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

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?

From what you are saying, by swapping in another preamp, the phono input overload and the preamp itself are fine. And the overload zapped the input stage of your Adcom(?) monoblocs?

Sorry you had this happen.

 

I’m trying to understand what you did wrong? The Mani is a phono stage, and you connected it to the phono input of your preamp?
