VPI Scout 2 vs. Luxman PD 441

I agree. I sold my Luxman PD 444 because I didn't think I needed two arms. I have regretted it since. I would replace the Denon arm. So, to answer your last question, I believe that you could sell the PD 441 to recoup some of the cost of an upgrade. I, for one, would have an interest.

" 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.

Consider a Micro Seiki MS-505(the original version, not a MkII or MkIII) They are $800-$1K on ebay, depending on condition and completeness with accessories and box.  It's a great all round arm and more versatile with modern cartridges than a FR 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.
