In need high-efficency speakers


I recently purchased a preowned Mystere IA-11 40 watt tube integrated amp to replace a 120 wpc SS amp. Overall it has a very satisfying sound with plenty of detail, dynamics and a tight bass for a tube amp.

The problem is the combination of our large town-home living/dining room combo with my 87db DIY Seas Froy Mk3 speaker, powered by the 40 watt amp means it can’t play loud, especially a problem with movies or TV specials.

I was hoping to change to the Zu Audio Omen Mk2 or Klipsch Heresy III high-efficency speakers. My wife and I agree it is unwise to spend that kind of money with our current finances. The Zu Dirty Weekend would be a cheaper option, but the Klipsch would look better in our living room.

So I’m looking for solid advice on what to do from this audiophile community.

Here is a link to my ’Virtual System’ if that will help.

Thanks all,

Simple answers, I just wanted to go back to a tube amp and like Mystere amp. My speakers sound great w/ tube amp as well as solid state, just would like more volume in some situations.
I like Mindlessminions comment on Zu and suspected that, reading and watching youtubes vids.
I like Wolf Garcias comment on Heresy III and is what I think would be best. Will have to figure out how to buy them. Looks like I'll be having quiter sound than I'd like for a while longer.
Im not sure on Tekton. Looks interesting from a quick look. Not as efficient too. I'll have to study them some more.

Or you could try adding a powered sub and only sending frequencies above 50 to 100Hz to your mains. This would free up a lot of headroom for your current amplifier. 
I'm a Zu Omen DW owner and love 'em, but in your case I would ignore all of our blather and just buy them both.  Zu gives you 60 days in home with free returns.  Crutchfield sells Heresys and also gives you 60 days and only charges $10 for returns, so you literally have nothing to lose by getting both and sending back the loser.
