[QUOTE="Nidri, post: 64812, member: 1342"] Here's a practical example, which, if some of the forum's more knowledgeable members could comment on, might shed some light on the subject. I have a pair of Dynaudio Audience 52s, with a rated sensitivity of 86dB, which I believe is quite low. The nominal impedance is listed as 4 ohms. Currently I've got two amps on hand : 1. A Valve Audio Exclame 100, rated at 100wpc/8ohms. 2. A Xindak MT-1 EL84-based valve amp, rated at 12.5wpc/8ohms. ( I don't have any figures for the wpc figure into 4ohms for either amp, unfortunately. ) The reach a subjectively equivalent volume level (also the level at which I like to listen to music), the Exclame's volume control sits at about 9 o'clock, whilst the Xindak's sits at about 12. So clearly the Exclame is the more 'powerful' of the two amps, other considerations aside. What are the implications of this? Are the Dynaudios 'too big' for the Xindak, i.e. is it less than ideal to have to run an amp at the 12 o'clock position for extended periods of time, i.e. should an amp generally stay in the 9:00 to 10:30AM region? On the other hand it does feel that the Exclame is kind of 'wasted', like it doesn't have a lot to do, as if it's hardly breaking a sweat. Sure it's great to have all that juice on tap, but if you never use it... Nidri [/QUOTE]
