I have heard the Dartzeel monoblocks at a show for a prolonged audition, with magico Q5 speakers and yes they sounded phenomenal. I am not sure with my priorities, I would need anything more than the integrated.
Having heard a Nagra and Dartzeel based system and would happily settle for either indefinitely, but yes prices are insane, even second hand. The penalties I suppose, of the Swiss Franc becoming a reserve currency.
I bought my 9ct gold omega watch when I was 17. Used every day since, soaked 3 times, once in a washing machine! It still keeps pretty good time and I'm 63. Is this a record, I suspect not?
