If the amps are humming by them selves with no other components hooked up than you may have a incoming power problem. You may have some DC on the incomming lines. You mention amps so I'm asumming there are two and it seems odd that both would have a problem at the same time. Most power conditioners will be of no help in solving this problem but as mentioned above the PS Audio web site explains in great detail about hum and why! They do have a product for this problem called the humbuster. Good Luck!

Ortofon Rohmann select cartridge
Ortofon N8 copper interlink (blue)

MIT 350 proline reference interlink
Mark Levinson 380S line preamp
Nordost Valhalla balance interlink 30 ft
Mark Levinson 33H power amps

Power amps are humming (not over speakers but in power amps themselves;
Sound far too airy, hardly any bass. For CD reproduction sound is 'okay' for now.
