The new LM4780 board is exactly the same as the Premium version that was described here: http://www.diyaudio.com/forums/showt...565#post636565

Premium boards (clear mask, gold plating) are available as well and no discounts are available.

Check it out. Thanks for all your help

Comments, questions, advice...welcome! Other pics here on audiocircle:

This is an incredibly well made piece of equipment, with a lot of attention to detail. If I can suggest anything, you may bapass the input coupling caps if your source or HagUSB board allows it.

Also, what is your primary source? If it's CD player, you may still simplify the way the inputs are wired.

Peter,

Thanks, that's a great compliment coming from you as your enclosures are really, really cool.

I was thinking about removing the polystyrene caps like you recommend. And I was also thinking about using some VH Audio or Mundorf Silver in Oil caps on the output but the unit sounds so good already...My source currently is a modified Philips 963SA as a transport. I'm moving up to a Squeezebox/Computer USB territory in the near future.

I'm sure your NOS design will complement it quite well.

Thanks for the design,

Anand.

The DAC has been available for the last two years. The thing is, I don't really advertise it much and all sales have been generated by a small info entry in May18th Latest News on my site: http://www.audiosector.com/ and couple reviews from 6moons with the latest one posted here: http://www.6moons.com/audioreviews/a...e5/system.html

Few months back, I redesigned the original board, since DIP version of CS8412 receiver is not available any longer in large quantities. The board now accepts only SMD receiver version, and the layout has been slightly improved. The current price is $230 for Premium kit. Hammond transformer is additional $30 (including PCB mount fuse and power entry module), Cardas dual RCA adds another $20. International shipping is $25 (with transformer), $12 without.

I think this page needs some updating. Or at least some new information about the kits and other products.
