Hello; \n\nI purchased a tx-nr636 onkyo receiver to be paired with a turntable. For digital sources, the Onkyo is amazing. However, the phono input, paired with a Carbon using a 2M red cartridge sounds absolutely horrible. Is this thing broken, or is this how they wanted it to sound? \n\nIt basically sounds like AM radio on my polk audio tsi500s. It is loud, but lacks detail; painful to listen. \nI have noticed the high hats, cymbals etc. are greatly reduced compared to any digital source. Using good headphones, Sennheiser 598s, the bass is overly present and sounds muddy. I was very surprised by this, since both the receiver and turntable have universally great reviews. \n\nAny suggestions? \n\nThanks!
