I recently discovered T-class amps, I liked the small size and low power usage.

I bought an SMSL SA-S1 TA2020 from ebay for 34 and used an existing 12V 5A PSU.
I compared this with my Cambridge Audio A1 MK3 SE, I couldn't notice any drop in sound quality.

I was tempted by the more powerful TA2021, but all the reviews said the TA2020 sounded better.

It's connected to a Marantz CD-67SE and Mordaunt Short Avant 902i speakers, the volume and bass is amazing for the size of the amplifier. The 89db sensitivity of my speakers probably makes a difference with regards to volume.

I'm impressed!

BTW anyone know if it's safe to bi-wire using a single TA2020 amp?
I know I'll need to connect two cables into each banana plug.

Just wondering if it would make any difference on a low power amp like this?

I'm still in the process of buring it in and balancing out my sys..... adjusting my sub and EQ, etc.
However, so far , I really like this amp.

In a few days, I wiil relate my full thoughts/opinions on it.

Regarding support you can really forget Hlly. So you can generally hope that everything is O.K. with a Tripath amp when bought from a chinese dealer. About Topping's service I cannot say something because never bought an amp from this brand. Only heard and read from people that the Tp 60 is a good sounding and powerful Tripath.
I have owned more than one Topping and never had any quality issues. Photos of the interior reveal quality components and assembly. As for speakers, I am using 88dB Merrill full range drivers which sound amazing. My experience has shown that full range drivers are the optimum speaker for lower wattage tripath amps while the larger tripaths have no problems with other 2- and 3-way speakers. Having said this, my Topping TP20 MK2 will drive my 1973 Klipsch Heresy I's with no problem at all.

I'm not sure bi-wiring will really be an advantage since intermodulation between drivers is most often corrected with a properly designed crossover.

Bi-wire, not only an advantage

that's fine. The TA2020 has amazing audiophile capabilities and indeed Klipsch or highsensitivity fullrange speakers should matched with it very well

Having had to retun my Topping TP-60 to PE due to massive RF inteference on the FM band, I might try the Topping TP20-MK2 next if it is determined that all TP-60s have the same problem.
I called PE today and they will test the amp and then test another PT-60 to see what the problem is reguarding the RF interference.

The PT-60 does not have any FCC compliant labels on them and PE seems to be the sole US importer of them They might not even be legal to sell in the US.

At least the PT-20 has a FCC compliant outboard PS.
