Hi,
I recently jumped on the opportunity to buy a pair of KEF reference 5 second hand at a good discount. Specs recommend an amplifier between 50W and 400W (cf specs). I already had a Mark Levinson 5805, rated at 125W under 8 ohms and almost double under 4 ohms (cf meas). The system is setup in a room measuring (WxDxH) 20x21x22, open at the back and cathedral ceiling. Often with classical music records, I turn the volume knob higher, let's say up to 50 or even 60 over 80 which is the max. I was wondering if I was under exploiting the potential of the KEF and needed a more powerful amplifier. KEF is also recommending using an amplifier providing 60% to 110% of the speakers max amp rating (cf kef blog). So I was thinking about using the Mark Levinson as a pre-amp and adding a class D power amplifier like the NCx500. But given your experience and your expertise, will it make such a big difference in terms of sound quality? Is my amplifier sometime clipping without me noticing and slowly but ultimately, it's destroying my speakers? I don't have access to a class D amp "just to try", so what's why I'm looking for your opinion.
