Hey Joe or others I just received my Dangerous Monitor ST and was reading Joe Hannigan's Dangerous Music Monitor ST, Monitor SR Field Test-Mix reviews the Dangerous Music Monitor ST, Monitor SR Stereo and Surround Loudspeaker Control Thanks for writing that! You mentioned using the Radio Shack SPL meter (model #3-2055) in the review. Was that this unit? http://www.radioshack.com/product/index.jsp?productId=2103667 Also, I may want to buy a good stereo meter system. Other that the beauty that Dangerous Music makes, does anyone have any suggestions for stereo meters?
