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?

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:

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

Tech Hifi brings back so many memories of my teenage years. I used to love looking at their brochures of systems and listening to gear.  At 15 years old I saved all I could on my first job and purchased my first system at Tech.  I still remember what I purchased!

Micro Accoustics speakers with tweeter array 
Technics integrated amp with meters
Kenwood KT series tuner
Micro Seiki turntable 
radio shack wire 
I used to covet the Micro Seiki tables but they were out of my price range back then. I settled for a very nice affordable and snazzy Philips 312.

My system I bought while there (dorm room sized) was Hitachi 802 Class G receiver, Phillps 312 table, Grado cart, Aiwa AD6550 cassette deck ( I loved that sexy beast), and OHM L speakers. Still have the OHM Ls that I’ve maintained and upgraded myself since. They can still compete and sound better than ever with my Class D amps.

I upgraded to a Tandberg tr2080 receiver I also coveted while at tech a couple years later bought at Leonard Radio on Route 17 in paramus NJ, a wonderful local shop  at the time.
The Ohm F's were the dream speaker at Tech. I listened to them often dreaming of having a set. Yes, they are still fantastic...
Such an interesting discussion!

I'm perhaps a month into my Class D audition and I am very pleased.  I agree with other posters that the goal is good sound and comparing my new Bel Canto ref600ms to my Supernait 2....well, it's not even close - the Bel Cantos are better in so many ways - dynamics, speed (yes, even against the PRaT Naim) and in particular imaging.  The bass is excellent with so much more control and I find the mid/hi excellent as well.  No ear ringing here!  

I'm still comparing and learning - but I suspect soon my Supernait 2 will bo going to the 'Gon.  

Since I am having fun exploring I may try to pick up a Class A or A/B to power mid/highs and keep the D's for the bass to bi-amp. 

All in all, have to agree with mapman.  I could live with this setup indefinitely - incredible sound more than anything.  The benefits of small size and efficiency are just frosting on the cake.  I'm tempted to find a Bel Canto 3.7 or similar preamp/dac to simplify my rig and save some $$$.  As always, it will depend on the sound!
