As two mono blocks they simply sound amazing

I have enjoyed one aca as stereo but after using it as monoblock I decide to get the second one

As 2 mono blocks they sound fantastic, amazingly transparent, better bass but yet very pleasing

Surpassing the level of these couple of class A will defiantly be very costly

Amazing design so simple with such amazing results

A real surprise!

It was worth to wait, the ACA sounds amazing with my monitor audio Bronze 2
Comparing it to my LM3875 based previous Amp you get much more details and much better staging

Excellent kit / Excellent Overall Experience

As a new DIY audio builder, this was a perfect kit for me. I worked in the electronics contract manufacturing world for decades, but never made any of my own gear. The PCB was very high quality, well designed and well made. The parts kit was complete and organized. The build guide was excellent and well thought out (I built version 1.8). Combined with he support of the DIYAudio forum and the many articles available from Nelson Pass online, I learned a tremendous amount about DIY Audio and gained a lot of confidence for future builds. That combination really makes this kit stand out among other beginner DIY projects; It was a perfect combination of great product and quality education, not unlike an engineering lab class at the college level.

The final product sounds absolutely fantastic. I have a nice Yamaha receiver as my main system at home and had a small Lepai Class D amp in my office. This ACA Amp replaced the Lepai in my office and it was a tremendous step up in sound quality (I couldn't possibly go back to the Lepai, it made my ears tired after a couple of hours). It also surpasses my Yamaha receiver in sound quality. I have it connected to some Klipsch RB51 bookshelf speakers and fed by a DAC connected to my laptop and the system is wonderful in my office and gets louder than I would ever want. I find that myself getting lost in the music a bit to much these days and staying late at the office just to listen on many evenings.

The DIYAudio store has top notch customer service. From the time I placed the oder till the time I was enjoying music they were prompt, timely, communicative and have performance standards that rival the very best online stores. I will go out of my way to do business with them in the future.

Very good

I'm EU based, so only ordered the parts kit from DIY Audio, the chassis is from the EU in any case. I've been building Eurorack modules for several years now, which means I have familiarity with getting a bag of parts, a circuit board, and some kind of a build guide-- that's part of what I'll be comparing to.

PCBs and components. All top quality. Very nice sturdy boards, Bournes trimmer pots, .... the baseline standard is "very good to excellent". You'll have to work hard find better components.

Board spacing is quite generous. My biggest learning issue was bending the resistors 1/4 inch out from their ends; my habit from Eurorack is to bend right where the wire leaves the ceramic. Soldering was simple and fast. I did have to raise the temperature for one or two joins where the contract traces were larger; this is expected as the larger traces pipe away the heat faster. I mentioned that I have experience, I want to add that yes, I still use the printed circuit diagram and check off each part as I add it to the board. I find this really satisfying, like crossing items off your to=do list, and a key to any successful build is parts management.

Eurorack usually doesn't require a wiring harness (it is usually etched into the top PCB, and you solder the jacks/pots/switches/LEDS directly into the PCB), so making the harness was more mental energy than expected. However, the amount of supplied wire is very generous and forgiving, and the instructions clear and straightforward. I enjoyed learning how the author(s) structured and present the information.

The instruction manual is very good. It is clearly designed for a motivated novice, i.e. small steps with lots of detail. It is also evident that the authors have walked many people through this, and iterated the build guide as they did so.

I work slowly, because this is a hobby not a job, and spend way too much time on each design decision. I'm about 5 hours in and just finishing the wire harness. I think I could build it in half the time next time.

Great sound

Very happy with my amp camp.
I bought the aca 1.6 kit as my first project, it was straight forward to put together.
It sounds fantastic, very smooth. I use it with 8ohm 88db 3 way speakers, the sound good but miss tight bass, nevertheless the midrange and highs are fantastic and non-fatiguing.
I am going to build the M2X to have some more power.
The aca is definitely a keeper, also it dissipates 40watt vs the 160watt of the m2x, so useful for the hot summers.

Coming from the Heathkit, Dynaco and Hafler kits generation, building this kit was an easy and fun project. The build instructions and step by step layout was easy to follow. For the diy person there's no better enjoyment than to build your own great sounding audio gear. This Amp Camp Amp is a very clean sounding amp, you will not be disappointed

Easy to build, sounds great!

I've more than 30 years experience listening to Hi-End equipment, but I hardly found a solid state amplifier that's cheap enough and sound that good, the greatest part of this amplifier is simple, though the output just 5W (24V power supply, stereo), but it can drive my Totem Rainmaker (4 Ohm) with quality sound, and less than 10 hours after I finished the construction! I'm no good in circuit reading and complex wiring, but I'd manage to make this within one day and the bias adjust is easy! Highly recommend for anyone love quality sound!
