The Future of Audio Amplification

I have recently paired an Audio Research DS225 Class D amplifier with an Audio Research tube preamplifier (SP8 mkii). I cannot believe how wonderful and lifelike my music sounds. The DS225 replaced an Audio Research SD135 Class AB amplifier. Perhaps the SD135 is just not as good as some of the better quality amps that are out there, but it got me thinking that amazingly wonderful sonance can be achieved with a tubed pre and Class D amp. I have a hunch that as more people experience this combination, it will likely catch on and become the future path of many, if not most audiophile systems. It is interesting that Audio Research has been at the forefront of this development.

good Class D is better than several Class A amps.

Maybe against backyard junkers.

It’s not yet, only in the bass. But soon hopefully maybe everywhere.

We have achieved a major scientific breakthrough. Audiogon managed to hook this website up to 1982 and found this:

Eric you've tried numerous threads to get this Class-D "praising thing" on a roll, never to keep going, because of the "non acceptance" by way too many for you to counter.
  
Give it up be happy with yours, that you say you can't hear any problems with it.
And let those that can, and have been down that path  go the way they want.

The only ones that are really backing you, are manufacturers that are making, going to make, or selling them in retail supply, they all have a monitory interest in doing so. 
  
It almost sounds like sometimes you asking for acceptance for owning Class-D and listening to it. 

I've always said Class-D will be the top dog one day, just not yet, all the detractors (designers and audiophiles) of it have the same common complaint, it's the upper/mids and highs that are the problem, never the bass, this is a done deal showing where it needs to improve.

I would say it's the other way around, Erik has proven his case while George has failed to do so. Erik has sided with experience while George has sided with the lack of. Erik is being open minded while George is not.
