Tube amps

I don't think one VK 60 would have enough power to drive the WP's. But, with a pair of VK 60's I think you would be pleasantly suprised. If you had those amps converted to monoblocks they have zero negative feedback, and the output transformers and power supplies to handle the low impedence loads that would be thrown at them. I think this option is very economical at less than 1/2 the cost of a VAC or CAT. Don't get me wrong the VAC and CAT are exceptional but the BAT can deliver the current and power as well.

Jensmunk, After reading your post again I need to clarify my response. One VK 60 might drive the WP's. With the information you provided it's a difficult question to answer without more information. How big is your room, do you listen to lifelike volume, what type of music do you listen to, and are to willing to sacrifice chest thumping bass? With this type of information you might be able to stay within your budget. BAT has paired up with Wilson at numerous audio shows and is very familiar with the product. You might give the folks at BAT a call as well. Good luck in your journey.
