I generally try to make changes one at a time so that I can assess their effect and decide on their effectiveness.
Speakers wired out of phase would be an easy mistake to make and would reduce bass levels, so checking polarity of your speaker cables might be a good place to start.
Have you considered that the Matrix 2 is just a power strip? If you can you should return it and maybe consider something at the level of the rest of your system…
Seems that the AudioQuest units are popular might want to try a Niagara 3000 and a few of the Storm series power cords
Some year ago I changed the schuko double wallsockets in the livingroom and I’ve only used the one socket for the Naim since.
Yesterday as a test I switched to the unused socket for the first time as a test and it was without bass, the groove was gone.
If I was to prolong the test for a couple of days/a week my guess is it would sound just like the other one. Stick with it for a while and see if it improves.
Chord Music is not yet mine but I still have it,today I have a meeting with the dealer regarding the price,according to the expensive price i will decide to take or to look for a different one…deapending on my dealer mood
I have gone back to the old set up (cheap basic 4 way block) and kept the power line on the new 555 PS DR with the the other powerline I have straight into the second unswitched dedicated Mains socket and to the 250DR
Maybe removing the powerline from 555 and using to connect the WW Matrix causes the problem
Maybe I need to buy a bespoke cable for the matrix and not sacrifice a powerline already in use.
There has been a big upgrade in the whole sound with the recent new 555PS
Maybe you need to break in the Matrix? What I’ve done in the past is to plug the device into the wall and hook up a portable fan and run it for a week. You can even run the fan off different outlets so everything gets a good work out.
