Your speakers are designed by one of the more known DIY designers, they are definitely timed and phased aligned, but looking at the components used, you definitely have a very detailed speaker that will show all flaws elsewhere. Your 8008 and your w4s are both known for being fairly accurate also. I'd try to borrow a couple of good Pre's... ss and tubed. A reputable dealer would let you put one on a credit card and refund it after audition. Cables can contribute to dryness. You need to find a good dealer or better yet some helpful audiophiles that live around you to help you try a few different items in your system. Post what part of the country that you live in. Lastly, personally, I would not get rid of any of the 3 components that I listed without experimenting with a few switchouts first... Good Luck,
