Removal of plug/wall outlet - hard connection ?

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.

Terry, there's no doubt that what you are doing with the electrical can be sonically beneficial.

However, these specific improvements cannot exceed the performance of proper line conditioning and your dedicated lines are not cleansing the dirty AC coming in from the street.

Moreover, it appears you are altering your components and/or speakers to the point where few people would ever purchase them should you ever put them up for sale (assuming you disclose these alterations in the ads).

In other words, I would like to caution you that there are greater gains to be had than those that may permanently alter your components/speakers.

But I also commend your experimental qualities as you are realizing there is much to be gained from altering/improving the AC.

In fact, since you've gone this far, I would suggest removing the power cables altogether and just load the romex to the IEC connectors going into the components. And then if you're really up to it, contact Cryo-Nebraska and ask them to purchase some 12 gauge Romex solid core at their local hardware store and then double-cryo-treat and ship to you for installation. Not to mention obtaining double-cryo-treated IEC connectors.

Carl109, generally when somebody mentions something like bass notes have gained another full octave, some-to-many of us assume that what they are describing is existing and unchanged bass notes already embedded in the medium have become more well-defined during playback and therefore, as in this case, seem to sound deeper, tighter, and perhaps a bit more accurate.

Hence, explanations such as yours or mine here are usually not necessary. In fact, I would think it extremely unusual for a reader to interpret that statement the way you apparently did.
