No-one talks about Rowlands anymore

I've already stated that I really love my JR 625 S2 amp. I hear a lot of talk about how bad their preamps are, but to date I haven't found anything to replace my JR preamp within its price range. Maybe I'm one of those people that enjoys the Jeff Rowland "house" sound or maybe there's such synergy with Rowland amps and preamps that makes it very hard to find a better match?

I'm trying to find a way to compare my Jeff Rowland 625 S2 amplifier to the Luxman M900u amplifier. They are similarly priced and the comparison should give me an idea of where the 625 S2 fits in the high-end world. 

It’s my understanding they do very well overseas. I have the Class AB 625 S2 and have compared it to several amps. The only amplifier that I preferred over the 625 is Absolare mono-amps. Rowland doesn't do marketing the way some very popular high-end manufacturers.

I submit Rowland just doesn't put a lot of money into marketing. I've talked to Mr. Rowland several times and he was always knowledgeable, helpful, and very kind. His customer service is outstanding.
