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'm not at all befuddled by George. He's looking at amps that overshoot and have horrible low level distortion characteristics, just like I am, and is rightly calling that a bunch of crap. JA wouldn't call any other kind of amp "good" if it had that much overshoot or low level distortion apart from some tube amps. I read the review on that Cary with the 1% distortion at 3 watts. That was a VERY forgiving review in my estimation, and the listening evaluation made it abundantly clear that the thing was most definitely acting as a tone control of sorts and departed wildly from neutral. It's ONLY saving grace is that it was entirely second order distortion. That's not what class D amps are doing. They're making a complicated .05% distortion at a fraction of a watt.
The nature of the market place makes it obvious that true high fidelity isn't what sells. Nobody is standing in the isle of a Best Buy listening for harshness on that $400 pair of Klipsch. Most people LIKE punchy, sterile sound with insanely overblown bass that sounds extremely loud on account of the distortion. 
I'm much more concerned with .05% distortion at .5 watts than I am with .005% at 150 watts. For my listening, nothing going on at those levels of power make any difference. Unless you're listening to 82dB/W/M speakers at 20 feet, those levels of power don't make any difference to you either. 

I hereby nominate Koost and George for the Negative Nelly award for incredible Class D bashing.  Who do you think will get the award?   He who repeats himself the most wins....don't you think?

We need a little humor in these times.  Trouble is these guys are serious.  To bad, life is really, really amazing.  Audio just keeps getting better and better and class D has made it more affordable and more efficient.  I just wish these guys would get out and listen to the latest and best class D amps (including those that switch at 500K and use mosfets).  Some great sound out there on the cheap.....as many have already posted here and it will just keep growing and growing.

May all be blessed in this new year!  Enjoy every moment, for you never know when your time is up.  The more you bless and serve others the more happy you and everyone become.  Love everyone, love yourself, the earth and be at peace.  God's love and joy are always present.

Ricevs, your only protecting your new Class-D baby your soon to unleash on the public, built around the Icepower Class-D modules, it’s as clear as the nose on your face. here’s a free plug, but I think it’ll end up a furphy.

ric I did not find the Audio C link you referred to. Maybe Im looking in the wrong place. I am new to the circle and cannot use the search feature

Hello Recevs, how dare you believing in your own class D creations ;) You should instead prostrate yourself and squirm in shhame, while grovelling and begging undeserved forgiveness from the righteous paperholic and Martin colloms-fearing audio morality police, which keeps us in nirvanic purity, whilst protecting us all from straying into the the anathema of visual osciloscopic abominations lurking inside non-Colloms-blessed classes of amplifier operations.


Happy New Year everyone!
