2018年10月19日 · I've tried 6U8A RCA, but ECF82 Polam goes much better. Those Polish Tube Valves sounds better in overall, but there is a annoying problem with vocal sibilance (especially "S" syllable). Is there any good sounding ECF82, 6U8A, or 6F2 known by anyone? Preferably with good dynamics, good bass control, smooth mids and without overbright hi-end?
