At burning amp you mentioned that the plan was to have a modular Burning Amp, where you could swap out front-ends and output stages. Is that still the plan, and have you made any other progress towards that goal? I think it's a wonderful idea.

Two different aspects to that:

Firstly, I think the Burning Amps are intended to be "composed" into different configurations: that's why there are two front ends (balanced and unbalanced), bias boards, and two back ends (BA-1 and BA-2). So the intent is that anyone can pick the configuration that makes the most sense to them, and build it. Because the board mounting points are standardized, it should be easy to re-use chassis and heatsink.

Secondly, my goal is to gradually enhance my system, preferably without throwing things away. So I have a single stereo F4, fed by BA-3, fed by a passive control unit (First Sound). Ultimately, I'm thinking of building another F4 so I can bi-amp, and replacing the First Sound with an Arduino-based volume and relay-based selector module. My long-term goal is a completely home-built, state-of-the-wallet hifi system. I already have speakers, some cables, pre and power amp. I'm keen to build a computer-based playback device, and if I can get time enough, to learn machining and make a turntable and arm.

These are of course long-term plans. I also have to get two kids through college and avoid foreclosure .

To that end, I should really be selling the gear I'm replacing: a Music Reference RM-9 and an Audio Research LS-3.

Really well done.

Can you elaborate on the case construction? Supplier, tools you used vs what you had done by a shop, and cost?

Thanks NYCOne...
The sides, face plate and rear plt,, are 3/8 x6 flat bar, top and bottom covers 1/4 x8 flat bar,, rec tubes are 2x5x.125 thk. corner blocks (hold it all together) .625 square bar.. All 60-- series extruded alum... the 8 wide flatbar came from metal by the inch.com,,, all the rest came from online metals.. cost about 225.00 (just the metal) Screws, taps drill bits and other little bits came from the local hardware store...

All cuts were made using a dewalt chopsaw, using a fine finish blade (lotso teeth) light pressure and copious amounts of WD-40. the saw does a pretty good job but the cut edges need filing to look good.. I got pretty good at filing
All the holes were done on a small drill press and tapped by hand.. I also got good at tapping
I did all the work myself
hope that helps

Nice work, Dionsio! Can you comment on the heat dissipation? If your design handles the standard heat dissipation, future builders could save the cost of extruded heatsinks.

FWIW, I use one of these Amana non-ferrous blades for aluminum. The triple chip and negative hook angle leave a mirror fine edge.

Nice work, Sean.

Nice to see someone finally make that style of case.
Where did you pickup the tubing and did you use any thermo grease between the tubing and sidewalls?

Thx,

Vince
