Gents,I have been kicking a ton of ideas around for a nice linear power supply for the SB3. My immediate thoughts are shunt regulation. So there are a couple ideas:
1) Cajole, pull, beg, cry in front of Dave Davenport to come up with a minimal reactance power supply for the SB3 (~5V at 2A). I only see him going for it if there is enough interest, and I think there is really only one person that's interested, and that's me!
2) Use Peter Daniels Universal Power supply board which uses Jensen 4 poles in a pi filter format, then plug that into a Paul Hynes shunt regulated power supply which will spit out 5V at 2A easily. Definitely more expensive than option 1 however.But...Both options should compete with an all battery PS (like the $$$$ Optima Reds) and be cheaper and more user friendly.
I'm also reconsidering the PaceCar given the ASRC implementation of the RAKK dac II. I figure it will only be icing on the cake, given the icing is $1500!
So it looks like for a RAKK dac Mk II + Minimal Reactance 12V supply+Active output stage w/onboard dual mono minimal reactance supplies, the minimum investment is about $1200. I'm expecting to spend about $2K in total, to accomodate a chassis, remote volume control, I/O connections, etc...then another $500 will accomodate an SB3 with a shunt regulated supply.
For about $2500, this should be about as far as I will go with digital...for now, hehe.
Anand.
