Jeff Rowland 2 or Classe 25 for Avalon Eclipse

The Jeff Rowland Model 2 is an amazing amplifier and I would choose it over the Classe 25.

Jeff Rowland model 2 with 100wpc, I think it has less power enough to drive Avalon Eclipse, right or wrong?

The Model 2 has 2 gain settings and it is quite beefy as long as it doesn't have to drive through a black hole :-) The Avalons aren't so critical. The Model 2 is from sound quality definitely a class of its own.
It also has 2 different input impedances, it can be matched with a lot of preamps. Maybe there is a chance to get in touch with the Manufacturer to get a good information about speaker matching?

Just a reminder that the Classe Twenty Five and the Classe DR-25 are very different sounding amps.

The JRDG Model 2 is 75 wpc, the Classe 25 is 250 wpc. If you need the power, the Classe is your answer. Otherwise, the JRDG Model 2 sounds better within it's power constraints. The Classe will play about 5 dB louder though.
Typical quantity vs. quality issue.
