A friend of mine has given me a LP12 on 'long term' loan. It has an ADC ZLM cartridge and a very old cable to connect it to my Arcam A28 amp. The issue that I have is that it lacks a little top and bottom end compared with my DAC Magic and I wondered if this might be due to the 30 year old 2m long cable that’s being used, that looks like it has seen better days. When I first got my DAC I tried various cables and found that a shorter silver coated cable gave better bass and treble and wondered if this might be why the LP12 sounds like it’s lacking somewhat. Help would be appreciated as I know that it could sound amazing if I get it set-up right. Thanks.
