Hi Dear All
I am just wondering what amp or pre/power combo would you recommend to drive these speakers, I have tried a few different amps ranging from 70-150wpc. I read an article recently and some hifi guru suggested you need 300wpc to get decent result. Is this true?
I would appreiciate some sound advise.
Regards
StephenW

Hi Colin
I am currently using Musical Fidelity Dr Thomas power amp (125wpc with 25w Class A) with Avondale modified Musical Fidelity ''The Preamp''. Before this I was using MF The Preamp and Typhoon power amps at 150wpc bridge mode. It certainly doesnt feel that you get enough grunt there.
I have heard these speakers with the MF A280 with 200wpc and it sounded very good.
I am also in the process of trying out different interconnects as well.
Any ideals?
Regards
StephenW

I'm surprised that your MFs aren't quite up to the job, as they're in a similar class to the Aragon and Sumo ~200W stereo power amplifiers I've heard used.

Most KEFs, whatever label is on the box do tend to sound "better" with solid state units with big heatsinks and massive power supplies.

Thanks again Colin.
I have just changed my speaker cables from CableTalk Concert 2 to CableTalk 3.1(much cheaper cable) and it sound amazing, it was like a veil was lifted, everything is much clearer.
The reason I changed them was because I heard about the skin effect of the chunky cables, so I thought I gave it a try and it worked.
Any good advise on speaker cables and interconnects?
Regards
StephenW
