ACA Mini Essentials Kit

Once again the ACA mini as a kit with essential kit components
At all documentation descriptions 5 stars ⭐️ ⭐️⭐️⭐️⭐️

I’ve build this amp over the past weeks, sourcing the PCB kit from DIY Audio store and the other parts from DigiKey and other sources. The parts kit was sold out at the time.
I bought a LRS 100-24 to embed the power supply in the total package and used an SMPS DC filter because off the good reviews. Based on what I hear, it certainly doesn’t hurt.

I have 2 ACAs that I use in bridged mono and everyone knows (or can read) what that delivers in sound quality.
I’m therefore so happily surprised about the sound quality off this little amp. In certain ways, it delivers more details or maybe dynamics than the ACAs do.
I would have to do more listening sessions switching back and forth to know. But not doing that right now. Just enjoying what I hear :)

amazing quality A++

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!

Best sounding for the buck. Thanks for the design Papa Nelson.

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!
