r for a preampM-120a w/ Denon 635

I have a Luxman M-120a and was just given a Denon 635-r receiver, I was thinking as using the Denon for the preamp as its also a remote.

Has anyone used this setup? My speakers are the Herseys.
The preamp is just as important as your amp and speakers. The last thing I would use is the preamp section of a receiver. If you're on a tight budget, a passive would be a much better choice.
