Willip ching , in my humber opinion, no one tube including very expensive NOS tube is an universal winner. Every one's choice of tubes might be based on the sound what you like. From my choices of tubes in the tube phono amp, you cannot find some kinds of sweet, warm and colorful tubes such as Mullard, I adopted Valvo and Amperer tubes in the amp for clear, dynamic amd linear in whole frequency, but I added tfk ECC88 at last stage for airy, musical and vivid high and mid-range frequency. Hence, every one treasures his owned favour and no one universal favourite tubes in my mind. My favourite sound from the amp is coming from my mixed use of the tubes according to the original circuit design of the amp. |
