Hi Banana,
Thank you for your comments. Here is what I have to add.
<>BTW, what kind of circuit are you using? I'm interestedOK. This is the interesting part. This circuit is built here in Montreal by a friend that has over 30 years of experience in the audio field. He personnaly knows the owners (see inventors) of companies like Sim Audio, Classé, Totem and Tenor Audio and has sometimes helped or commented on their project (some of them are now on the market). This guy has been building amps for more than a decade. I listenned to some of them, they are incredibly musical and...they sound true.
The circuits I will use are his. I don't have a great knowledge of DIY and that's why he'll help/supevised me. Here are some details of the board:
Bipolar board with 4 outputs per channel mounted directly on board, working in class AB, Running at +- 64V, Teflon OFC 4 onces (like in big Levinson) board with a dielectric of +- 2, trace fully balanced, impedance fully balanced, heatsink and output transistors mounted directly on board so it is fully operationnal even without a chassis, each electrolytic can is bypass by a prolypolen cap (Solen for now) directly on board.<>When I was building my first diy stuff, I also looked around for exotic components and wondered how they would sound. Later I learned that the circuit itself and the grounding affect the sound much more than the power supply components.
I am not looking for exotic stuff but just trying to have tips to maximise my efforts with the components I have. Of course, I will be tweaking and tunning the amp for a year or two (and might change some components along the way). Anyway, it's all about system synergy and more than everything the final product will have to be pleasant to my ears. BTW, could you comment more on the grounding effect ? What are your tips and experiences ?<>To avoid wasting money. I suggest you finish your prototype first, and then upgrade the components bit by bit.
Money was spent this way: 600$ US (1000$ CAN) for the Plitron LONO transformers (2 at 1KVa ), another 600$ US (1000$ CAN) for the boards, wiring and components and 300$ US for the all-around 5/16 '' thick chassis, machining and anodizing.
Best regards,
Marc-André Rodrigue
