Hooked up Shiit Mani incorrectly

I feel really stupid right now. I hooked up my Shiit Mani to my phono input on my Adcom GFA 555 preamp causing both my speakers to start distorting. Once I realized my mistake I shut the system down. I believe I may have damaged both my amps in the process.  Both amps are humming when turned on. What damage could of done? Any guidance would be greatly appreciated

I swapped preamps and the problem is still there. I will swap both amps out to see if any other damage has occurred. Hopefully the speakers are ok

Continued to troubleshoot the amps by disconnecting the inputs to the amp leaving the speakers connected then powering up the system the hum is no longer audible. Does this mean the amps are ok?

Contacted Shiit tech department to see what they say. I'll post their response

According to Schiit no damage should of occured to the amplifiers possibly the speakers could sustain damage if the volume is set high which it wasn't around the 8 O'clock position . Also, he wrote that damage to the preamp was unlikely and should contact the preamp manufactures for more info. Not happening since they are no longer in business. With that being said I will hook everything back up and power up the system to see what happens. Hopefully I will be spared any damage.
