@2channeljunkie I can't offer any input on the Theta amps; never ran across any. I vastly preferred the MC2500 to SAE and Phase Linear at the time, but found the Threshold Stasis to be a bit more enjoyable with the turntable rig I was using (Magnepan arm, DV23 Ruby, Sota Sapphire). Couldn't afford either, so stuck with my Hafler DH220 until I could swing my Belles Model One.
@g_nakamoto Not necessarily; the 2500/2600 were designed as caged, rack-mount units and McIntosh decided to produce a form that could be used both by consumers and professionals. That's why the fans are speed selectable and can be set to thermostatic control. 602 is strictly a consumer design; glass faceplates don't travel well in Anvil cases.
