To recap, the darTZeel amp needs continuous burn-in for three to four weeks, as mentioned in the 6moon review.
As a result, the importer could not burn-in the amp for Mr. Firtz. Only Mr. Firtz could burn-in the amp for his review.
I would like to declare I was against the darTZeel amp and think it is simply a "soft, smooth, dynamically compressed, tube-sounding" overpriced solid state amplifier several months ago.
Now I change my mind, YMMV.
