[QUOTE="Bruce M, post: 859741, member: 20147"] Wonderbob is looking for sensitive speakers for a lower power valve amp. The Bentley, Boston and Proac's are all 89 dB? From the little bit of "research" I did, anything less that 90 dB is not really sensitive enough for low power valve applications. bbe22's suggestion is interesting, those are 95 and 98 dB. The Klipsch R15m is 94. The Klipsch R24f Judy suggested is 95. I think the Monitor Audio Silver range is also quite high. These Castle Knight 2's are 90 dB and have decent reviews, also nice low frequency response for a bookshelf: https://www.avforums.co.za/index.php/topic,71780.0.html 1 dB difference doesn't sound like much but it's a log scale, so a 3 dB deference is something like double the efficiency/sensitivity. i.e. half the power required to achieve the same "loudness". Or something to that effect.... Of course, all the numbers above are claimed by the manufacturers, so who knows really? Wonderbob, what sort of output is your Mars amp? [/QUOTE]
