You can figure out your minimum power needs by remembering that you double the power for each 3db gain in loudness. So the 91db sensitivity at one watt needs 2 watts for 94, 4 for 97db and so fourth. This gives the MINIMUM required, which is not necessarily the ideal power but is a rough guide. I doubt if you would need 75 with your current speakers but if you intend to change it can't hurt to get a larger amp as long as it is of the same quality.
Next step: tube pre or tube power amp?
I own a Rotel pre/pro RSP-985 SS preamp and a matching Rotel 120 watt power amp. If I wanted to move into tubes, would I get better mileage out of a tube pre or tube power amp?
I love the convenience of the rotel preamp (remote, built in DACS etc) but I understand that a tube pre will have more impact than just a tube power amp. Is this correct?
Also, my speakers are 91db efficient. What wattage tube power amp would I need to drive them to medium/loud levels?
thanks
