Hi, everyone. I want to upgrade my system, which includes Debut Carbon DC OM10 , Denon PMA-520AE and QA3030i. However, since my budget is tight for a large-scale upgrade, I am thinking of replacing the Ortofon Om10 cartridge with the AT VM95SH. If I also buy an external phono preamp, will I see a difference compared to the internal phono preamp in the Denon? I have two external preamps in mind. Rega Fono MM MK5 and the Cambridge Audio Alva Solo as an external preamp. Which one can I get better performance from with the VM95SH?
