i am using topping tp20 mk2 (with ta2020 chip) with alpair 7s in a sealed 6.2litres box on my desktop. Its still in the burn in stage (phase 2). Havent gone beyond 10 o'clock yet. In my small 10x12 room, its enough for nearfield and sounds really good. Once the break in is done, I will crank it up and see how it does.

I had the pleasure of hearing a tripath based Sure amp, a nice tube amp, and a gainclone on my full range speakers (Markaudio Alpair 10.2). I quickly preferred the gainclone. It just sounded better, fuller, more instrument separation, etc. Synergy is everything and if possible it's great to invite some friends over to your house with their amps in hand to see what works best for your particular setup.

The Temple is nice (great review at TNT BTW) but the TAMP-90 just seems to be better build. Just look at the size of the ring transformer:

Properly implemented Tripath designs are amazing with fullrange speakers. Synergy and more magic.

I'd personally take a 24V powered amp with speakers of that low sensitivity. If you want ready-built then have a look at the Hifimediy TK2050 or Arjen Helder TK2050 amps.

Regarding power supply. Which 24 volt options are available? I cant find any good 24 volt options on the web.

1) battery, or can i brigde 2x12 volt?
2) smps
3) linear diy kits

Mean Well make really good ~24V switching supplies. There are some good examples mentioned in a few threads over at the Class-D forums.

You can very well use batteries. I recommend LFP / LiFePO4 batteries. These are available in the US at BatterySpace.com/AA Portable Power Corp. Tel: 510-525-2328 - Powerizer Battery Official Site - I'm not sure about Europe.

And a linear supply can also be built 41hz.com sell suitable DIY supplies with regulators and rectifiers - check out their PSU1 series: 41Hz Audio:PSU1-PS (Power Supply) kit or PS3: 41Hz Audio:PS3, 60V Power supply kit

There are lots of options. The Mean Well route is probably the most plug-and-play.

I'm pretty sure they're still doing them. Hifimediy T1 throught T4 are TK2050-based. They do use newer and better power stage chips (output transistors); These are half of the chipset. Still a TK2050-based design.
