Default Anyone tried an eval board from Tripath?

Hello all

After all the positive feedback for T-Amp that I've seen (haven't listened to one yet) I thought that I might as well buy one of Tripath's eval boards. Has anyone tried them? Do they rise to the T-Amp's level of quality?

Best regards,
Mr Push-Pull

I am also interested in any experiences that anyone may have had using the Tripath boards. Check out the boards at www.41hz.com They seem great and at very good prices. Does anyone hae experience with the boards from 41hz?

Take a look on the 41Hz website. There is a forum there. Under the Amp3 section I posted my impressions of a Tripath 2024 Eval board I modded to a 41Hz board I built.

I've never tried the t-amp, but I do use a ta2020 eval board. Very nice quality, but kind of a pain to get (even though I live just a few miles from Tripath). I am quite happy with the sound from this little thing. I think the 41hz boards are based on the eval layouts (could be wrong haven't looked in a while), but with better parts. If you can solder, you may find it easier to get the 41hz boards.

PSz.

Notice that all 41Hz amps are with SMD parts so you must be handy when it comes to soldering.

I think the evaluation boards are better platforms than the sonic impact without mods as they should be (mo' money!). You can get evaluation boards from profusion plc as easy as clicking on a button and that's what I did even though I live in the US. Life is too short for the US tripathetic run around.

The 41 Hz amp 3 is good if you can solder the tiny parts. Bolder Cable may be pursuaded to sell an assembled amp to you that's been all tricked out. So far, the amp 3 is better to my ears, but others swear by the TA2024 chip.

Thanks for the replies guys.
I guess what I'm really trying to find out is what class-D amp to buy: UCD, ZAP Pulse, ore one based on a Tripath chip?

I just meant that out of the box, the evaluation boards have better sound due to having higher PS and input cap values. The SI input caps value are .33uF and that results in less bass as stated by others here. The quality of the board is better as well IMO.

I didn't want to imply that the modified SI can't be as good or better than a modded evaluation board, I was only referring to stock units.

Hope that helps...
