Digital Coaxial Cable 75 ohms choices

to redkiwi: One thing that improved my Data III as much or more than the Digital Lens was damping the outside panels with bags of lead shot. The Theta panels are so large that loud bass passages set them vibrating via coupling through the air. ( I use Zoethicus stands on a homemade air bladder floor)

I will try that plsl. I have already attached damping to the panels of the DAC, but they need all the help they can get because the transformer does not like the 50Hz supply here.

I also removed the feet and made a "sand tray" of lead shot in doubled heavy duty industrial polyethelene bags that are just the size of the bottom panel with just enough space open for the vent slots on the right side. The feet mount to the inside of these slots and the whole bottom panel rests on the lead shot sand tray. There are similiar bags on top and smaller bags attached to the sides and back. I used a total of 80 lbs of lead shot. I play a lot of bass heavy music with Dunlavy SC-V's and Sig Tech DSP correction that gives me flat response to about 25 HZ. The Theta Data III panels really vibrate due to their size and relative thinness at an SPL of 85 or over. You may not need to be as drastic but it is easy to lightly touch the panels during loud passages and feel how much they are vibrating.
