Just thought i would let you know that i have installed a pair of new WE Replica 101D tubes onto the CSLS. They are made by PSvane and are available in China only at the moment. I bought a pair while at the Guangzhou hifi show . They are available with current 300B type pins as well as original WE pin configuration. Link below.
How do they sound? in a word WOW! Highs and lows are more extended, larger soundstage, more detail, better midrange, better dynamics and bass . Did I mention they look sensational too? Check this out:
