Please post a detailed report after your Luxman arrives!
I have had my L-590A II for a week now and I not only am very pleased but pleasantly surprised. I say surprised because it far exceeds my expectations.
My main goal from switching from my McIntosh MC402 and C46 was hopes of a better match with my speakers; I have heard my speakers at a show where they sounded better than I had at home, by quite a bit frankly. My thoughts of change was based on various setups I know the founder used with them.
The clarity/transparancy of this amp is far greater than any others I have owned and the bass is far superior to what I had with the Mac gear, in fact both the bass and transparency are simply incredible, I cannot over state either enough. One could easily confuse the two setups as having the reverse in wattage.
There a songs even played via my tuner where I simply amazed, including hearing details I'd never knew existed.
The Mac gear is laid back and I have accused some past speakers of being recessed in the midrange, where I now think it had more to do with the Mac gear. (I sure would like to have some past speakers back to hear with this amp.) I don't like sounding so critical of the Mac and that isn't my intent, it is just that the Luxman is that much better. (I usually like to say here, IMO, but man, there is no denying that the Luxman is better. Now there "may" be some things that some would prefer with the Mac gear, but that doesn't negate the obvious.)
Great dynamics with the Luxman and I was hoping to get more depth using Class A, think 3D, which it achieves.
The L-590A II is a great piece indeed. I will say that it is very revealing and if one has speakers on the bright side, it'll show it and I suspect it could be too much for you. Pair it well and you will be rewarded.
