Hey I I have a chance to pick up a pair of ealry edition Wharfedale w90s for about $400 this weekend and I have to make a decision fast. I'm currently running Altec 890c Bolero horn speakers with a scott LK 72 tube amp (35wpc)...is this a worthy upgrade in anyone's opinion? I know that the Wharfedale w90s earlier models are more efficient and are recommended with tubes. The real question however is will 35wpc tubes control these speakers and play well at louder levels? I have liked what I heard in the wharefdale w70e's I previously owned but I like my altec setup currently. Does anyone have advice on whether it's worth it to fork over the cash for these big Wharfedale's? The seller is claiming these are in all around mint condition with fully operating tweeters and drivers.
