Speakers for 11 watts Tube Amp

I don't have a specific recommendation, but efficiency is one of the few numbers with speakers that actually means something. I would look for speakers in the 90's.

 

I'm running Omega Monitor 7s and cannot recommend them enough...fantastic speakers with great soundstage. They do take some time to break in and will sound shrill at first, then again I was using Rega 1 speakers which are a little bit on the dark side. I'm using a Decware 6 watt amp to drive them. I've also added an Omega sub and that has completed my system to the point I have no need to upgrade. My room is small but treated.

Louis @ Omega is a good guy and can help with your buying decision.
