Thanks for the invite. Where do you live?
Nice photos, I just sold my Khorns about 2 years ago. They were being used in our computer room and I found they were just sitting here being unused and one of my customers offered to buy them so I let them go. I wish I hadn't as I'm now using some vintage University cornerhorns upstairs although they don't have to be used in the corners. I believe the speaker was called a C6 and in 1958 before stereo this was sold for $538 which was a lot of money back then. They have a nice tone but the Khorns were more dynamic.
I just posted some photos of my main room in the gallery here although the photos are almost 2 years old and I have made some changes, now using a Tom Tutay Transition Audio design 12SN7 based preamp with some Mundorf Silver/Gold/Oil caps
seperate power supply using 6X5 rectifier.
The speakers in the photos are the best I have ever owned. They incorporate the TAD 1601A woofers for the bottom end with a JBL2470 Martinelli version for the mid and a JBL 2404 for the tweet. Very dynamic, I guess I'm just a horny kind of guy
BTW, your Loesch preamp has some beautiful layout work
