Thanks, dbarger. Very interesting.You have some nice amps! How would you compare those big Luxman separates to the LM-845 Premium? The latter has been on my radar for a while, though my reduction in racks from 4 to 3 to accommodate the girth of the CWs would make it difficult to find room for two large chassis.

Slightly off topic, do you ever run the LM-845P with an external preamp? If so, what are your thoughts? I've read the preamp circuitry remains involved even when supposedly by-passed, which is off-putting to me, perhaps for no good reason. I'd likely want to run it with my VAC pre, mainly because it has a sweet phono stage.

wrm57, exactly the differences you might expect. The 845 is fuller sounding, the luxman a bit more transparent. The luxmans are the first solid state combo that is a keeper for me. I have mostly tried passlabs, first watt, ayre, parasound, etc. usually listed them or returned them within a week or so of receiving them. The lux’s have all the transparency and detail of the best solid stated but a bit of the naturalness of tubes.
Yes I have used preamps into the premium. The lower end amps (518) benefit greatly from that, but not this, IMO. It is all transformer coupled and pretty well voiced as it comes. I will also say that upgrading the 845’s to elrogs has a much greater impact on the 518 than on this. As supplied it sounds great!
Also, to elaborate a bit more on the satisfaction level with the lm210ia, it is equally satisfying, but in different ways.  It has different cards to play, mostly in directness and nuance.  It is a keeper also.  In fact I did order a pair of western electrics for it today.

So far I have used a music reference RM9 II (125 watts), Granite Audio monoblocks (60 watts), NOS valves ST-45 (40 watts), and now an Aric Audio Super KT88/150 SE with the cornwalls.

The 14 watts/channel of the Aric amp have been the star of the show. This combination is pure magic.

Supposedly you will hear a noticeable change...for the better...using the Line Magnetic 512 Preamp with the 845 Premium. Hope to find out one day for myself.

@ozzy62: If you come across a Music Reference RM-10 Mk.2, consider snapping it up. That amp was Roger's favorite push-pull amp of his design, and is a little jewel. He made it in a few different incarnations: originally 35/35w in Class A/B, later 25/25w in Class A. I think I have that right, but if not @clio09 will correct me. ;-)
