I use Joe's Tube Lore as a touchstone; it is outstanding work by Joe and I agree with most of his listening experience. As always, room, rig, taste will determine what one settles on...the RCA Clear Tops in my Primaluna were very good, just not as good as Amperex in this case, but still a quality tube, better to my ears than Primaluna stock tubes. A good bargain NOS tube is Telefunken clone, labeled Ei, built in/on the same Telefunken machinery by Ei; also NOS not made any longer. I have those as well. NOS and used, but test as NOS. Best, Rob

Please help me. Looking for new tubes. I read that it is difficult to beat the stock tubes, but I am willing to try. I am currently running a Pass XA-30.8 amplifier, Harbeth Super HL5+ speakers and an Esoteric K-07 as a source. I listen to rock, jazz, classical. Love female vocalists accompanied by the piano as well. I want to avoid anything that will accentuate high frequencies or anything that may cause harshness in the upper registers. All that being said, I was considering Amperex Medical 12AU7, Brimar CV4003, Cifte 12AU7 or Mullard cv4003. Or something else? Thank you in advance.
