Charles,
There are two types of PSvane 101D. The 1:1 WE replica has only just been released in China and is currently not available elsewhere as far as I know. The other type which some people also like has been around for a little while, but is nowhere near the same league as these new ones.
All 101D 's to date are based on WE designs but these new ones are 1:1 exact replicas all the way through, like others in the Psvane WE replica range - ( their very best tubes)
Brownsfan, can you confirm which PSVane 101D's you have been using?
I cannot emphasise enough the difference between these exact 1:1 WE replicas and the regular PSVane 101D tubes from their HIFI range. The audible differences are huge ( I own them all) . I paid around $600 for them but don't know what they will retail for when generally available. Given that genuine WE 101D's in reasonable condition will set you back $000's and are often of dubious quality, these are a bargain I think
