I just bought one....finally pulled the trigger. After discussing with myself...if the money is justyfied.
Bought the A30 pro for 249€.
I have/had a SMSL SP200 for something like two years now. This is a fantastic and strong Amp. But together with my DT1990 pro it may be an "unlucky" combination.
I´m listening the first hours with A30 pro now....but already have the opinion it was right to somehow "side-grade" to the A30 pro.
DT1990 pro was pretty "challenging" on longer listening runs with the SP200 since its very strong on the highs and SP200 seemes to support this matter.
I have the Filter from "Solderguy" installed and still its...."challenging"
And I´m from 1976.
With A30 pro its more laid back, less stressing. But still the same authority...the same punch.
Details seem to be a very little on the plus with the SP200, but this can be because its sounds brighter....false recognition on my side.....beford final conclusion I´d want to have 20-50 hourse on the Topping. The A30 pro seems to have even blacker background wich blows my mind. SP200 was a new universe to me back then and everyone ever head my combination is shocked how clear music can sound
A30 pro tops SP200 in this regard.
