I have reviewed for 20 years for Dagogo.com and over that time have built hundreds of systems with most genres of components and speakers. While I cannot visit everyone's home who wishes, I can tell everyone plainly what my assessment is of their system building methods, which influences the sound quality.
I have written a book The Audiophile Laws which details the factors influencing system building, reveals the mistakes that many make, and corrects how to advance an audio system.
If I may, baclagg, offer a suggestion based on the images and description of your system. After all, you half-invited me to come over. So, in lieu of a visit, I offered what I can in assessment of your system. (I have a pretty good idea of what your system's basic characteristics would sound like, but no one can tell the fine characteristics without hearing it, and certainly it would be a mess to attempt a discussion of such fine attributes sans listening session).
You are using an ad hoc mix of cables, which is a mistake in system building. Anyone who uses a mix of cables has no idea what they are doing; it's nothing more than guessing at it. The only proper way to advance an audio system through cables is to compare entire sets. I suggest no less than three sets of power cords, interconnects, and speaker cables, and if available, digital cable, etc.
This is quite a bit more effort and potentially much more costly, but it is the means to select cables that will elevate the system on the order of changing a component. Most audiophiles do not wish to invest that much time and money. If you were to compare sets of cables, you would elevate your system's sound dramatically.
I explain in my book how I arrived at that principle and many others through actual system building, not the received wisdom of the industry and community. In practice, many of my Audiophile Laws encourage the audiophile to do the opposite of most reviewers.
