Interconnect Length


If I were to connect a turntable to my integrated, what would be the maximum interconnect length I could use?
Would 20ft be ok?

THanks for helping - I don't even know what cartdrige I would use - I have not touched nor consider getting a turntable since I am 14 years old... I am out of the loop. 
All I know is that I would use RCAs into my integrated, and I would place the turntable on a dedicated stand, to avoid all vibrations from walking and playing the sub on hardwood floor.
Maybe I could place it on the left corner of my room... (see my room in virtual systems).
Is it possible to mount your TV on the wall? That way, turntable would fit on the component stand.
Don't put your turntable in a corner -- this is a bass node and will maximize interference with your table. Ideally as others have noted the cable to the phono stage should be as short as possible.

One option to consider is getting a small phono stage that you locate next to the table connected by a 1M cable - then run a longer cable from the phono stage to your amp. Of course your amp has a MM phono stage built in so you could go with a head amp and a low output moving coil and the run the longer cable to the Marantz. Even a step up can help -- I currently run 2M cables to my step up then another 2M to my phono stage and have no issues
@goheelz  yes ! - that's what I was thinking.  I don't know how to elevate the tv; I Know I do not want to mount on the wall.  
Maybe I can place it under a stack of hockey pucks right under the "feet"... All I need is 5inch of clearance.. I just have to look for a base, maybe build one.  The TV is 6 years old, so it is heavy by today's standards.
