my requirement is 30W min. into 8-ohms.
want to retain the 'sweetness' of t-amp but with higher power capability
i want to gather more reviews about TPA as i think TPAs are not as popular as t-amps

If you want to get an idea of the TPA sound quality amongst other audiophiles , including some full range owners, you can read about the TBI Millenia here which uses the TPA3100D2. The ebay options won't be as well made as the TBI but they also cost 1/10th the price.

If you want to stick with Tripath then get an Hifimediy.com amp - the designers are from diyaudio and the build quality is very high.

Or build a tube amp. Regardless, enjoy whatever amp you choose.
TPA3100D2 is specified at 20W max, while TBI millenia MG3 (as per the review) can put out 32W at 24V. so i guess this one uses higher power TPA chip like TPA3116

My current amp uses the TA2022, but this is very old technology. I'm looking into some of the newer chip. If nothing else, there will be quieter, although I don't consider this a problem with the TA2022.

my mistake!
i took look at datasheet graphs and TPA3100D2 can indeed reach to 32W but at higher THD

I stopped reading the TBI Millenia thread right after the OP said that changing the input from 1/8" to terminals increased the SQ 30%. I did read the linked review. I'd like to hear one. I think I might pick up the SMSL SA-50 and see what the TDA7492 chip sounds like. If it is noticeably better than TA2022, I'll look in to a nicer implementation.

Agree on TPA over Tripath. There are some last gen TPA3116-based boards on ebay, more power and said sounds better than 3100. Did not heard personally yet, ordered two - hard to resist for $20 )) - for kitchen etc but haven't received yet.

Said that I beleive UCD are way above them all, they are not even sound great, they measure great too ) TPA THD charts are not that promising.

Even better place to start: here. It's $10. That's it. No excuse not to try it. It's a lower power TPA (not TDA, which is from a different company) chip.

I know it's kind of pointless to even mention it because people have their biases, but again it's $10 and plenty of power for a full ranger. You will not be disappointed. These are not like Tripath, they don't have that analytical edge. I personally think they are more akin to tubes than say solid state with an outstanding midrange quality and I'm pretty sure lower noise as well. I'd be very curious to know how they rate w/ MA drivers.

Hmm gotta try these too, design matters, thanks. I'm about to order a lot of stuff from them anyway and still have same places to put an amp and a pair of boxes with say CHR-70 ) Pity they don't have volume pot like these TPA3116 boards.

Apologize to OP for hijacking the thread ))).

i found this on ebay
TPA3116 2 1 2X50W 100W Class D Amplifier Board YJ | eBay

its 2.1 amp board woth 2x50W + 100W. from datasheets, i am assuming this 100W is obtained by what they call PBTL mode (parallel-BTL) configuration.
