>From the hardware side the design for CSP1 is done. We are currently
waiting for some custom oscillators to be manufactured. JackOfAll is
working on the driver for the DAC chip using the SWAMP board. I don't
want to finalize the board design until we know we have drivers that
work, I don't want to find out that "oops, this pin needs to  be
inverted" after the board files have  been sent out. Between garden
variety wandboards and the SWAMP board I think we can get the software
working for everything we need. 

Those oscillators are probably going to be the gating item on getting
CSP1 hardware built. 

The test boards I've done for DAC chips, regulators etc are working
extremely well. The concept I'm working with is bypassing the internal
digital filter in the DAC chip by doing the upsampling in software on
the processor, this is turning out to sound extremely good. My original
goal for this project was to get very good sound out of this, way better
than it's price would suggest, but the results I'm getting right now
indicate this is significantly better than that, it's getting close to
the best there is. It's that good. 

Unfortunately in order to get that lofty performance might take a really
good power supply, better than the basic switcher being talked about in
this thread. After we get the real hardware built and people  using it
we will have to do some experiments with power supplies and find out
what the real sesitivities are. I'm doing quite a bit to try and cut
down on PS sensitivity, but experiments still show that the really good
supplies sound better. 

The software guys continue to improve the software side, Triode and
JackOfAll have done a phenominal job getting this all working, it's
further along now than any other project  I've ever worked on has been
at this stage. 

My personal goal is to have CSP1s built and ready to send to the beta
testers before the end of the year. I know everybody wants them
tomorrow, but that is not going to happen. 

Well I guess that is about it for now.
