Bart,
Do be careful before you universally recommend the Kraft 250 over the CAT JL2.
The Kraft 250 works for YOUR particular system - the CAT JL2 was always a misfit for your system because of the flagship Avalon speaker that you have. The CAT JL2 being a tubed power amp never had the ability from the get-go to ever drive your speakers. Thus, with the Kraft 250, you are hearing, maybe for the 1st time ever, what your speakers are capable of. You can thank Jay for this turn-around in your system.
I do not know much about the Andra speakers but it is entirely possible that they are beasts to drive (just like the Avalon flagship speakers) in which case the CAT JL2 is the wrong amp for the job. Yes, it'll give you good sound but I do not think that it would do justice to the Andra speakers - I could be wrong but this seems to be my opinion from what I have read & heard about these speakers. You would need a much higher wattage amp - if you want to stay in the tube domain then a VTL MB450, MB185 or VTL MB750 or a TRL 400, Wolcott Presence 220. If you want to switch to a s.s. amp then the Kraft 250 would do very nicely. Like Bart wrote, it is unlike any other s.s. amp you might have heard. Best of both tube & s.s. worlds + stable to 0.5 Ohms.
