Very nice work Nebby! I love that you took the time to make panels to cover the driver flanges, that makes all the difference in the world. Can't wait to see it finished, and the Cherry looks gorgeous. How does it sound?
Here are the pics. I'm already thinking of doing some mods, haha ;p Some nice front panels from FPE might be in the future, or maybe even some of Steve's awesome work.

These cases are anodized all over. They pick up fingerprints like crazy, so they need to be cleaned. I couldn't be bothered before snapping som photos, though

just finished my largest project so far: a pga2310-based preamp with headphone stage. my main goal was to support blind A/B listening tests, hence I got to utilize a microcontroller and spend a large part of the effort on the software

you can find more details about my build here
It's really nice to see professional work of this level.
Ausgezeichnet Werk, Herr Steinchen !

I really liked the defoamed 650 out of the β22. I also listened to the 600 and 580, all of which had the APS defoamed mod. I bought the 580 on the spot.
I was very surprised, as I've never cared for Senns. before hearing them through the β22.

To be honest the sub couldn't have been done without my friend Guido who did most of the hard work with the design actually, I was mostly learning from him and following his instructions
The cherry panels have darkened a bit over time and have a much nicer color now imho:
The sub sounds very good, my goal during the design/brainstorming phase was to have a fast, accurate sub that could go low, yet could also put out enough boom to be used as a HT sub. I'm thinking of building a small version to use for my bookshelf speakers I'm currently building.
That's a very nice amp you have there fierce! Just one question: why are your rear xlr's mounted from behind the panel but your front jack mounted on the front?
I've recently had a chance to build an over-the-top transportable Pimeta with all the little additions I wanted.
This Pimeta runs off OPA637/OPA627 opamps with Millet Hybrid Discrete Diamond Buffers on Left/Right and a Sijosae Class-A Diamond Buffer on Ground.
There is a trickle charger for the 11x 650mAh AAA battery pack I soldered together. With the diamond buffers set fairly high (25mA each) battery life is about 10 hours. Of course, this could be lowered without much sound quality degradation.
This thing sounds fantastic and gives some chase to the PPA I'm using, but just can't catch up. I'll be finally having a chance to compare it to the PPAS, although I'm pretty sure which will win.
