Get away with 35-40mm clearance above a Marantz PM6003?

Hi,

I've got a PM6003 in a custom-made unit and want to add a Marantz tuner but as they are so big it will eat up the room at the top. It will sit on a CD6004 with just over an inch to the sides, no front on the unit, just enough at the back for the interconnects. Above, with a tuner in there as well, the front half of the amp would covered at a height of 35mm with the rear half going up more like 110mm (but also enclosed).

I know the official guidance is for 4-5 inches above an amp, but the PM6003 is not very powerful (45W per channel I think), and I probably won't use it at high volume very often. Will i get away with such tight clearances or will it power itself down the whole time? I can engineer some more space but it would be a lot of work.

Couple of other questions: I also didn't leave room for a plug to fit down the back of a shelf between the kit and the power socket (yes, I know, I really thought it through...) - is there any reason why I can't cut off the plugs and fit new ones in situ? Will it damage sound at all?

Finally, sorting out the cable mess - what's the minimum distance I should allow between data cables (speaker, interconnect, HDMI, aerial) and mains power cables? Can data cables be bunched together with impunity?

Thanks,

Chris

4 to 5 inches clearance? Are they kidding? I don't have thsat much above my valve amp. You should be just fine with what you have as the PM6003 is never going to run hot enough to worry about.

I would check the guidelines in the Marantz manual for clearance, but you should be fine.

Keep signal cables a few inches from power cables, if they have to cross paths it should ideally be at 90 degree angles.

Fitting new mains plugs will make no difference what so ever.
