Can anyone give me their opinions on the above loudspeakers, in particular, what amplifiers do they work well with?

I've heard SA loudspeakers briefly (I think they were SA 1750's or 1280's ) and liked the sound, but it's impossible to get a proper demo in the UK.

PS. Many apologies for posting to this site in English.

Hi Howard.

The SA's are a light load for the amp, so you can use pretty much any kind.
 - however, the better the amp, the better the result

I've listened to different SA's on rather expensive setups, and they are able to "keep up" with amps/CD's who cost alot more than the speakers. 

I own a pair of 1280's myself and I'm very happy with the sound, wich can be described as very dynamic with plenty of attack and speed.

Bass is the speakers weakness, but after experimenting with different amounts of sand in the sandchamber, I achieved satisfaction.
