The price of JPNs and VTGs is going through the roof as more people decide they like them. Considering rarity and age, it's not surprising they are going up. As to the W2002s being better with the HA2002, sure, if you buy the 1 amp they don't sound like ass with, they may sound better. Who wants to buy a specific amp for them. The JPNs and VTGs may not be "best" at anything, but they sure sound good, and if what you want is euphony and not resolution and detail, they're a great choice.
