Just a quick note to let fellow Canadians know that Radio Shack currently has a sale on their digital SPL meters...$49.99 CAD (that's $31.00 USD). The regular price is $89.99 CAD. I picked one up last night and did a quick calibration using AVIA. Worked great (yup...75db using Denon 3802 test tones = 85db using AVIA). A bit unusual trying to dial in the 2 surround back channels as AVIA is only 5.1 and I have a 7.1 system, so I had to use the 3802 for those channels. Not a problem.
