Through the link I provided above, I came about a recommendation for the AT-VM540ML.
I really didn't expect it to be so noticeably better. I even went in expecting no change. When I got it, I found some things very unsatisfying and I thought, with such poor attention to detail, how can it be truly better. I expected it to be the same as the one I have.
But it was much, much better. It's impossible for me to do direct comparison as I have one TT and the weight of the cart rigs is different, so every time you swap, you have to go from zero-balance onward setting the tone arm, so it couldn't be done. At least I couldn't do it.
I had to go through several records I find problematic in some way and see if i notice any change.
Anyway, it is what it is. I had no expectations, but it simply convinced me. It turned me around. I found my set up. I'm not changing until it breaks and even then I'll try to find the same one. I'm very happy with it.
the difference i heard (or thought I did):
I have a record with annoying sibilant sound - it was much milder.
I have a record that is messy and noisy, like it was played in a well - far, far better resolved and separated, I played it real loud and could still talk to people around me
I have a bass heavy pop record that was always flat and lifeless - tight and punchy now with a lot of low end
