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.
distortions
I said in a post that I could not hear switching distortion in my amp and believed that most, if not all, of said switching distortion wasn't audible. Ralph Karsten said to me, and I quote:

"Speak for yourself, Kemo Sabi"
Also, this nonsense about caps burning up early due to the switching technology is a lame attempt to scare people in an era where fear reigns supreme. Good electrolytics last a long time. Enough of this fear mongering.

In the amps or speakers?

I think there's been a great deal of improvements in cap technology over the last 20-30 years. Low inductance, and low ESR electrolytics are a lot more common.
Maybe the question we really should be asking Kosst and George is this:
What, exactly, are the audible effects of switching distortion in a Class D amplifier, and can you give specific examples, with speakers, that you have heard this from?

Like all amps, I don't think Class D is right for every speaker, so I am open to the idea that certain speakers will perform worse than others. So, George and Kosst, ball is in your court.
Please share with us your experiences.



Best,
