Tube Amps: CAT JL3's vs ARC Ref 300's


Can anyone provide a comparison of the two amplifier's based on personal experience?

Raquel, the CAT JL3s are rated at 150 watts, not 200. Real world performance, however, seems to belie this rating.

Sorry for my ignorance here.Are the CATs pentode or triode?If pentode,then Atmasphere makes a case for the Triodes sounding better. I know these(Atmosphere) are OTL.I own neither,but may be interested in future configuring.Thanks,so much!Also,maybe someone could,briefly,explain the diff between all three types.
