I've bought a Denon DP-300F turntable from richersounds but I'm having problems with albums occasionally jumping. None of my Lps have jumped before on my old turntable. I've set the antiskating and counterweight to 3 now, which is slightly above the recommended 2.5. Richersounds said it would be ok to do this and to bring it back if there's no improvement. Some albums still jump but not all of them, so I will take it back. Has anyone encountered this problem with Denon turntables before. Is Denon a good make of turntable. I know cheaper turntables have always caused LPs to jump. This one cost about £200. What do you suggest? The shop emailed back and said they could get an engineer to check it out. Is this turntable a good enough one to stick with, or should I ask to upgrade and spend a bit more. Thanks.
