I still think “Proper hi-fi” is a fiction when it comes to vinyl but there is definitely a sweet spot where the hardware doesn’t add more noise to the signal.Yeah I get you. I have a pre-amp worth about 400 quid (Pro-Ject Tube Box DS) and a pre-amp worth about 15 quid and the only noticeable difference is you can easily earth the expensive one and remove a specific non-earthed buzz. In your case i'd say don't get that one above, spend a little more than that, but no more than 150-200.
I imagine if you're into proper hi-fi worth thousands and you're talking genuine tube pre-amps it's a whole different ball game but it's unlikely i'll ever be rich enough to find out.
