TBG, that is interesting that you still possess the H-Cat, that was an interesting thread in itself. Definitely would love to hear your system in Texas, my sister lives there and have been to Texas one time at Fort Worth many years ago, parents were stationed there.
Your cabling and grounding units, making up half the cost of your system, seems like a sound investment and it may not be that uncommon but I personally cannot make that same claim but do recognize the importance of these investments in sound quality.
