Got the SP20s today. NICE units.
I'm going to give them a few hours to burn in before I start looking at the numbers.
I see why people say that 1.7TH isn't realistic. Mine are steady at 1.55 after an hour with the standard settings. I'll play with those a little later in the day when I have time.
I'll say this though, the QUALITY of the boxes is superior in every way.
