How good does a TT have to be for a good cartridge

A better table will improve the sound of a modest cartridge more than a poor turntable will be upgraded by an expensive cartridge.

As long as the arm is compatible with the arm and you have a good phono stage you will get better quality sound from a better cartridge on your tables. Though there are better turntables out there your tables are still very good and should work well with better cartridges

Although I may be lacking in experience, compared to many on this site, I used for several years a Dynavector XX2MKII on a Scout Signature, with a couple of phono stages, Simaudio Moon LP 5.3 w/outboard power supply, then a Modwright SWP 9.0 SE. What happened is the Scout just sounded much better than the Lyra Dorian it replaced.

I'm off in a different direction now, I'm in the finishing stages of a Garrard 401 restoration/upgrade, mounting a Dynavector 501 arm, and I'll use the XX2MKII here as well. I'll see if this project sounds better, or just different, but who knows?

I'd sure like to try the Dyna XV-1S, or an Ortofon A 90, but those are not in my comfort zone money-wise.

The lipstick adorned pig enters in here, too, but I couldn't tell you where that is.

Good luck, and good listening,
Dan

I have had the Scout [I am a VPI dealer]. While it is a good table I would think a cartridge like the Denon 304 or AT 33EV, both of which I used with it, would exhaust its potential. There are two schools here; mine is that the table is the critical element , very closely follower by the arm. The cartridge is important but it is better to go for the very good TT/arm first; it will get the most from whatever cartridge you choose. Conversely, the lesser table will not realize the full potential of the expensive cartridge. Sell the Scout, put the money from it with most of the 3 to5 k$ and spend something like a $ 1000 on a cartridge. THEN upgrade when and if you have the urge. Otherwise you are wearing out the expensive cartridge without realizing its potential. I am sure others will argue the opposite position.

It makes more sense to put 5k into a better tt and arm and use your existing cart. Then when the upgrade bug strikes again you can justify a better cart. Though it depends on if your phono stage is up to the task. You may want to upgrade your phono stage as well before you move up to a upper end cart.

In general the higher performance the cart the higher demands it puts on the other equipment in the chain. IMO
