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.

The resistance to innovation on this forum is frightening.
There’s a reason for it, it’s there and real, and if you can’t hear it, fine. But please, don’t tell others they can’t, when they can, and the measurements back them up.

And you can’t refute the amount of listeners that can hear the problem with the upper mids and highs. Even the very best of manufacturers have said so, no need to paste up that list again.

Some here that have a monetary gain in Class-D and others that own them, refuse to believe that other can hear a problem.
They can keep their

Actually I can and do. Listeners having a problem with their mids and highs have a system problem not a Class D amp problem.

George,

All you do is tell others they can't be happy with Class D, and that they should be able to hear the same way you do.

The measurements you are hell bent don't back up a thing. 
There is a gap between a number and perception which you and kosst can't seem to grasp, but most can.

Best,

As Sam Elliott says "exactly right".

There's nothing wrong with being an engineer, and there's nothing wrong with taking measurements. However measurements and listening are two different items.
