Help with fatiguing sound in my PC system

I replaced my Halo Pre and Denon changer with a PS Audio DL III. I run lossless music into it from iTunes on a PC (Windows 7 64bit, core i7, 16MB RAM), I use a Pangea USB cable into a MF V-link, then go into the DAC with a Wireworld ultraviolet coax. The increased detail, clarity, resolution and extension are remarkable, but so is the amount of listening fatigue. The highs are too much, but the music sounds muffled if I add the pre-amp back. My system is profiled in the link below. I have some ideas, let the voting begin:
1 - buy an offramp or a pacecar (can't afford it!)
2 - use better USB/coax/interconnects/speaker cable
3 - apply acoustic treatments to the room
4 - use a software player (Jplay) that sits on top of iTunes
5 - buy speakers with different tweeters (Quad 22L2/Focal 826v, this is happening, but not any time soon)
6 - get a better amp (McCormack/Odyssey, distant future)
7 - tweak Windows 7/iTunes settings (WASAPI exclusive mode?!?)
8 - adjust speaker position/toe in (already did this and it helped a little)
I am thinking about trying #3/#7 next. Ideas? Thnx in advance.

"Is there a re-clocker out there that I am missing?"

Depends on what you want to reclock. Here is one that is more for Sonos and AppleTV etc..:

"there are probably better ones than the MF V-link I bought. Audiophelio, Halide, Stello. Not sure one of these will make as significant a difference as a new clock."

They will and there are better ones if you want to do USB. This makes the difference between harsh digital and analog SQ.

I definitely want to do USB, But the synchro mesh looks interesting, will it work with a mf v-lnk, does it accept 24/96?

You're referencing speakers with metallic tweeters, a solid state DAC that is known to be bright (similiar to the Benchmark DAC1), and you're driving your amp directly with one of those types of DACs?

Really? I don't find the PS Audio dac bright sounding at all and have never heard it described that way. In fact all the accounts I have read are opposite. Have you any experience with the DLIII?

Realremo - The Synchro-Mesh is not the right solution if you want to stay with USB. It is a resampler.

The right solution is to upgrade your USB converter. The Master Clock is in there, so it is the right upgrade. Bit perfect too.

I bought the DL III because of the sonic character described in pretty much all of the reviews - warm, big soundstage, with a very good handle on low end frequencies. The improvement in SQ after running the signal from my Denon changer into the DAC was noticeable, there was no listener fatigue. But leaving the changer and the pre amp completely out of the signal chain blew that improvement out of the water, yet produced listener fatigue. The pre must have been rolling off the highs somehow. Looks like my search is not over! I might sell the Halo to fund a USB converter upgrade...
