Carnhill Charm

I just finished my first MP573 build, and yeah there's a reason why this style of preamp has a place in history. On my first mic test, with just a standard dynamic vocal mic, it took me about 20 seconds to dial in the right amount of gain and sonic character my ears have been hearing on the radio for decades. I can't wait to power up the U87 and Mojave MA300.

I bought this 1073 build specifically due to the fact that it uses the Carnhill transformers. I've used plenty of 1073 clones ( personal builds, and otherwise) and I can say for certain that without them in the circuit path you will never recreate the sonic breakup character loved by so many (Audio geeks and just music lovers etc).

Hearing is believing!!!!!!
Super well done to SSK for some fantastic circuit engineering.

Cheers.

Awesome thickness!

This was my second Sound Skulptor pre, and like the first one, was very easy to build due to the very detailed assembly guide. Every component is of high quality. But here comes the best part: the sound of this pre is unbelievable! It makes everything sound thick and full. Amazing on any instrument or voice. If driven hard on drums, it does that beautiful saturation, cuts down the peaks, while adding even more punchiness to the sound. Gorgeous!

WONDERFUL-sounding compressors!

These compressors were a very easy build, with fewer components than other Sound Skulptor kits.
This is a nice payoff, because you get a phenomenal sound for quite a small effort.
VERY glad I purchased. They are installed next to my CP4500, and my two CP554s.

Incredible compressor

I built two of these mono units in March 2024.

I work for the national broadcaster in my country and I have been using these on individual bus and master bus duties for my music recordings ever since.

Authoritative, full range, sublime.

They can be transparent if at 1.5 ratio with a low threshold, or give you very solid control with a ratio of 2 onwards. The threshold control is important and powerful.

Wonderful kits, they complement our genuine Neve 2254/E units perfectly. I think these are a viable replacement for the real thing, in a time when the real ones are getting much harder to find.

Perfect!

This is a high-quality and useful piece. Kit instructions were great and it went together quickly. I have it standing vertically in the center of the speaker shelf on my console with a 500-series Bluetooth module in it, and wired it into one of the master section tape inputs. It’s dead silent and works beautifully!

Definitely worth it.

My favorite DIY preamp. Brilliant and clean sounding, one doesn't have to be professional sound engineer to note the sound quality of this preamp. I am a beginner when it comes to building DIY stuff, still managed to build it and really happy I made the decision of purchasing this

Very flexible limiter/compressor

I've been using my CP1176 for about 6 months now, on two to three sessions a week. After getting to know it well, I can tell you all with confidence that it is a great limiter & compressor, I thoroughly recommend it. It really does grab the attack at the quoted 20us while remaining transparent. A friend has lent me his unit and I've been using the two on my front end: the first set as a traditional limiter (super fast attack and fast release) with input (threshold) set to just catch the peaks, and the second as a compressor, with say 5ms or more attack time and slower release. This is an awesome combo and is giving a lot of clarity to my mixes. I've used it on vocals, acoustic guitar, electric guitar amps, bass (both DI and amps) and piano (no drums yet). Perfectly useable on all these sources.
Things I like:
1. Attack time 20us to 20ms. This varies from the "real" 1176 spec, whose slowest attack time is 800us (0.8ms). Having this longer attack time allows you to use it as a compressor and preserve some transient attack. This is a very worthwhile change to spec.
2. High Pass Filter. I use this nearly always on bass, it is a great feature.
3. Very accurate gain reduction metering. The 1db LED steps are great for dialling in the right amount of GR.

To the designer: Wishlist:
-switchable HPF of 80Hz and say 160Hz.
-Get rid of the DIST feature - I've never found a reason to use it. Perhaps replace it with a LPF at say 200 or 250Hz?
-External sidechain access (I understand 500 format makes this hard)
-a stepped pot version for those intending to build units for stereo use. I've used them in stereo and wasn't convinced my level calibration was correct.
-re-label the OFF switch to ON!!!
Keep up the good work Sound Skulptor, this is a great piece of equipment. I'm amazed at the pcb design and how you've managed to get so much circuitry in a 500 format unit.

Very clean sounding

I built a pair of SK99s to try against the 990C+ amps I had. They hold their own with no problems. Almost indistinguishable, but I can't really tell which I like more. The price difference is a tie breaker.

All of the above

I can just wholeheartedly confirm what everybody else is saying. This is another top-quality product in every way: sound, looks, feel, documentation, support, ease of build, parts quality, PCB quality. etc. at an unbelievable price. I've built many kits from many vendors at this point. Sometimes, some are as good as Sound Skulptor kits, but none are better.

Another slam dunk

I'm on an ongoing quest to build 500 series gear from as many DIY kit vendors as I can. There are significant differences among them: the quality of the components and PCBs, the sound of the products, the documentation, the ruggedness, the design, the support. Sound Skulptor keeps floating to the top as the one that's delivering the goods on all fronts, and I keep circling back to them for that reason.

The MP-566 is no exception. It is a proper tube pre with great tube tone. Tastefully designed, easy to build, feature-packed. I expected it to be a niche-sound, but it can deliver a ton of gain, and it now sits up there with the best of my pres, some of which are pre-built units that cost five times as much. I would give six stars if I could.
