OP,
Yes, the impact of a great phono stage is incredible. I remember purchasing a $200 “A Recommended Component” Phonostage from Stereophile nearly 40 years ago. It sounded just terrible, I mean really bad. That started my upgrading that only slowed when I bought an Audio Research PH2… but upgraded as fast as I could afford it. The impact only slowed when I bought an $8K (I think) Audio Research PH8… but I continued upgrading and getting benefited to my current ARC REF 3. Really important!
