In Reply to: Good amp for Kef 104.2 posted by jazzbeat on January 1, 2017 at 17:30:08:
The 104.2 was designed to provide an ideal 4 ohm load for amplifiers. It is very easy to drive and just about any amp will work ( subject to the owner's preference for any particular flavour of SQ of course). KEF quote a minimum of 25 wpc into 4 ohms but I have read of satisfactory use with an 8 wpc tube amp. Of course room size is also a factor and as this was a British owner I imagine a smallish room.The main problems with this vintage speaker seem to be that the foam drive unit surrounds decay and the ferrofluid in the tweeter dries out.
So very large power amps (over 100 wpc into 8 ohms, that being the usual impedence quoted in specs) are not required and would not have been readily available in the speaker's home country when the speaker was manufactured. Over here they would often have been paired with a Quad 405 which would have been considered high powered in the UK back then though I do not offer that as a recommendation necessarily.
