When I bought my Luxman L-505f back at the begining of 2004 I almost got the L-507f but just out of my price range.
For the money the L-505f was a great int amp and if I had the money I would go ahead and get the L-505u. I had to sell the L-505f so now I may just keep everything I got and save for the next two years and see what else Luxman may come up with.
One of the things I liked about the L-505f was I used the preamp with a tube amp I had or use a tube preamp with the 505f amp section or just used it as a int amp.
Also the tone controls were outstanding!! They could not make a bad recording perfect but I have too many bad recordings and the tone controls allowed me to adjust the treble and bass just enough to make the bad recordings much more bearable. As always this is my opinion of equipment I have had in my system.
