Regardless of your tt config, you've got some serious time smear going on with some of your ics and scs. This will create harsh, grainy, and/or glaring highs and rolling thunder/ill-defined sloppy bass.
Try auditioning some Audience Au24, Speltz, Audio Tekne, Zu or possibly a number of other cables to compare with your current ics and scs. You might find the difference to be far from subtle and might resolve at least part of your problem.
Also, perhaps it's not your tt. Try listening to your best cdp and compare.
I've never listened to a system with your line conditioner but I've heard relatively good things about it. However, it looks like you have just one LC. If so and if you have both digital and analog components connected to the same line conditioner try disconnecting all the digital from the line conditioner.
Very few line conditioners provide bi-directional filtering and I doubt yours does too. All digital components induce digital noise back into the AC (bi-directional) and will induce that digital noise into every one of your other components including other digital components.
Digital noise will sound shrill, glaring, and harsh and it's compounded with every component it infiltrates and by every component that generates it.
Even if the mfg'er claims the LC to be bi-directional filtering, I'd still remove the digital components to see what changes.
-IMO
