helps, please let me know if you have any other questions.


    Sincerely,
    ****
