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,

P.S:  I see that you also have a FiiO D-3 DAC.  Its maximum output rating is 1.6 volts, which is only about 2 db less than that of the Yamaha.  So what I said in my previous post with respect to the Yamaha is essentially applicable to the FiiO D-3 as well.

Recently purchased Heresy IIIs and a Coincident Dynamo 34SE mkii 8 Watt SEP amp.  Being driven by a Mytek Brooklyn DAC/preamp. Formerly had Audio Research gear and Focal Electra 1007BE standmounts. Totally gobsmacked about the resolution and dynamic range of these speakers. They have a reputation of being a party speaker, but to me they sound great listening to all genres at low volumes in my 12x14 foot den.  They can be placed close to the rear wall, have a cool retro look and are unobtrusive in the room as Wolf points out. His posts and system had a lot of influence on my decision. 
Have you considered buying used? Not sure how much improvements were made with the IIIs, but would think you could pick up some IIs for less than $1000/pr.

Where the volume control is pointing has NOTHING AT ALL to do with power. It is relative to gain. Turn it up.
Ok Ill turn the volume up more. Was  afraid of damaging amp and/or speakers. Hardening may just be room reflections in lively space.

Decvans,
Thanks for your listening experience w Heresy III. I'm excited about the prospect of owning them, but it may be a slow train coming. I've read IIIs are smoother and better than earlier version with mods.
Tekton Design in Utah. They just introduced a new speaker named "The Perfect SET". I am ordering a set today.....
