Removal of plug/wall outlet - hard connection ?

Yah ! I Have to agree about trying to ever file an insurance claim..Doesn't matter what happens ,its an escape route for the Insurance company..It your dice.Rollem if you wish.........

I don't think it is wise. My Njoe Tjoeb 4000 CDP had a cheap little 2 wire cord. I replaced it with a better cable (and will upgrade it again soon) which is hard wired to the power block inside the unit, and then goes to a nice plug and nice outlet. I unplug my electronics during electrical storms and when I am out of town. I worry less. You will not have this option.

Terryakhan, I've done something similar about 6 or 7 years ago where I had excess slack in my dedicated lines and I connected an aftermarket IEC connector on the end of the Romex in order to plug the Romex straight into the back of the amp.

Before and after this tweak I was using excellent power conditioning and so even though the tweak might normally provide greater benefit, in this case it was a downgrade in performance simply because there is no substitution for proper line conditioning.

And though there may well have been some recognizable gains had I not been using excellent line conditioning I would have to imagine there are other areas of AC modifications that will bring far greater benefits including proper line conditioning, aftermarket plugs and IEC connectors, and cryo-treating plugs, Romex, cables, IEC connectors, ics, and scs, etc., and still remain within code so as not to void potential insurance claims. Double-cryo-treating is even better.

-IMO

amps are not designed to be hardwired, no more than a veg-o-matic.

Thank you for your kind responses. I found the answer out for myself this weekend.
Sonics have more than improved, low level information is louder and clearer, bass notes have gained another octave, normal level setting on my preamp is about 75 now I have turned it down to 65. This improvement is greater than that the ones generated at my speakers plug ins removal.
The PCs are hardwired at the plug in end only, directly to the Romex feeding the outlet box in the wall, inother words both the Oyaide male AC plug 079 and Oyaide SWO-GXX wall outlet been removed, on all four of my amps.
The amps are still feed via the PCs but without being plugged in, but hardwired instead.
The 4 amps are still plugged in with the IEC at the end of the PCs. This type of connection can be also eliminated by the removal of both the IEC plug and socket, but this means entering the amp.
I have conducted this test only because of what I discovered after removing my speakers WBT plug and sockets.
And I am convinced that plug in devices do create some losses I have never thought could make so much differences.

Thx Terry
