Hello. I have for your consideration a barely used Audiophonics HPA-S400ET Class D PURIFI Stereo Amp. 2nd owner. I'm not interested in trades at the moment.

It has 3 configurable gain stage settings! The only PURIFI Amp I know with this feature.

I'm asking $1300 shipped via FEDEX. This is a great amp here. Measurement are insane on PURIFI modules. Awesome amp. I love it so much I bought a 3Ch PURIFI for my FRONT 3, and selling this one to buy an 8Ch NC252 to consolidate my amps to 2 boxes for 11Ch, so this one needs a new home.

It is in great physical, and excellent working condition.

I can deliver it, or meet up, within reasonable distance in NJ/PA etc.

I am a US Marine, and an honest seller with many online references. I’m an established seller here, eBay, US Audiomart, Audiogon, and various other forums. I can provide those upon request. Thank you for your consideration.

FYI: This amp has no 12v trigger, as it was an option added on later units.

I have this amp and love it.
Awesome amp. I loved it too. I still stayed with PURIFI though. I found a great deal on a new Nord Three 1ET400A MKII 3 Channel (Sonic Imagery 990 Enh) monoblocks config for my 3 front channels!

Amp arrived today. Just plugged it in and took a quick listen.

Here’s how I can best describe the Purifi:
This thing makes my Dynaudio Contour 20’s play cleaner on SPOTIFY NORMAL than they did on Tidal HIFI with my Parasound 2125. The veil was pulled back. Awesome clarity! Fantastic amp. Thanks, Geronimo.

Here’s what Audiophonics has for their own measurements:

So looks like 110 SINAD at 5 watts for 8 ohm…. and 118 at 100 watts.
