Kiza -

With all due respect, I find your assessment surprising. For 18 months, you have been changing amplifiers to find the best sound. You have owned: Rotel, Plinius 9100, Luxman L505u, Rowland, and the NAD 275BEE. When you auditioned McIntosh 6300 and Luxman L505u connected to a pair of B&W 801D speakers, you thought Luxman sounded alot better, right?

In Japan, it costs $1,900 to purchase a Luxman L505u. In comparing the 70's Luxman R1120 vs the new Luxman L505u, the new Luxman sounds much better. The higher end Luxman 507 and 509 will sound even better yet. I used the 507 with a step-down transformer for two months. Now, the unit is operating in North American voltage. This is achieved by changing the jumper inside the unit to 115v. Also, you can set it for 230v (which also requires the fuses be changed). After comparing the sound using the USA 115-volt operation and the 100-volt step-down transformer, I could not detect any difference.

In the end, Luxman, McIntosh, and Accuphase are the top amps in the world - no question about it. Your NAD is produced of Chinese components. I have doubts that it will last 30 years. Here are the top three tiers of INT AMPS: (1) Luxman L509u; (2a) McIntosh MA7000, and (2b) Luxman L507u; and (3) Accuphase E450. These results can vary based on your set-up (speakers, etc). To optimize sound quality with a Luxman, use four tower speakers with the unit: two in the front, and two in the back with A+B running. This is my personal opinion.
