suggest tube amp wattage for my speakers..?

thx for all the responses and links friends, from what i am reading here if i understand correctly i should be looking at driving 20-25w into these loudspeakers, yes?

Beavis, when you said "87dB sensitivity isn't very great. Recommend sticking with a larger push-pull amp.", are you saying that these loudpseakers are not appropriate for use w/ tube amplifiers at all? i should mention this setup is only for my home office, and will not be driven too loudly nor is it meant to serve more than casual personal use... i will be feeding the system w/ balanced audio output from my computers, into a tube preamplifier.

i should also mention, i do not have these loudspeakers yet, they are being built and are on their way in a couple of weeks... thx once again for all the input friends, and have a wonderful day..!

hi Gumbei, thx once again for your reply. i'm afraid my lack of knowledge and experience is going to start becoming more and more apparent w/ every post, i am reading up on what to me is unfamiliar terminology (impedance curve, sensitivity rating, etc.)... my experience w/ audio equipment is fairly limited, and all from the solid-state world, i have a Linn 51xx setup for my home theatre.

on a recent business trip i had the opportunity to hear a tube-based system for the first time at a clients house, he had a small setup in his office made up of a pair of Linn Katan loudspeakers and monoblock 'Dared' (?) monoblock amplifiers... while i don't know the specifics of his setup aside from the above, he did mention that none of it was anything too pricey, as far as audiophile equipment goes. now the sound produced however, i will admit, i was just stunned.

the sounds had such a rich tone and warm quality, so very different from the digitized hard-edged tones i am used to hearing from audio equipment. i decided i wanted to do the same thing and enjoy such wonderful output in my home office as well... i apologize for my absolute lack of 'snap' when it comes to this subject, i will be doing more reading to try to get a handle on what kind of units i should go w/, and if anyone can offer any other general input on what sort of monoblocks i might be wanting to look at for my soon-to-arrive RBHsound 61-SE's would be great, even if it were just loosely suggested specs as far as wattage, or any factor that should be important when making such a selection.

i should add, i'm looking to keep the amplifier purchases somewhere under the $2000 USD mark, for what its worth... thx again all..!

Beavis, thx a bunch for your reply and all the great information... more reading for me this evening it seems!

so, i take it from your response regarding my listening location distance (1m tops) that i don't need to worry too much about wattage overhead then? would i be fairly safe in assuming that amplifiers that output 20w will work out ok for this scenario? i also see many units that are rated at 16w output, considering my listening distance would these perhaps be sufficient as well, or should i err on the side of caution of assume it would be better to have too much wattage instead of too little?

i will also do as you suggest and contact RBHsound directly to ask about recommended wattage for these particular models (61-SE) and see what kind of input they can provide...

thx again for all your help friends, its nice to not get slammed on a public web forum for a lack of knowledge, and rare in my experience..!
