The Tripath things we used were the TA0105A. Each Amp contained two 'modules' each capable of well in excess of 500W.
The only limit was the PSU, which limited the entire unit to 2 * 200W
The thing we found was the TA0105A was a bit temprimental, it gets hot and was very keen on switching its self off. In the end we added a fan and took out all the power limiting !!!!

Anyone know much about the Bel Canto aproach? Someone mentioned that they sound better than the $30 Sonic Impact. It would be interesting to conpare the schematics to see why....

I don't know. It looks pretty run-of-the-mill to me:

http://www.6moons.com/audioreviews/belcanto2i/belcanto2i.html
http://www.soundstage.com/yfiles/yfiles200002.htm

The eVo 2i looks like it uses Panasonic FC caps, where the eVo 200.2 uses Nichicons (presumably the HE series?) for the filter. Both seem to use a 500VAish toroidal transformer.

I would guess that the rest is pretty similar to the tripath datasheet. Heck, they probably even specify the Panasonics on the datasheet for the bigger amps 😀

Funny 'bout that Soundstage article. I've read it before.

It’s sometime during the early ‘80s. Deep in the heart of Gaul, a small but fiercely independent group of audiophiles are the last bastion of resistance against the usurping onslaught of American-sponsored high-wattage solid-state amplification. <snip> Jean Hiraga, of Le Groupe l’Audiophile of Paris possesses his own secret brew.

I was part of that "club". Jean Hiraga taught me plenty. Great guy, real myth buster, mean amp designer. I built a few of his designs, used a pair of his Altecs for awhile, my favorite speakers. Ah, the good old days....

About the BelCanto stuff, they may be tweaking feedback, transistor bounce, V10 power supply and such. The bigger Tripath chips have a lot more "handles" than the small ones. It would be nice to know what they've done.
Odd that the Sonic Impact seems to get much better reviews. Must be the price. 😉

I think when you are spending a few dollars as opposed to a few thousand you are a little more crictical but i think what you state above is the reason we are all here....dissatisfaction with the prices and snake oil rubbish and the feeling that we can do it better and cheaper...maybe.

Possibly. Maybe they also match the components together as well.

I agree on the sonic impact. To be honest, I'm absolutely stunned that a $30 amp sounds that good. I mean, I don't have the uber high-end systems that some of the other folks have, but it still smokes all my other amps in terms of sound quality. To me, it's worth every penny, especially since we can mod 'em easily and not regret it if we screw them up!

Agreed.

A website listing Tripath products exists!

I also put up a website this year to explore Class-T amplification, and list all of the Class-T products I could identify. It is a private, non-commercial site - I just did if for fun to watch the growth of the implementation of super energy efficient, cost-effective Class-T amplifiers. Great sound & less energy consumed - something I really believe in. Note that I have a page with links for DIY-related Class-T audio.

Harrier's TripathPower Website

I'll be updating content on the tripathpower websiite over the next few weeks. I hope people here will e-mail me if you have new DIY related Class-T audio information, and I will add it to the site. I will follow the adventures of the Class-T modders here.

I have linked to this site (www.diyaudio.com) since I put the tripathpower website up.

Note to moderators: Most of the text in this post is also included my introduction posting. Some redundancy, but I felt it was appropriate - and since I just registered, you will automatically see both posts to review them.

Just add to the list the site www.autocostruire.it, where you can find a kit based on the Tripath ta2020 chip (no smd).
It can be a very good starting point if you intend to modify something ... here you have all option open before assembling the amp!
O the web it's reported to sound quite well, and I can confirm that 🙂 after my direct experience.

I'd love a thread like this on (Hypex based) UcD's as well, as Jan-Peter is very quiet about that 😀

I've found the Channel Islands Audio d-100 and d-200 use the modules... d-100 is a UcD180 monoblock amp and sells for 1599$/pair :xeye: Review in stereophile

also in specialized home cinema computers (5 channels UcD180)
