Accuphase e800 or luxman m900u for sonus faber olympica nova 3


Hi all
Currently I have an aw250R electrocompainet equipment and I pre-loaded 4.8 mk2 with some sonus faber olympica nova 3 and I am thinking of improving my amplification.
I like the accuphase E800 and the luxman 900 preamp and stage.
They offer me the C900 exdemo at a good price, about 8000 Eur and giving my previous would stay at € 6750, they offer me very little for my previous when it is not a year old, it is practically new and costs 3 times more, you think it is worth it the change.
The idea was to take the previous luxman and leave the electrocompainet stage for a while until we could go through the luxman stage.
I would also value other brands that you would recommend if with this I make a leap in quality, I have also looked at pass, I do not know the model, but it may not go wrong with my boxes.
I appreciate your opinion, I have to make a decision soon.

Thanks a lot

The Luxman 900 "combo" can be purchased for less than $20K. I do not like the sound - it is too smooth and should I say "musical"? I am a tube guy and I hated this combination. 
Gerry, Im talking about BRAND NEW...not used prices. Dealer COST on the combo is 21K.
Half of my collection is Tube Amps...7 of them. Variety is the Spice of life.
As an alternative you could look at Karan Acoustics KA S400 or KA S600. VITUS AUDIO SS-025 or VITUS AUDIO SS-103.  I heard a lot of good staff specially about Karan Acoustics.
Hello,
If these are the only two companies your looking at that is ok. For $10k Ayre sells the KX-5 preamp. Instead of an attenuated volume on the inputs like these companies do it has a variable gain stage on the back end. You have a total lossless sound regardless of volume. You get a little warmth like a tube preamp but all the fast detail of a SS. I have tested this on several amps and they all sounded incredible due to the Ayre preamp. I know Jay’s did not prefer this to the Luxman on the Luxmin amp. He also did not buy any of the Luxman product. In fact he still cannot make up his mind. If you can try the Ayre preamp. It’s awesome!  This is my endgame gear. I have heard Ayre on Dali, KEF, Revel, Soliloquy, Maggie’s, coincidence, Theils, and several others. They all sound better. If you are in the Chicagoland area this is the closest dealer that I know of. https://holmaudio.com/I like how they let me try stuff at my home. This is the most important thing for audiophiles. 

HSHIFI,
What do you mean Jay didnt buy any of the Luxman product? He certainly did. He purchased it from Suncoast Audio in Florida. I still have a Brand New in the Box Luxman 900 Amp that I got from Jay...he had purchased this amp at least 3-4 times before From Mike at Suncoast.  Dont talk about things you dont know about.  As far as Ayre products go....I had a VXR Twenty amp and the TOTL Pre-amp KXR-Twenty.  Know the worst thing about Ayre gear....trying to re-sell it especially after Charles died. NOBODY wants it anymore. You Buy it be prepared to be stuck with it...so you better love it.  I had to trade my KXR-Twenty to Jay just to get rid of it!!!
