Just want to say that I spent more time listening to the 'really-damn-hot-rod' (or maybe 'hell-rod'?) last night. It just sounds better to my ears. Much better. Although I did change the output resistors down to 470, the difference in overall clarity, smoothness, etc. was not heard in the 220R or 1k. So unless I luckily hit some sort of sweet spot, the improvement is worth the extra heat. Hope someone else gives it a go to compare.

Its not your imagination. That is why we aimed Blue will be more ready for extreme sports users.

Ahhh. Speaking of which, is the fact that I only have 2x4700uf - versus the 4x on the Blue Board - an issue with this mod?

There is strong PSRR and stability in the regs, filtering not an issue as such. Its some users unavoidably will want it all out and far out so its good to be able to experiment with more filtering and TO-220 diode types because there will be anti polar bear energy consumption policies most likely.

Hi Salas
Am I right using this for matching Led's with 1K at Vout ?

Thanks
