Thanks for your kind words. Actually, I built the cabinets flanking both sides of the fireplace for media storage. The freestanding cabinet in the back of the room is a Japanese antique stepped tansu containing one of the subwoofers and it is also used for wine storage. The cabinet with the sink in the back of the room was built to match the stepped tansu. The upper cabinet is also used for media storage.
I second Zephyr24069's comments. A beautiful and impressive system and setup.
And thanks for the nice comment you left for my system description. Looks like we both have Eames chairs in our listening rooms -- great minds think alike!
