Luxman preamp into Mark Levinson amp?

Thank you both. I'll look up info on both these amps to see how they compare to the ML for a sense of referrence.

The Mark Levinson No. 23.5 is a true voltage source. It successfully doubles power from 8Ohms to Ohms (400W). This is mandatory for the WATT/Puppy, which drops to 2.1Ohms at 80Hz. A weaker amplifier would suffer from current limiting or significant frequency response deviations in the mid-bass "thump" region.

But gain matching will be a headscratcher, as the amp only takes 1.41V to get to full tilt so you may run into gain clipping issues where you can’t get the Preamp volumee knob past 10 oclock on the dial

The Luxman can output 37V, but the Mark Levinson hits its maximum possible volume (clipping point) at only 1.41V.

Thanks for your input Kofibaffour. I wish I had more of a background in electronics. I try to coble information from experiencial evidence and anicdote. Not the best way to go. I connected an Audio Research SP8 to the ML and it was getting loud at 4 clicks of the attenuater. The AR can be stepped down internaly by 6db according to one source (the AI robot misinformation streem). Apparently the Luxman may have more adjustability regarding gain and sensitivity. The robot also suggested the problem may be resulting from 2 volts delivered from my McIntosh MCD 7007 CD player and reccomended using a passive attenuator between the CD and Preamp.

I just went thru the same with a Datasat processor and a McCormack amp. Datasat Preamp out is HOT, so I purchased some Harrison Labs FMOD 12dB attenuators. took some doing to rebalance the speaker array but it did the trick. 
 

I formerly had the 23.5 and it is a glorious amplifier. Always wanted a pair of puppies. Nice setup, let us know how it turns out. 

Thank you Seismic. I haven't gotten it out yet but my attenuater is a single pot volume so it will be simple. I suppose placing the attenuator between the amp and pre makes more sense than between the CD and pre. Thanks for your info.
