An Update...I haven't been in the Cave as much as I'd like but I have managed to make a few decisions. I have ordered 8 different resistor values between 3.3 and 15 ohms. In addition I ordered the Mundorf Supreme in the 10 ohm version for current use...the others are the version below the Supremes. I thought since I will have three different types of power tubes, I'd buy several pairs so I could tweak the tweeter if needed, in the future.
The two Quads of Russian 6P3S-E power tubes I bought have made it to NYC and should be in my Amp by next weekend...I hope. I'll put in the 70's quad first to make sure they work then I'll store them as spares and use the 60's quad for a few months, at least. Syd's reports have my expectations high.
The problem I thought I had after putting in several Herbies isolation products, seems to have resolved itself. I think it's a combination of my ears/brain acclimating and re-positioning my HR-1s. Someone here had mentioned that I may be sitting in a Null zone and suggested I walk around my room and see if the Bass was more prominent elsewhere. It was, right behind the speakers standing near the front wall. One speaker can't really be moved back but I did reduce the toe-in so it is pointing to a spot 3 feet to the side of my head. The second speaker, I did the same plus moved it back towards the wall about a foot. These changes seem to have increased/improved the Bass response. And pointing the tweeters 3 feet to either side of my head, by using almost no toe-in, has reduced the Hot, bothersome treble significantly and also seems to have increased the soundstage and improved imaging. Until the next report, Mark.
