Is it worth upgrading a Thorens TD125


I Have a Thorens TD 125 TT with an SME 3009 tonearm.
I would like to upgrade it.It is in very good condition.
I would like an excellent midrange, very good base and very good treble.

How do I start?
I am not mechanically minded, so I will have to get someone to do the modifications for me.

Where do I start?
And what will I need?

Tks in advance for your assistance

To the best of my knowledge all SME arms take the same cut out, as do several other arms. I was an SME dealer in past years and in my experience all standard length SMEs will fit.
