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?

oh yes! I do!
every class-D power amp I have heard so far is a POS. The list is short 'cuz the ones (listed below) that I heard turned me off so much that my motivation to keep going on to hear more renditions of this technology is really low. However, I do admit that there could be a rendition of a class-D amp that might appeal to me. From the posts made by member Ar_t, it seems that his amps might be better sounding? No idea so far! So, far the verdict is that all of them are sonically less than appealing! Yes, the (short) list: Rowland Model 201, Hypex - I think that it was the UcD180 kit that was built by my DIY audio friend & Channel Is D100.
My reason for not being drawn into these class-D amps' sound is that they produce great sound but very little music. They have all the audiophile qualities - transparency, great bass, high frequency extension to name a few but the program material played thru them does not sound like music i.e. there is hardly any soul to the music. Listening thru these class-D amps is not an emotional experience, which a requirement for me. The word "dry" comes to mind. All the above mentioned audiophile attributes are a means to an end, which is to render the music so that it is an emotional experience; otherwise, they just remain as bullet items/adjectives on a sheet of paper. Of, course IMHO. YMMV.
Just because you don't like them...........

Let me say this: if you want emotions, get a girl friend. [joke]

OK, "emotion" is not the forte of Class D amps. They aren't for everyone. You may like them, you may not. I'm not going to apologise for making them.

(Before you ask.....no, I don't have a girl friend, and I could care less about "emotion" in my music. I just want something that I can listen to without wanting running for the ketoprofen after listening to it. I hope Albert Porter isn't reading this.)

Class T is the marketing gibberish that Tripath uses to describe their technology. Tried them, did not like them. Engineering-wise. They may be better by now.
