High end Class D amps?

I was looking to change mine NAD C370 (For a class D amp) who had a faulty protection circuit which is fixed and some other nearby strategic capacitors where also changed for around 50,- Euro on cost an materials. Than it occurred to me that a total revision on my NAD was only 350,- Euro to make him even sound better (probable) an will last another 25 years or so. Another thing is i run 2 sets of speakers close monitoring an far-field the integrated preamp gives me all possibilities to use one of the 2 sets with one click of a button. If i buy a class D amp i have to consider too look for a new separate preamp involving cost. Another thing to think about if something go’s wrong (as with my NAD) spare parts are cheap an are there for the foreseeable future if a high switching class D amp containing probably also specific programed firmware (wich is not free availeble for upload) stops working it is likely you can dump it with in 10 years time.
So i think we don’t have enough reliability data regarding class D amp’s but for sure regarding technolgy, low energie use an sound quality Class D amp’s are the way forward imo

snarfie. You may have a point as far as availability of parts for an aging Class D amp but honestly like everything else you won't keep it that long. Class D amps may be like computers, always evolving which could render them obsolete in ten years (maybe)) compared to the latest offerings.
For laughs I picked up the new Edge A2-300 (Swedish Made) Class D amp, I'm not laughing now. Retails for $500.00 plus shipping and kicks butt at 150 watts per channel with a refined, clear sound coupled with solid dynamics. Excellent performer!

I don't agree that today's class D can be compared to constantly evolving computers

My EVS1200 is a dual mono using IcePower As1200 modules which are highly tweaked by EVS.

See the new Stereophile review of PS Audio M1200s. As amazed as MF is, I bet they can't hold EVS jock strap

tweak1, I think your right that Class D amps are not evolving as fast as computers, but they are evolving (for the better?) that is why I emphasized maybe as a matter of opinion. Your EVS 1200 is a good example of good sound doesn't become antiquated.

I remember the first Class D amp that was successfully marketed and sold to the public, the PS Audio HCA-2 . Stereophile placed it in their Class A category and a reviewer stated that there would be many more designs to come but he doubted that any of them would sound as good as the HCA-2. Was he right?

Prior to reviewing,  I owned two PS Audio HCA-2 units. Sold them not too long after because A and A/B kicked its ass. Now, it's reversed and class D is kicking ass on other classes of amps. It's going to be carnage.
