Comparing Class T Amps

I've just bought my second Mini-T amp, this one a model SA-S3 from SMSL based on the Tripath TA-2021 chip. It accepts 14V DC and pushes out 13.5Wpc into 8 ohms.

The reason I bought it was to upgrade from my model SA-S1, based on the Tripath TA-2020 (they look identical) and performing desktop computer duties. Even driving the nearfield speakers by my PC monitor, I felt the lack of power far too readily and decided that a little more power wouldn't go amiss. Upgrading the voltage rail to 14V would give it a little more headroom, so I've ordered a 14V 5A SMPS (my original SA-S1 based on the TA-2020 can only accept 12V).

Now to my observation: even powered from the same 12V adapter, I think this TA-2021 based amp sounds better: a little fuller in the bass, slightly more focussed soundstage and even finer detail presentation. Have others compared these different Tripath chips and reached similar or even different conclusions? It seems that not all Mini-T amps are built equal.

Interesting Martin . Bearing in mind its limitations are you recommending this amp ? Had an Amptastic mini t and really did like it.

For nearfield use like I do here, running from my PC via a Caiman DAC into a pair of Fostex based speakers, the Mini-T is nigh-on perfect. Small, efficient, generates no heat and sounds far more transparent than it has any right to. For about £25 plus a PSU, I really can't see how it could be beaten.

Thanks Martin .

For nearfield computer use a Lepai 2020A does me. I got it because I wanted to try the 2020 chip and I must say it sounds good. For under £20 you cannot go wrong.

Temple Audio are the best I've heard. They use Analogue Devices chip though.

What is the type of Fostex speakers Martin ?
Had been looking at the 126En as a possible kit build as a second system, but not sure whether a T would be enough.

Fostex FF125WK.

Cheers Martin, I forgot, now recollect reading that, case from Moldova, very nice.... Some further research needed my end I think...

I've just bought one for a silly sub £12, albeit minus a PSU.
