Give me two weeks. I am suppose to receive my Maestro today and I received my Sapphire XL's three weeks ago. Work has been kicking my ass, but once I break in the Maestro I was going to post my thoughts. First, independently concerning the XL's, then independently concerning the Maestro, then a combination of the two. I also have 25th Anniversary Sapphires I am going to use as a comparison. Expect me to have a pretty detailed review out here by Mid-Late February. I only have about 30 hours of time on the XL's so it's even a little premature to review those bad boys.
