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,

Zu is special  hate  and love product. Some say too harsh and thin,
Some is best product ever been made. 
I belong to first group 
Anyone buying Heresy IIIs should look around for a REL sub, as I've found these to match really well with these (and other) speakers, and in the last few years found a couple of great used RELs for a couple hundred bucks each. 
I heard the Zu's with jazz funk being played at a show, and they did not sound at all convincing to my ears. They were on the longer wall in the room at the show, so maybe not the best or Ideal position for them?. *If all you listen to is the human voice and Gregorian Chant then more power to your elbow.   *smiley face.........
Seriously though, well respected UK hi-fi reviewer Jimmy Hughes for
HI-Fi +?  reviewed them with great enthusiasm with a very complimentary review, he liked the Klipsch sub (12") woofer he was using to add musical depth with the III's also.....
I missed out on a local sale of a virtually new pair  of III's going for $1000.
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 ??????????
