I quite fancy trying out some PMC OB1 speakers on eBay at the moment .... but my next speaker must be compatible with my OTL valve amps. The amps are stunning into an easy speaker load but quickly run out of puff into low impedances. Looking at the PMC specs they seem an easy load (high impedance - prolly average 10 ohms) and 87dB/W so not too bad there either (the amps can do in excess of 40wpc when they are comfy). But PMC are often teamed up with solid state muscle amps like Bryston ..... is this necessary or just marketting BS? Will the PMCs sing or squeak with my valves? :confused:
