Mullards are great in bass in the EL34s I run in my highly modified voltage regulated Dyna Stereo 70. Deep and punchy in Legacy Signature IIIs. Also, the Mullard 12AX7 I get great bass in a 3rd system with an EAR 864 preamp using the military version CV4004 which is very open and detailed (not bright just balanced with a wide frequency spectrum), totally unlike original Mullards which tend to be very warm sounding.
