P10 Placement with Phono Stage

Hi all, silly question. Perhaps it has already been answered. Is it unwise to have a Phono Stage on an AV rack directly above the P10? There is about 4 inches between the units. Should the Phono stage be further away (a higher shelf)? Thank you in advance for the input!

Unless you hear any audible hum / distortion it should be fine. You might find that the signal and power cable positions need careful placement.
If you do hear hum you may need to move the components further apart or it might just be re-positioning of cables. Good luck.
