I ended up building my own 1ET400A-based amp to drive my Directivas, but I will absolutely be buying one of these end of summer, because then I can bi-amp with digital crossover!

Also because following the development has been super gratifying and I want to support this project =)

That's great news, so when do you expect to start the first build?
Dying to see the build pics!
Good luck, anxiously waiting...
The input boards are in full production, just waiting on them to be finished from the manufacturer and in my hands. Hoping 2-3wks max

Would it be possible to do an MCH amp in the XL case mixed in with Hypex for surround/Atmos channels? I would be "very" interested in a 7 channel amp with 3 Purifi and 4 NC252 channels in one box.
Im also looking for multi channel amps in a two amp setup. Total of 7 bed layers and 4 atmos. Either 5Ch+6CH, or 7CH + 6CH

@Buckeye Amps - got updates on Purifi amp shipment dates? :)
I should have the Input Boards in hand either this weekend or early next week. So should begin assembly and fulfilment within 10days or so.

Any update on how things are going? Think we’ll see an Amir review soon?

Boards are in my hands tomorrow. And I already have a bunch of back ordered builds "ready" to drop the boards in and ship.

I have one customer who has volunteered his 3ch build to go to Amir. Depending on Amir's backlog once he receives it will determine how long until a review is up.

Not looking for any pats on the back. But I know my lead times have probably lost me some customers and/or had others question just how serious my business is.

I don't blame those thoughts. I definitely get it. And I know I've said a few times "things will speed up, just a little longer and I'll be ahead on orders".

Well, it's 5pm on a Saturday and I've already filled seven orders today.

I promise, I am working as hard as I can and appreciate everyone's patience. Wait tmes WILL decrease.

No rush on my part. Just excited to get my 3ch Buckeye Purifi amp hooked up for my front 3 channels. We all need to be patient, as this new board must be tested and once cleared for use the assembly should speed up considerably.

which power supply withy the 3 channel?
The SMPS1200.

When designing the 3ch, I talked with Hypex and they were very confident the 1200 would handle (3) 1ET400A's into 4ohms without limiting peak power. Testing so far hasn't shown any issues.

Dylan,
How is the heat on the Purifi two channel case versus the NC502MP after 30 minutes of use? Thanks!

This I haven't tested myself yet. Mainly due to the lack of NC502's to test with.

I am going to replace my workhorse 4ch NC502MP I have been using for LCR duty for two years now with a 3ch Purifi when I have a little free time, so I can report on the heat difference in my setup I notice.
However, the 4ch 502 case/design I am using is one of my first ever builds so it won't be a completely fair comparison to the new cases with more cutouts/etc I use now.

Does using the Hypex SMPS1200A400 power supply drive the 1ET7040SA module to full output power or leave something on the table?
