What to add or change for my system?

Even more great suggestions!

I do have vibration pods for every component.  Also have Pangea power cords for every component going to the Furman, and a massive cord from the Furman to the audio receptacles.  I don't have a dedicated line from breaker box to wall, but that isn't really possible in my case.

I made cable risers from Styrofoam squares that I painted black and put a felt pad on the bottom to protect the wood floor.  Cables rest on top.

The room is not dedicated to audio, it's our living room.  It's 15x16 with one of the 15 foot sides open to our dinning room, other side is a fireplace.  Ceiling is 8 feet, sloping both sides to 12 feet in center. Speakers are 8 feet apart, 3.5 feet from the front wall, and 4 feet from the side walls.  It's a pretty big room.

I do have a decent music collection all on hard disk, and I listen to Tidal a lot.

I like the idea of room treatment.  Because the MLs are dipole, would a 2x4 absorption panel directly behind the speakers work best?

Thanks guys!!!

Does your system benefit from the cable riser?...mine doesn't

Stringreen, I'm not sure. But the risers were only about $20 to make and took only the time for paint to dry. I bought the styrofoam blocks from Michael's for $3 each, then a can of spray paint and felt pads from Lowe's. They look nice enough, and importantly really help eliminate dust bunnies.

Not to start a heated debate, but what about changing the fuses in the Plinius?  Pretty easy as all fuses are accessible from the back of the unit.  I've read pros and cons on this, as I'm sure all of you have too?

You should check out the thread on the Synergistic Research quantum black fuses. They seem to get tons of raves.
