Is there anything else we should think about?

David - look at pic

put one blob of thermal grease between two BC critters in input CCS and tie them with something .........plastic zip thingie or whatever ;
they must be tight coupled, because these two have opposite tempco...that way you'll have rock solid CCS and less variation in output offset

Thank you very much for yours and Chokys work on the babbelfish.

The boards are truly beautiful and Chokys support is outstanding..


Startup is scheduled to tuesday... The last parts didn't show up in the mail today :(

Thank you too, for nice words and works...

Choky and me just want to share thousands hours and dollars spended on audio and music equipment, with other similar enthusiasts.

Wi don't like make too complicated and expensive units, but simple and more then 'good enough' (like Choky said).
Game about creation audio units is similar for me like seducing a woman... :Popworm:
...you never know what's will be happen :headbash:

So, just go ahead friend!!! :wave:

Sound impressions.... :D:D:D

It's a biiiig leap from the Aleph30 i used before.. The top end is just unreal... But what I didn't expect was the massive bottom end.. :D:D:D

I could not be happier... This is by far the best I have heard in my system.. I have previous have buildt Chip amp, Mini-A, Aleph30.

Thanks Zen Mod and Oly for the support and for making this possible.
Thanks Steenoe and cviller for inspiration.
