Class T vs. Class D Digital Amps


Hi folks. I'd love to hear some people weigh in with a layman's description/comparison of these two technologies. I'm particularly interested in how Channel Island's Class D amps might compare to Audio Research's Class T gear.

How do these technologies compare? How does the use of these technologies alter other aspects of amplifier design like power supplies, transformers, etc.? What are some limitations to using this technology for amplification? Other than efficiency and cool operating temps, what are some other benefits here? Anyone think this is the wrong direction to be going?

I love my tripath amps. I have sampled quite a few. For what they typically cost anywhere from $25.00 up to $1,000.00 in my opinion nothing comes close. Of course certain parameters have to be met in order to acheive emotionally engaging music. For one use sensitive speakers. I use Fostex FE103E and Fostex FE127E, no crossovers or filters, not even a notch filter. No tweeters. Just a good modified M&K VX-4 passive subwoofer. The sound is just like live. The music flows and the artist placement whether it be a musician or a band can easily be perceived. Drums in the back of the vocalist instead of in front like most speakers and tube or SS configurations. Also use a tube buffer between the amp and source. This takes away that dry sound and replaces it with a tube coherance that makes the music flow. I love the DIY Paradise Charlize with the hollow core inductors. Of couurse the Art Taylor Ampbox is also very good. As is any of the highly acclaimed Redwine products but be prepared to spend a little coin there. I usually make my own speakers and have had exceptional results although any Fostex designed speakers will do, as will Audio Nirvanna or Coral Flat fives. And don't let me forget opt for the Sealed Lead Acid Battery mod. It is a pain in the butt to remember to recharge but the reward is in the blackness of the completely quiet backround from which your music blossoms.
