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

The damage is in the input stage of your amp. You’ve just fried it.

Overloading input circuits causing the most sophisticated damages to troubleshoot pretty much.

If you are lucky, all you fried is your phono stage.  Have you switched away from "phono", hooked up to a normal input, and still have problems?

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

I fried like that my Nak tape deck by accidentally connecting to the phono output.

I've identified quite a number of components that had been clubbed by overloading  and it was quite a number of miniature caps, transistors and diodes.

Ouch!  Don't be too hard on yourself.  We have all been there.  

Not wanting to hijack your thread, but do you think home insurance would cover the damages?
