I owned the Decware Torii IV, then quickly upgraded to the ZMA. My speakers needed power, thus the ZMA was ultimately the better choice.
I did like the Decware gear better than Primaluna, but I have since changed over to Linear Tube Audio electronics which mate better with my speakers. LTA also has many Tekton customers. Their 10 watt (conservative) amp would more than drive Tekton speakers.
Decware amps are the best sounding transformer driven tube amps in their price range, and Decware is a super company to work with. If I hadn't discovered LTA I would still be blissfully ignorant. I also really liked Decware's looks, but that's shallow and doesn't help the sound.
The LTA gear eliminates traditional iron core output transformers, which provides better transparency, better dynamics, great bass, and 3D imaging. The tube sound has no transformer haze, that you don't realize exists until its not there. The ZOTL10 will have the same driving power of the Torii (forget the stated wattages) and costs $300 less.
I use the ZOTL40 rated at 40 watts/ch, the same stated power as the Decware ZMA. The difference in driving power is not subtle. Oh, and since LTA gear uses David Berning's ZOTL design, tubes last from 10-20 years and are auto-biased. Without the transformers, the amps are also featherweight. I had a 100 pound McIntosh amp once; never again.
