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

Lalitk,
Not sure what dealers you are using but your claim that an Accuphase E800 costs more than the Luxman 900 Combo is ridiculous.  I purchased my E800 for $12,500. In Canada I could have gotten it for $1000 less.
Please let me know where I can get the Luxman 900 Combo (Which retails at 35K now) for that kind of money (Or less as you claim) and I will buy a 2nd set today.
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.
