First impressions after somedays of listening At33Sa. The sonic characteristics of PTG are maintained but SA increases the efficiency of the low frequencies that are more controlled, less slow and more articulate than the PTG (I'm very fascinated about this). I am surprised by improvement in the mid-high frequencies that in PTG are 'magical'. On At33Sa there is more definition !!
A great quality that I'm noticing is that at33sa is very quiet and this allows better microcontrast and microdetails.
Up to 1000 Euro and really hard to do better !!
