On the Sunfire Web site, the TGA-7401 is spec'd to 120 amps of current per channel while weighing 46 lbs. I had an e-mail discussion with Parasound regarding their NewClassic 5250 v.2 and asked them how it was possible for the Sunfire to have so much more current than the Parasound while weighing so much less. They said that they would have to "question" the Sunfire's specs on current by weight is part of the equation when it comes to current. For reference, the Parasound Halo A51 has 60 amps of current per channel while weighing 80 pounds. The Sunfire TGA-7401 has double the current capability while weighing about half as much. Are Sunfire's specs accurate or is something up? I am sure Parasound's input on this matter would be bias so I am looking for an unbiased point-of-view.
