“Hi Rachel. Received the Psvane 12AX7′s yesterday. My intent is to use them as the first stage in the phono section of my Rogue 99 Super Magnum pre amp and based on what I’ve heard so far they are going to perform that function admirably. To break them in and get a feel for their performance/sound quality, I installed them in the V2 and V5 second voltage gain positions of my series IV McIntosh MC275. I have driven them with both a Telefunken ribbed plate 12AX7 and now a REAL Tungsol long Black Plate 12AX7 in V1 the first voltage stage/phase inverter. The Psvanes clearly let me hear the differences in the two tubes. I have had both new production and NOS tubes in these positions. The Psvanes are the equal of the most recent (RCA black plate 5751′s and prior to that Real TungSol Long Gray plate 12AX7′s) and easily outperform all other current production and some late 50′s RCA long gray plate 12AX7′s. And….that’s only with 16 hours on them. “
