At 160/8Ohm & 230/4Ohm (as measured by stereophile) Dart is not the most powerful amp out there, but as long as you don't ask it to drive sub 2.5 Ohm loads and within its power rating, Dart can be a true magic.

It is certainly not another 'me too' product, and Herve Delatrez, like Nelson Pass and Charlie Chansen, is one of true innovators in this industry.

You forgot to mention, that the dart dislodged the $60k 911mk3 monos from your system :)

I sold my dart since it was not able to drive the punishing load of Sasha, but since I sold my Sashas, I considering getting another one. Yesterday I have heard the dart combo diving the Maxx 3 (with $200k worth of Siltech cabling and Metronome C-8 DAC) and I was literally blown away. I do not think I have ever heard a more natural sounding system.

As a rule of thumb, I would say that to get the magic, you have to avoid speakers that dip below 2 Ohm.
