I bouthe line magnetic LM219 flagship 845 integrated amp, sound is not clear , treble not extended and muddy, slow and dynamic bad. No idea why people still buy line magnetic products
My LM-845 prem. sounded not clear too before I rolled its preamp Shuguang 12AX7 tubes to Telefunken ones. Pls try that. Also rollimg the stanard Psvane white base 300B tubes to either 2023 Westen Electric or Psvane Acme 300b gave another step clearer. Lastly, the standard brass base Psvane 845 to Psvane Acme 845, same effect but lesser degree. I wish I could buy amps with no tubes option. But some said that Western Electric 310A tubes don't sound clearer than the factory fitted Psvane Replica WE310A.
