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 trolls have infiltrated this forum now. Too bad. It maybe shut down soon by moderators. Happens all over audiogon forums.
They have always been here , just seem to be getting more vociferous of late.
This thread is under review and can possibly be closed if the subject does not remain on topic. 
My system retails for over $24,000.

 I have friends whose systems retail over $300,000.

I've been to CES and the Rocky Mountain Audio Fest numerous times.

That said, the only time in my life that I've ever actually been physically moved to tears while listening to music was through my iPod.

All this talk about amplifier technology is BS. Just shut up and listen to the music and enjoy it.


The title of the thread is The Future Of Audio Amplification.

The future is here now. It includes efficient toplogies that waste little energy as heat to drive loudspeakers. The future may improve from the current 85% to 95% or higher, but will certainly not incorporate far less-efficient designs such as Class A/AB.

Yesterday I visited a friend’s house after I was invited to check out his new TV. The price tag was staggering, less than $800.00. The picture was gorgeous and I could stand way off to the side without any distortion (or very little). 72" screen I think he said, or was it 65", anyway it was big.

We started talking about screens and price tags only a couple years back. Audio of course came up as he owns one of my systems and we talked about how audio has made huge changes as well. A little over a year ago he dumped his big high end system for my simple designing and the improvement was not small. In fact just one of his components paid for his whole new setup including his home theatre. He has made the comment, more then once, of how listening has become so less expensive then a few short years ago.

Sometimes when I read here, it feels like the guy hanging on to his old tube 32" tv weighing back breaking amounts, that no one wants to help him remove, and he can barely give it away. The mentality behind hanging on to the heavy tv is very similar what HEA is going through today. Huge space heaters taking up floor space are going to continue to decrease no matter how much sentimental value our generation places on the good ole days of plug and play.

In the future there is still going to be dedicated rooms, especially outside of the US where they take the time to dedicate and aren’t trying to living room-ize their audio system (which never really made sense). Here in the US though the path is clear and will remain steady on it’s course.

Also let me say this. Picture yourselves being 25 years old now, in todays world. Your dedicated room is going to be a lot different from the way it was way back when. There are more dedicated rooms now then back when we were doing our thing. The major difference is, now they are called "dedicated gaming rooms". I have no doubt listening rooms are on the rise. But this is different from equipment collection rooms.
