Class D Technology

So I get the obvious strengths of Class D. Efficiency, power output & running cool which allows for small form factors. I also understand the weaknesses somewhat. 1. Non-linear & lots of distortion that needs to be cleaned up with an output filter. 
So my question is, if it weren't for efficiency & power, would there be any reason to own a Class D amp? Do they beat Class A in any other categories that count for sound quality?

Them’s a lot of notes in the sound ratings at the bottom of the article!

Why would anyone with a need for monster power to drive their speakers best not consider something like this? The potential upside is huge for many.

Thanks for the link Mapman. You make a very good point and the days of 60-150 pound amps is really behind us. I would love to hear this amp on my 90db efficient speakers so hear how effortless it must sound. I may:)

Hifi sound is best when low distortion, effortless and dynamic. I experienced this as hoped in my larger room with larger speakers in particular when moved to 500w/ch Class D amps, but power and current hungry smaller monitors (more limited output in comparison) benefited similarly as well.

When I sold hifi back in 1978 (Tech Hifi), we had amps from 15 to 120w/ch available for comparison from many of the top lines of the day in a decent sized showroom.

Guess what? With any kind of decent speaker, the 120 w/ch model in a line always sounded best. Assuming realistic levels and dynamics matter. If not, or room is small, then not such a big deal.

This is a very strong vote of confidence for Pascal.

Given the power rating, the module of the D-Sonic 3/3000 is probably the Pascal X-pro2. There is also a mono version of this amp, called 3/1500M, probably based on Pascal X-Pro1. See:


http://www.d-sonic.net/products/mono/


Cost of D-Sonic 3/1500M is $1300 per chassis.... And $2600 for a pair of 1500W Pascal amps is a pretty good deal.
