What's your cartridge's voltage, is it MC or MM? The crackling noise is usually from the tubes especially if they're running through a very high gain stage like 52 dB. Depending on the tube type you may be able to try a lower gain/noise version, e.g., 12AU7 vs. 12AX7, etc.
Phono preamp make crackling noise
Looking for advise from any of the audio Gurus.
My set up consist of Unison research Unico pre connected to Auris audio Forte 150 mono blocks, my speaker are Focal Sopra N3. I also have BLUESOUND NODE 2 (Dac/ streamer).
I do not have any issue with noise when I play music through my BLUSESOUND NODE either Tidal or Spotify..
I recently purchased Unison Research Simply phono Tube Phono amp with separate power unit. As soon as I connect the ’Simply phono’ to pre amp and set to appropriate input I get crazy cracking noise on my speakers. It is not a ’Hum’ like you hear with ground issue. I don’t even need to switch on the Turntable. It overpowers the sound of my music.
I am trying to eliminate each piece of my equipment. I even took my Phono preamp and the preamp to a Hifi audio store . we connected my equipment at the store and amazingly it played without any noise. I have changed interconnects / power cables still it is noisy . Looks like the issue is in the wall electrical. I just moved to a new house.
Any help will be appreciated. I even tried to move my NAS drive away. Just driving me nuts!!!!
