Respected/Roger,
I haven't compared these 2 amps directly but have indirectly:
I own, and previously used a Class D Audio SDS-440 as my main amp in my system. Class D audio's owner, Tom Ross, told me my amp and the SDS-470C amp sound very similar.
I currently use a pair of D-Sonic M3-600M mono-block amps in my system. These amps use Anaview/Abletec power modules and the D-Sonic 800S amp use Pascal modules. D-Sonic's owner, Dennis Deacon, has stated the Anaview/Abletec and Pascal modules sound very similar.
So, given the above, I'll describe the differences I noticed between the CDA 440 and the D-Sonic M3-600M amps:
Both are neutral in character and have smooth but also very detailed midranges and treble. Although the CDA440 has above average bass response and dynamics, these are the 2 areas I noticed were superior with the D-Sonic M3-600 amps. D-Sonic's bass is more extended, textured and detailed. I can discern different bass instruments more easily and clearly now.
D-Sonic's dynamics are also better. I can now clearly discern volume and tonal changes on individual instruments and vocals within the sound stage while these changes are more massed through the CDA amp.
The D-Sonic's soft to loud dynamics are also strikingly improved, which is very noticeable on HT and well recorded music (usually much better on hi-resolution omputer audio FLAC files at 24bit/96khz). However, the increase in power from the CDA's 440 watts to the D-Sonic's 1,200 watts per channel may be a main cause.
These improvements are subtle but very enjoyable. You'll need to decide if bass and dynamics gains are worth the extra money. Remember, this is not a direct comparison of the amps you're considering so your mileage may vary.
In my opinion, both of your amp choices are extraordinary audio bargains, delivering excellent performance at a very reasonable price. I think you'd enjoy either one and maybe you could just let your tastes and budget decide.
Hope this helped a bit,
Tim
