VPI Scout 2 vs. Luxman PD 441

" Maybe a Scout 2 with JMW 9 arm?"

That's what I have. I wouldn't hesitate to buy it again. I've never compared it to your current TT, so I really can't say anything definite on that. That said, my guess is that it would be a very nice improvement from what you now have. Also, VPI usually offers a nice selection of upgrades so you're not forced to get a new TT if you want to improve things in the future.

" For those of you suggesting I keep the Luxman, do I need to spend in the $1,000 range for a better tonearm than the Denon?  A past suggestion has been a Fidelity Research 64S."

Unless you have both TT's for a comparison, its extremely difficult to judge one over the other. I would recommend that you work with a good dealer. Try Larry at Hollywood Sound in Hollywood FL. All he does is turntables. He sells VPI and he probably has some experience with your current TT. He'll give you a straight answer and won't try to sell you something that you don't need.

" No reflection on Hollywood Sound, but the chance is close to nill that a brick and mortar store will understand or communicate the merit of a vintage table or tonearm relative to current production."

That's just a stupid thing to say. Larrys considered to be one of the best TT guys in the country. You're judging someone you don't know based on a guess. How on earth would having a store inhibit him from being able to properly explain the pro's and con's of vintage TT's? You have to have someplace to work out of. 

If you've ever been to his store, you'll see that he has rooms filled with vintage TT's. He has the biggest collection I've ever seen, and probably has the OP's Luxman in the store. If you don't believe me, go there and see for yourself.

I'm extremely picky about the people I recommend. If I'm not 100% sure on someone, I won't mention them.
