At this time of the year, in Calgary, you'd best invest in a nice warm coat

+3 C today. All I need is a sweatshirt. Besides, I already have a coat and spending money on another coat won't yield a monetary investment return.

See post #18 and #20. I'm afraid listing the individual components within the BOM might be listing too much, but the site does state that the BOM costs for just populating the board is approx. $250 with Tom's recommendations.

Best,
Anand.

Cool, we go up to Blowing Rock several times a year and visit Boone as well, our favorite place in NC. Raleigh is getting really "crowded"....

Good luck with the design tom, it appears right on the money spec wise.

The documentation, including the BOM, will be provided to paying customers. The relevant chips are: OPA1611, OPA1612, LME49600. I'll add more detail on my website soon.

The total BOM cost is $250.

Tom

Nathan, who arranged a Head-Fi meet up in Winnipeg in November, was kind enough to write a very thorough review of the HP-1. He also included some of the correspondence he and I had via email about my design philosophy and my justification of the design choices made on the HP-1. You can read his review here: [Review] Neurochrome HP-1: Making sweet love to your HD650... or, "What the O2 wishes it could be"
