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.

assuming the are the same George who reviewed the Hattor passive pre with a Nord
Sorry you need to do your homework there sunshine, you've got the wrong George I'm afraid on that one.


I'm fine with it if you don't like class D for whatever reasons, just don't tell me it is garbage
No one said it was garbage, I said it doesn't compete with hiend linear amps "yet"!!, one day it will with the likes of the Technics SE-R1 and the Merrill Element 118 now using the new GaN technology that it needs to be rid of it's achilles heel to  get there.

Cheers George

George has sided with the lack of.
Really??? And the only semi pro for it is Jeff Rowland, who makes them, wonder why??

Geez the guy who knows how to make good ones that have been successful likes them and the ones that don’t and make other stuff that must compete are not sold. What a shocker! Why is your name not in that article George?

Oh and the guy who has done it successfully is only a "semi pro".  

I’m sure when you come out with your own Class D amp someday it will be the bees knees but threads like this might convince me to turn in my audiophile card sooner rather than later and I will surely miss out.

Semi "for it" because of his statement. (forest and trees mapman)

Thanks for the link George. Seems like I may be a little more picky than the folks mentioned on that thread. For me that is.

As I have mentioned before I, first of all, don’t like the sound of amps crammed into over built chassis, they sound to constricted (congested) to me. I also don’t like the sound of huge transformers too close to the other parts hosting the signal. I don’t like the way heatsinks distort and the list goes on. In general I don’t enjoy big heavy amps, of any type. I also don’t like listening to crossovers or damped speakers or garden hose wire.

What I do like is low mass and variably tunable products. Since I use my systems as musical instruments, including the environment, I can see where my views may differ from others here. I can also see where my views might fit into the future of amps more than some here.

I really only have two beefs on this forum and neither has to do with what someone likes or believes. My two beefs are internet trolls and folks who talk about stuff they haven't actually done.
