TRADED
First of All: Silicon Arts Design is the solid state wing of Concert Fidelity. The Si2 is low-wattage purist combo, meant to largely match the singled-ended tube amps from Concert Fidelity.
I sold my single-driver speakers, and no longer have a good use for this little pair. The preamp has zero gain, and a very good electronic volume control. The power amp is rated at 10wpc into 8 Ohms and18wpc into 4 Ohms. It has pretty much a SET sound. The stock power supplies are surprisingly good--I actually prefer them to my battery power supply.
I'm also including the cables, a 0.5-m and 1-m pair, that came with the Si2. The Si2 don't seem fussy about cables, as long as you keep the cable lengths short.
Here's a review I found:

--a good quality power conditioner (Isotek, Shunyata, etc.)
--small to medium sized subwoofer (e.g., REL)
--good power cable (e.g., Shunyata. No DIY.)
--acoustical treatments, especially small ones
