I've owned the Psvane TII KT88 and 6CA7 tubes but only listened to the KT88s in the CAD 120S MkII. They sounded more dynamic but the midrange is not as sweet and pronounced as the Svetlana/SED Winged C EL34s which are biased at only 100mA with the pot maxed out. Cary Audio stated in the manual that it supports EL34 with 140mA bias but owners could not get that high.
Anyway the Psvane TII tubes are more expensive than the Shuguang black treasure and supposed to sound better. I also owned and listened to the new Tungsol KT120s in the same CAD 120S and they have bigger sound overall. I've also owned and listened to the Svetlana Winged C 6550s and they sound not much better than the KT88s. I've got the EH GP in the driver and TJ Full Music gold pin in the front end. The CAD 120S MkII is driven by the SLP-98P with Telefunken in the phono stage and two Sylvania JAN WGTA in the front end and the TJ Full Music gold pin as driver. I've not tried the acquired JAN CHS V231 Sylvania GTBs yet but for only a few listening hours with the more expensive MELZ 6SN7 in the CAD 120S, these cool looking ones sounded really wonderful.
The CAD 120S MkII is only a few months old with the Clarity factory upgrade but the Vcap CuTF have replaced them. The SLP-98P had the Mundorf S-G-O cap upgrade with better resistors. I also installed bypass capacitors in both.
Both are driving the new Maggies 3.7i speakers with AQ speaker cable and Columbia interconnects.
The REL sub is fast enough to keep up with the very fast ribbon drivers.
The result is breathtaking! The musical instrument clarity is just outstanding. So are the soundstage and image with better accuracy. For example the saxophone notes sounded so lively vibrant that they slightly annoyed my ears (you know that happened when getting near to a real saxophone playing).
