“Hi Rachel,
I just want to give you an update. The tube(s) are doing well. No issues seen and I have about 10 hours on them so far.
I gotta say “wow!” these are deadly quiet, extremely dark but not in a soupy muddled way, they are still very dynamic but the silence is incredible. I am really enjoying these so far and I am sure that they will continue to develop.”
