I have used the following opamp until today. – OPA2134, OPA627, THS4032. The best is the THS4032, the OPA627 has an identical sound but with less stage. After many hours with the SS V6 Vivid there are some changes in the sound, wider stage sometimes exaggerated, more detailed, more transparent, mainly in the upper and upper middle range, in the lower and lower middle range the sound is defined but does not have the impact of OPA627 and THS4032 precisely where I wanted to improve.
Specs from manufacturer data unless a source below says otherwise. “calc.” values are worked out from those figures (V = √(P × R); 110 dB SPL used as a loud reference level). Gear listed without specs is not in our spec library yet.
