for 175$ this one should have a case of its own... right?
Triple ground, dual channels - that's a little out of my very limited understanding on EE. But cmoyBB is one of the most impressive cmoy I have ever heard and I am sure this one will be equally impressive. Looking forward for the day of release
Nice! Triple ground means that it will have separate ground per channel and 1 global ground. It guess the channel ground (noisy one) will be filtered to ensure the signal integrity.
Dual channels means it will use 2 completely separate channel (2 opamps).
How much power, I wonder?
Triple grounds would normally indicate separate grounds for each opamp channel. However, that's impossible without XLR connectors, as the ground of the L and R signals are joined in 1/8" and 1/4" stereo cables.
To clear up the non-standard terminology used in the blog article, C421 uses an active ground configuration. The innovation is in the power circuitry. We're using successive references in the power stage to accomplish two tasks:
1) Minimize noise
2) Allow the amplifier to be used while charging from USB
This information has been added to the announcement.
The first C421 prototype enclosure is scheduled to arrive in 5 days. It's a crude plastic model intended to verify fit, so we probably will not post pictures until the aluminum cases arrive.
Plenty! C421 supplies 14V to the opamps. Not a power measurement, I know...
Is the active balanced ground similar to the Stepdance?
BTW, the CmoyBB is a great little amp with no noise at all with my ES3X.
I think I like it more than the Headsix.
I'm really wanting one of those CmoyBBs but am kinda strapped for cash, will get one soon though. Hopefully those modded ones that JDS is selling on eBay won't all be gone by the beginning of July
