Replace Silver interconnect cable , please advice

Just to be sure nothing simple is being overlooked, are you sure that the new speaker cables are connected with the same phasing? If the cable on one of the two channels has + and - reversed relative to how the cable on the other channel is connected, it would produce the symptoms you've described.

Also, if one of the XLR interconnects is miswired internally the same thing could happen. If you have a multimeter, check that pin 2 on one end is connected to pin 2 on the other end, and that pin 3 on one end is connected to pin 3 on the other end. If pin 2 at one end were connected to pin 3 at the other end (and vice versa), on the cable for one of the two channels, it would account for the symptoms you've described. If you don't have a multimeter, try reversing + and - on one of the speakers (or on an amplifier output) and see what happens; doing that would compensate for a reversal in an XLR interconnect.

Metralla, good job spotting the system description Pelo has just added, but the link you provided is to someone else's system. The correct link is:

The pix in your system description are very helpful, Pelo; thanks for putting them up.

The biggest problem I see is the short distance between the speakers and the wall behind the listening position. First, it looks like there is about a 4 or 5 foot distance between the listening position and that wall, which will produce a suckout in the deep bass region centered at about 60 or 70 Hz. Changing the position of the sofa relative to that wall will vary the frequency and the amplitude of that suckout, and experimenting with different positions may help significantly, although inevitably some compromise will result.

Second, I'm not sure that you are sitting far enough away from the speakers for their three woofers, two of which are in the lower half of the speakers, to blend properly with the mid-range driver, which is near the top.

Third, the close proximity of many reflective surfaces isn't helping imaging and soundstaging.

It appears that more space may be available at the far end of the room, near the window blinds that are visible. If practical, you might consider re-locating everything down there, so that the speakers are aimed along the room's longer dimension.

I see in another thread you've just started that you are replacing the Focal Electra 1038 Be II speakers (15 3/4 inches deep, 49 3/16 inches tall, 112 pounds) with Focal Maestro Utopias (30 5/16 inches deep, 57 7/8 inches tall, 256 pounds).

Hopefully you've chosen a different location for them in the house than the one shown in your system description photos, that we've discussed as being problematical even with the much smaller Electra. If not, unfortunately I think you are going to be disappointed, and the question of amplifier compatibility that you've raised in the other thread will not be the major issue.

Excellent advice from Tboooe, IMO. Also, I see in your system description thread that you'll be moving to a different house in a few months. Hopefully that will provide a much better acoustic environment for the speakers than you have now. I would suggest slowing down and not investing a great deal of money in trying to optimize the system until that time. Otherwise what you may end up doing in the meantime is making changes that band-aid room acoustic problems, but won't prove to be optimal when the speakers are in a better environment.
