Nearly done...

ACA is warming up for the bias adjustments, just need to get the holes drilled for the switches in the front plate.

Testing on speakers later tonight... as seen on the pic, the power jacks are mounted on a piece of plastic screwed to the back plate, so chassis not at ground. No feedback to my earlier question, so went ahead - no smoke and I'm still here...

Default Listening impressions

My system has a B1 clone feeding the power section of an Accuphase E-206 driving a pair of bofu + supertweeter full range speakers.

Swapping in the ACA, I noticed a larger sound stage - width, depth and especially height. Separation of instruments and singers was greater, I was made more aware of the surrounding space.

Top end was highlighted more with greater sibilance, but not to the point of objection. Bass was tight and well articulated, and the mids were nicely fleshed out. The sound seemed more liquid, the Accuphase seemed drier.

Overall, very pleased with the results so far...

Thank you Nelson and the Diyaudio team for making this all possible...

Default Very close now..

While Mark has been busy in San Francisco preparing the next batch of ACA kits, I've been busy in Italy working with fellow audio fanatic Andrea at Hifi2000 on some really nice cases to complete the amps.

We hope you like the look of them. This is just a set of teaser photos of some prototypes and some small details will change (including the addition of some custom CNC detail work on the front and silk screening on the back) but I can assure you they look gorgeous in the flesh. More photos to come later this week!

Durable, high quality Dupont gloss and matte enamels, the usual Hifi2000 fit and finish and and of course everything will just bolt straight in. We did a lot of listening tests on various configurations, swapping DACs, Speakers, Amps, Analog/Digital sources, Single and dual PSUs, and using 4 to create a quad-mono biamped setup which had them punching way above their weight, especially on the larger speakers.

We've sourced some special packaging just for these cases which will provide an excellent guarantee of them arriving shiny and new.

I hope to have everything set up to start pre-sales this week with delivery a few weeks after. The standard color will be a 10mm silver front panel and matt black enamel, to match the other chassis we have in stock. However, we'll be offering a limited run in the presale with a 10mm black front panel and the body a beautiful and durable, high quality enamel finish in a shade of red whose name we can't mention but is commensurate with the quality of the finish Let's just call it "Electric Red"

Andrea is a great guy and a really passionate DIYer. It's a family business in every sense and they are intensely proud of their ability to make the highest quality product on the market.

We may be able to have a few more options than normal for the presale. I'll start a discussion thread on that later in the week and link to it from this thread. You'll be able to voice your request there and see who else chimes in - if there is enough demand for a certain look then it may be a possibility.
