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.

While the digital audio chain can certainly contribute fatigue, what I've personally found is that unbearable listening fatigue is more likely to come from the speakers, the amplifier, and the room.

If you are not planning to replace speakers and amplifiers for some time, then short term fix may be the room.

Does your room exhibit much in the way of slap echo?

Yes it does, and acoustic foam is next on my list. I have carpet on the floor, but the walls and ceiling are gypsum wall board (sheet rock). The room is 12x12x8. I'm planning on putting up about 100 sq ft of acoustic dampening. I have also researched the audiophellio, read some reviews, and tonight I'm more in the "save for new speakers" camp. Still researching the stello. Tomorrow night or Sunday I'll have another idea, but the acoustical treatments will happen regardless.
Whatever I do, nothing can help my 1980 "Boy" CD, I'll have to buy the 2008 remaster.

Realremo - be careful not to overdo the absorptive materials. If you already have carpeting, then you are already close. Too much will kill the liveness.

Just deal with the side-wall echoes by using a small mirror to determine the best points of attachment. If you see the tweeter in the mirror from the listening position, that is where you put them. Never put absorbing material behind the speakers. Use scattering devices instead.

And BTW, this will not fix the harshness. This is due to jitter mostly IME.

I am running a Asus notebook running Windows 7 64bit and J Rivers 17. The usb output from the notebook goes to a Musical Fidelity V-Link via a Wireworld Starlight usb cable and a Wireworld Starlight coax cable from the V-Link to a Wyred Dac 1. The sound is extremely detailed, NON FATIGUEING, and musical. All my hi-rez files sound incredible. All my files are ripped into flac and output the player in waspapi mode.

First thing I would do is ditch iTunes and try the J Rivers 17 Media Player. You can use it free for 30 days and then decide if you like it. It blows away iTunes by a wide margin.

Here's a summary of my experience:

- A system with a murky source may not exhibit fatigue, but once you give it a very revealing, resolving signal, it may become quite fatiguing.
- Improving the quality of the source, like what the Off Ramp 5 is able to do, makes a difference. But to me, it makes things sound better rather thank make things bearable. As always, your mileage may vary.
- It's not just speakers, it's also the amplifier and how the speakers and the amplifiers work together.
- Synergy is important. And certain components will bring a certain character to your system. For example, a Leben sounds warm, lush and beautiful. Never heard anyone describe a Leben or a Shindo as fatiguing.
- If you're going to buy a USB SPDIF converter, the Off Ramp is markedly better than the Audiophilleo.
- The hobby gets more expensive when you want ultra resolving, natural, musical, non-fatiguing, full of body, and transparent all rolled into one.
