I have had a LOT of turntables over the years, last count was 50 plus, of all drive types, suspended, non suspended, lightweight, flyweight, every permutation you could think of.
And made probably at least 20 something.

And what i have learned is that until you sit in front of them, you might as well write them all down, put the paper on a dart board and chuck a dart at them to make a choice.
There isnt a substitute for standing infront of it with some ears and music.

I have one deck that has stayed for a long time, nearly 15 years, out of all of them. my jbe slate dd. Because i like it and it just plays and i always come back to it. The only other one is one that i have had 3 of, the jvc ql-y5f. Because they sound bloody good, and my wife uses it because its full auto and she wont use a manual deck.

Ask yourself why you want to throw money at a new one, and what you are actually looking for in doing so.

In reality it is a hard thing to do to arrange to listen to these things, but it is worth it. Changing an arm or a cart wont fundamentally alter the character if a deck in my experience, and throwing money at the 'problem' wont either. Identify the 'problem' first. Listen to the systemdek, have a good think about what it is about it that you actually want to change before you put hand in pocket
