Louder Hum from amp and Thump, thump sound spkrs


Hello.

I have a Pass X-350.5 and Wadia 861. Not using a preamp.

Last week had the system on but not playing at the time. There was a brief electric outage and then the CD player was playing.

So I powered down and everything seemed alright.

When powered up my Pass amp was humming a little louder than normal. I played a CD and was OK.

Now when shut off Pass X-350.5 amp there is delayed loud thump sound coming out of each speaker. First a thum sound from the left speaker and then a split second from the right speaker.

Did that little electrical outage damage my amp or CD player?

Why now I am getting a louder than usual HUM coming from amp?

Also, the double thump sound? I tried different cables, new fuses and still results remain the same.

How can I resolve? Any future precautions?
Thank you very much.

It turned out to be a defective michael wolff cable that was causing the hum. Very shotty termination and very disappointing on the quality of the cable. I bought this cable on ebay and paid only $38 with shipping. After seeing what the cable is made of internally , I overpaid.
