DISTINCTION from RT001 12AX7A-C and RT003 ECC83-CZ Premium Selected: Compared to the RT003 and RT001, the RT093 shows a little more edge in the high-mid range. As a result, it asserts itself tonally very well, which makes perfect sense in a band structure. RT003 has a more central tone and thus brings more warmth and a little less brilliance and depth definition than the RT001 and RT093. Due to their tonal structure the RT093 and RT003 are somewhat less sensitive than the RT001 when used in extremely microphonic sensible applications.
