Amperex, Telefunkens, Siemens tend to work very well, IMHO. If you wish to stay away from warm, best to avoid the British tubes, Mullard, Brimar, etc.
Right now I am rolling a pair of Pope 12AX7's (fancy Amperex Bugle Boys) in the phono stage, V01 and V02. A Telefunken smooth plate 12AU7 in the V03 line stage with a Mazda Silver plate 12AX7 in the V04 line stage.
Driver tubes V05,6,7 are RCA Cleartops. Power tubes, V08-V11 are Psvane KT88's. Works well for me, as always, YMMV.
Have fun!!
