is the Peachtree Gan400 discontinued?

You might be right. I was on their website about a month ago and the Gan 400 was still listed. I just went on there again and it seems they discontinued all power amps. Just listing a few integrated amps and the Gan 1 Bluesound combo and that’s it.

wired its not on their main page any more and the link below shows discontinued

As far as I know it’s not discontinued, it still is their flagship power amp. But they also came out with the Gan 1 and the Carina Gan. The Carina is a Gan integrated amp with Dac I believe,  and the Gan 1 is kind of like a straight wire with gain that only has a digital input, I believe that all you could plug into it is a streamer Dac. The Gan 400 is just a straight up power amp, they are all different.
