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,

To all Teton lovers responding. Tectonic 'the perfect set' looks interesting, though unusual looking and a bit lower in efficiency.
Btw Al, Mystere doesn’t have regular rotary pot volume but resister ladder control, if that matters.

Photos of the amp appear to show that the minimum position of the control is around 6:30 or 7 o’clock or so, and the max position is around 5 or 5:30 o’clock or so. And of course the control is rotated between those positions, as opposed, for example, to a control that is rotatable through multiple turns (with a separate indication of the volume setting being provided), or a control that consists of an up button and a down button. Given that, whether the control is a continuous pot or a stepped resistor ladder makes no difference with respect to what I said earlier.

Good luck. Regards,

Dcevans,
If you want to be amused, Israel Blume went on an amp buying spree some years ago before he started making amps.  This is  how I got introduced to Coincident.  He traded me a pair of Conquests for my fully restored pair of Dynaco MKIVs.  I would be curious if the Dynaco design carried over at all.
I went from 200 wpc Aragon amp with Large Infinity Rennaisance 90 floor standers, to Quicksilver 40  watt tube monoblock amps with Proac 1sc stand mounters, and small 10" powered servosubwoofers, and I am enjoying the hell out of them.
