Moving away from inefficient/low impedance speaker in order to move to a Tube Amp

It has been said over and over on hundreds of posts. It is the old horse power vs torque argument in engines. Watts per channel is only a small factor in the overall power of an amp. You can buy an amp with 500 wats per channel that has no power and you can buy an amp with 5 watts per channel that has tons of power. Do the research and reach out to the companies to break down the amps total package and specs. In todays world you might even be able to contact the designer and ask them to define your solution.

I used Primaluna 36 watts to drive 88bd Salk Songtowers with great ease.Then traded up to 70watt Primaluna Evo 400 and found it didn't really make much difference in the ability to drive the Salks but sounded better.

Then I bought 93bd Tannoy Turnberry GR and that made a big difference in detail. All these subtleties came through.Will never again buy a speaker of even average efficiency.

Thanks...the system will be a second floor bedroom, that is around 19 X 15, with standard 8 ft ceilings.

In a bedroom system your speakers will be fine if you have the space unless you really plan to blast. I would think an amp with 15-20 watts would be plenty. You might want to add a sub just to handle 50Hz and down.

If you get something like the ZU Omens I would expect that in a bedroom you could do well with an amp of only 5 watts per channel.

Bedrooms for the most part simply don't need to play all that loud.

I have read over and over again how important it is to purchase high efficient speakers.  Why bog things down with a low impedance speaker?

I wonder what people think of either then Revel Performa's and the Paradigm Persona 3 speakers?  I did prefer the Revel's.  No one ever talks about these speakers.  Wonder why?

In a bedroom system it won't matter so much.
