What's next after my 300B Rega Turntable


I a very happy new vinyl lover. But I've got the itch for a significant improvement in my turntable. One of my dealers is recommending the Well-Tempered Classic, but does not have one to try in my home. Thoughts, ideas, recomendations for a turntable under 5K. Thanks

Teres Model 255 Signature in Cocobolo. Origin Live Encounter tonearm, Shelter 501 MkII cartridge. That gives you the whole package for just under $5k. I speculate that you would have a very difficult time beating that for $10k, or even more.
Origin Live Resolution table. Origin Live Encounter tonearm. Shelter 501 MkII cartridge. Total is just under $4700. Origin Live gives a 14 day money back guarantee (I think you pay for shipping, though). They have U.S. dealers listed on their website.
Wait a minute. We have a question here about which of the "Poobahs" is higher. Is it the Great Poobah, or the Grand Poobah? Is anyone "pulling rank" here? Is there some kind of accepted "Poobah" hierarchy?
Didn't mention the cart you have. Why do you want to dump the rega so fast?
Since you say you're "new" to vinyl (welcome!)I'd keep the rega w/ unknown cart, and put $3k into used and new vinyl, save the rest, and wait till next year.

Do not ever talk to dealers about recomendations. They will always have one. It will not be what you have, nor will it be for free.
Shasta, not all dealers are cads. Some are very much interested, in giving the customer great sound. Though some are not, but a blanket comment such as that, is not fair, to those who truly care.
