Need an advice about phono cable. RCA-RCA

I agree with TWL. There is no way a properly set up and functioning analog setup like yours can be beat by that CD player, even with lousy cables.

These arms are a bit unusual to set up but are capable of excellent sound. I hate to ask a stupid question but since I am unfamiliar with Linn models, does it have a phono stage?

Take a close look at the azimuth. You have a micro ridge type stylus on the Glider and will be quite sensitive to this adjustment. NOTE: ther is a "delay" effect when setting this due to the "goop". You can't set it and then walk away. You need to wait until it settels in and then slowly tweek it. You will need to make adjustment in small incraments and anticipate for the change until it is in the groove straight up and down. If this seems confusing just ask and I will try to explain this phenomenon further.

I'm certainly no where near as knowledageable as the others here, so I'll only chime in to add that when I received my new mmf-7, the cable was defective. I replaced it with a different cable and everything worked fine. Just a suggestion to try a different cable.

Good Luck! Mike.
