Luxman preamp into Mark Levinson amp?

I really appreciate all the contributions to this thread. You guys have really helped me. Yesterday I spent about 10 hours driving time and about an hour auditioning the amp. It's home now and in my line of sight as I sip coffee. Yippy! So far it's working purfectly; very statuesque. 

The seller has changed the tubes in the phono stage to NOS RCA's. the rest are origional. The seller also told me that by switching from 12AX7's to 12AU7's the current can be reduced by 30%. The Luxman has both (3 12AX7's and 5 12AU7's). I can look into this later if needed.

The other thing I haven't mentioned yet is that I have a Mark Levinson No26s that needs repair. At some point in the future I will be able to insert the ML solid state preamp for compairison. If I love both they will both be used as I continue to develop 2 systems. The house will alwas have the Wilson speakers as they meet the wife factor standards (statuesque). 

I hope to report on how the two preamps compair threw this system.

Yes i am anxious to hear how the combo goes. If you have any questions regarding tubes, I have run the gammut on these types of tubes. I own a Luxman Eq-500 phono stage which posses the very same tubes. Oh on another note, the Luxman CL-38u and Mark Levinson 23.5 is good match impedance wise.  47KOHM to 300 OHM. 

It's all warming up now. I'm going to give it a good soak before I sit for a listen. I'm excited! Might just give it an houre or so.

Ok, I've spent some time listening. My thoughts are......WOW! The difference between the Luxman and the Audio Research SP8 is huge. I will have to get the SP8 in for service to be fair and I don't think the impedence match makes it a fair compairsion any way. That being said, I think I have landed on a system that needs no upgrades for my ear. The detail in the highs is incredible and the bass is shacking the foor. The system sounds ballanced from top to bottom. I noticed that a tamborine sounded like the insterument rather than a shimmering rattle. It was easy to visualize how it was being played; with shakeing and the taps that emphasize a beat. Beautiful. I could clearly hear the attack an electric base string, the percussion strick of a piano and the breathing of the singers. The sound stage was wide and had front to back depth. Though I am still listening below 9 oclock on the volume diel I have more control of the volume because it is not stepped. The SP8 is stepped and was just oppening up before it got too loud. I think to compair the SP8 to the luxman is a mistake but it is not a mistake to say the Luxman is a great match for the Mark Levinson.
