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,

I had some GoldenEar’s for awhile and you know what they were great speakers. I foolishly thought they weren’t audiophiley enough at the time. Meaning they just didn’t seem cool enough, dumb I know. But they imaged big, great tone on em. I listened to a lot of jazz with them. Should have tried to wring more out. 
After 2 of the OPs posts where he did not tell what his budget is, then scrolling through ALL the replies, I did not see anyone ask his budget ??????????
I didn't think it was necessary, because I was interested in Klipsch Heresy III or Zu Omen 2, and even Zu DW2. 
Thanks Fourwinds
GoldenEar looks nice but a bit lower efficiency than I wanted.

Jayctoy,
I've looked at Omegas, look interesting. Wonder how they sound compared to Zu?
I second jayctoy, omega speakers are very musical and would be a great choice!
