The Bellari is not going to be an upgrade. Sideways move at best.
You don't mention your cartridge, but if it is the stock Ortofon that came with these tables, an upgrade there would be money well spent.
Either that, or up your budget.
Suggestions for a Phono Preamp.
I currently have an Audio Technica PEQ3 Phono Preamp in my setup. I am using a Pro-Ject Debut III as my turntable. I am going to keep my preamp and get a newer one for around $200 to $300 dollars. I am thinking about a Bellari VP130 or staying with Pro-Ject and getting their Phono Preamp. Any suggestions? Thank You.
