I thought I'd start a thread dedicated to the new headphone amp design by Tom Christiansen (Neurochrome). This can be ordered pre-built, or as a partial-DIY project where Neurochrome supplies the PCB, chassis, and BOM list. I'd caught wind of this amp a while back, and preordered the PCB from Neurochrome before manufacturing had completed. Now that Tom has notified me that boards are shipping imminently, I thought I'd get this thread started.
Full specs for the Neurochrome HP-1 are available here. Tom seems to have set out to produce the ultimate "wire with gain" in the HP-1, delivering 3W/20Ω, 450mW/300Ω @ 0.000032% THD! He's using the OPA1612 differential receiver and LME49600 output stage in a loop with an OPA1611.
I've never heard this headphone amp, so am taking a flier on it based solely on my admiration for Tom's circuit design skills. It has also been quite a long while since I've done any SMD soldering, so it'll be a fun project. I'll post some pics of the build as I go and listening impressions at project completion. Meanwhile, my box o' Mouser BOM parts is ready to go!
BTW, this proto unit built by Tom is also going to be making the rounds in the US among some hobbyists. And it has been auditioned up in Canada at a local Head-Fi meet, from what I understand:
