I haven't tested the MP573 extensively, so I'm mainly focusing on the build process and the parts. Although there is a high parts density, it's great fun to solder and build this preamp. The selected parts including the Carnhill transformers as well as the Grayhill rotary switch are state of the art. Fully assembled this thing weighs a ton. Setup process is easy. Luckily I did not f* up and got no mistakes so I could enjoy the MP573 right away. My first listening tests indicated a low-noise preamp with lots of gain and great functionality. Now I have to do extensive tests with different material and A/B testing with my other preamps. I'll keep you updated.

One's not enough!
This is an amazingly well put-together kit and was done in a slow afternoon. The sound is solid, even pushing on thick or massive (ya words), without being wooly. This pre renders a room with a very accurate sense of space - I would want to put up a pair for OH duties.
So far, just used it on vocal tracking where it's been a treat. Dialing up the gain while reducing the output is so functional in this pre - it's all smiles. Plus - there's the very cool faceplate and knobs.
PCB layout and quality is great, no issues whatsoever installing everything.
Next on the list is a second of these before trying out that Vari-mu comp! Thanks, JP!

Great kit
Very well packed with comprehensive instructions. Just unbelievably fast delivery inside EU.

Great sound, great kit
I've had it for about 5 years now and it sounds great on everything. Great clarity and tone. I particularly love the DI bass sound. Granted, I don't have day to day access to an original Neve to compare the sound, but it sounds great. The build was pretty easy, with good documentation.

Excellent
A fantastic device. Well thought out design and excellent sound quality. The stereo image is not affected and the integration of the remote control is very easy. Comparable devices cost at least 5 times more.

Excellent Compressor!
I bought this unit already assembled on Reverb. This a very musical sounding comp. I use it mainly on Bass but it works great on all kind of sources. You can dial in a quite heavy compression without it being too obvious. It does not color too much. This is a professional Hi End compressor. I like it a lot!

Wonderful Preamp!
I bought it already assembled via Reverb. Comes very close to the original. The quality is actually on the same level soundwise. Warm, punchy, yet wich great resolution and depth. It does have the "magic" in the midrange that one would expect. The DI works exceptionally well for Bass. A fantastic preamp, I want another one!

Great preamp with small part inconsistencies
Just went through the build process of this preamp, no major complaints other than two things:
1. My kit did not have the SIL2.54 13-pin 90° headers, but I received straight headers instead - I tried bending them to 90° with catastrophic consequences, but luckily I was able to McGyver my way out by dremel'ing out similar parts from my own stash of random SIL 2.54 connectors.
2. One of the output tranny screws was bent a little bit and had no threads on it (!). Local hardware stores didn't have an exact replacement so I had to go full DIY here also and cut the threads to the screw myself.
Without the issues mentioned above I'd definitely give this kit the full 5 stars. Nevertheless the preamp works & sounds great, and overall I felt it was an easy build. I didn't really mind that much about the extra steps mentioned above, in the end they just added a bit more DIY to the build.
I definitely recommend this kit even with the small issues I had!

5 stars is not enough!!!
Just finished my second MP 573...i really love this characterful preamp...it has all the classic vintage characzer, i was looking for...full sounding and handy bottom end, silky highs...extactly this "larger than life" i was reaching for...not a neutral, modern preamp, but still detailed, airy and very, very musical...5 stars is not enough!!!

Fantastic!
Brilliant unit. Bought two, easy build and set-up. Adds warmth and squeeze to everything, dial-able saturation. Sounds great on drumbus and mix bus. Thank you!
