No, it's also a different DAC.
Free DSP: up to 384/32, 9 band PEQ, only integer gain
CDSP: up to 96/24, 5 band PEQ, allows fractional gain
I get the impression CDSP is likely the same chip, same limitations as the Tanchjim One DSP cable, that is also 96/24, 5 band PEQ, allows fractional gain.
I think there also may be some other limitations that vary between them, like I think one has a max 3dB gain, the other disallows filters over 10kHz. I haven't gone through and checked which is which. But they are definitely two different platforms.
Moondrop also made claims of 0.0008% THD+N (102dB SINAD), 120dB dynamic range and fully balanced output on the FreeDSP, and backed these up with AP555 screenshots, they made no such claims for the CDSP. CDSP sounds "fine" with no hiss or obvious problem, but it's possible the DAC on the FreeDSP is of higher quality, with better measurements.
I haven't checked the power, will have to do that, see if they are the same or different.
The physical cable on the Free DSP is also quite a bit nicer, it's very like the
TACables Obsidian which goes for $30 on its own (a bit cheaper here in Asia- but it is a "nice" cable).
