Hello, great op amp, perfect sound control. Unlike the Bursons, which are very good, here we have an added analog part, that is, more ideal for those looking for softness. The edges are soft, not strident, the treble is refined and the mids are well articulated, not exaggerated but harmonious. The very natural bass seems as if it hits a very natural real bass drum. Honestly, it surprised me, on the other hand the separation of instruments is not bad and the separation by layers, that is, the enveloping effect, is very good. Recommended.
