Maxmad:It depends on the balance you are seeking.I have great respect for Mullard and Brimar.Bur neither is capable of especially extended highs.They do add warmth to the mids,but not the extension or articulation to the extremes.I have owned both.That being said,the cabling/room and speakers will contribute to the perceivied sound.
When my friends and I were listening to output tubes in the PL,we were strictly sampling current kt-88s.The PL2 has the ability to extract the benefits of this tube type.IMHO,the 88s are the most musical/reliable of the current production tubes.I believe this subject has even been touched on by HP and TAS.
At the time of our evaluations,the Anniversary Shuguang had not been introduced.You therefore may discuss the difference between the Anniversary and the 88/98 in the upper-end,with you preferred Shuguang vendor.
If I were to be looking at the el-34,Siemens would be my choice.
