If you're reading this, you are curious about this little amplifier. Build one (or many)! You will be amazed. Make sure all transistors are soldered where they should be, take your time to set the bias--and enjoy! The sound is amazing with plenty of bass. Cheers!
Having built a pair of ACA the ACA mini looked just the job for a compact amp to sit on my desk and drive a pair of Deware Tiny Radials I built from $20 plans. I'm feeding the ACA mini from a Dragonfly Cobalt USB DAC with a QED 3.5mm to RCA cable. The Tiny radials are 80db sensitive 57mm full range drivers that get down to 80hz courtesy of integrated passive radiators. The combination is fast and punchy, holographic, slightly sweet and more than loud enough. It's a very addictive listen as everything sounds so good sucking you in and making it hard for me to complete this review!
Huge thanks go to Nelson Pass for making this possible. This kit contains the hard to find parts needed to build the mighty little Mini ACA amp. It has matched Toshiba JFETs and also the coveted Harris MOSFETs for the output stage. The included PCB is an added bonus! This is, by far, the best value in the DIYAudio store right now. Get the kit; build the amp. You will be so glad you did. BTW, I built mine a bit different than standard with my own PCBs. But that's how I roll. :-)
I'm new to this world, having only built two of the ACA 1.8 amps before this mini. Bought the completion kit from the store to go with it. I loved this project. Very affordable, cool to look at, and amazing sound. I keep coming up with ways to case it, but like the naked look so much I never start the case. I like how it sounds and keep carrying it back and forth between work and home, then between different set-ups at home! May buy another one to build with one of the grandkids....
The mini essentials arrived completely undamaged and packed with the Completion kits I ordered. Thank you for the prompt delivery. I will give a more detailed review once I begin building the ACA Mini.
I got worried when the tracking app showed in the middle of Aussy Outback but na thats just DHL
It was sitting in my letter box in NZ, not a mark of dust on it well packaged, thanks guys, especially Mr Pass, can't wait to get the Completion kit.
