Hi Paul,

Would you be kind enough to advice whether the extra $ difference between the 505u and 507u is worth it ?
I know the wattage differs by 10watts but i'm almost sure there is something else that differs in the two in terms of sound quality ?
My guess, the 507u is more refine than the 505u.
I'm familiar with accuphase and LFDs having tried them numerous times.
I look forward to auditioning the Luxman soon.

thanks...
If you look at the importer site you will see that it has lots of "ness" to it. It didn't compare well to the Ayre integrated I had at the time or the McIntosh 6500 IMO.

Luxman is trying to win back the mid to upper end high fi and IMHO they are doing it. Look a little deeper into the line. The 505u is a hopeful unit. "I really like your personality but..."
The L505u is an interesting piece of audio equipment. I decided to go that direction due to cabnitry constraints that prevented me from using a medium power tube amp. I bought the L505u on reputation. My speaker system is extremely hohographic with exceptional depth perspective. At least that is the way it sounded with the tube amp I was using previously. Right out of the box, I couldn't believe how congested and "thick" sounding the L505u reproduction was.I expected a little better start up than that, however, in as much as all audio equipment needs to go through a "break in" period, I decided to be patient. Well, after 200 hours I was told that the reproduction would totally open up; equivalent to opening a door. Yes there was an improvement, but only slight. I now have about 1000 hours on the piece and have also tried a variety of tweeks to see if the sound character would change or improve. Agreed, it has improved somewhat but not to the extent I expected. The sound reproduction is accurate and pleasant but nowhere near that wonderful "holographic" and totally open reproduction I experienced with tubes. Interestingly, I am using the same pair of speakers with another tube based system I own. God, what a difference. Everyone who has heard both my systems agrees. I have discussed this issue with various dealers and members of the CAES (Chicago Audio Engineering Society.) Generally speaking, most agree that this is, for the most part, one of the primary difference between tube based audio and solid state. Be that as it may, I guess I am not totally enamoured with the L505u. Lovely build and wonderful features. I wish the sound matched. Unfortunately I really can't afford to experiment with other solid state amps.
At least you still have a tube amp. I very much wanted to move back to solid state and so far my ears haven't allowed it. Next up is a Hegel H200. I've already come to the conclusion that I can't ever sell the tubes
I have had the 505u since 2009.It was purchased new from a dealer in Japan.This so called grey market amp has given me nothing but great entertainment.Saved a ton of money and paid zero import fees.If have recently acquired the service manual and changed it over to 120 VAC.Quite a simple job actually.The 505u's from Japan are multi-voltage.
I do remember reading somewhere where an individual had claimed that the Japanese models had hand wound transformers and were 100 VAC only.Anyway,if someone out there wants to change their amps input voltage,let me know.
