Luxman L505u . . . why not?


I'm getting close to pulling the trigger on one of these--an upgrade from my Rotel receiver. Before I do, I'd like some perspective from the learned A'gon community. First, will it be a significant upgrade from the Rotel? What kind of sonic improvements can I expect? Second, why shouldn't I buy from Audiocubes II? http://www.audiocubes2.com/brand/Luxman/product/Luxman_L-505u_Integrated_Amplifier.html
I know On a Higher Note is the official U.S. distributer, but my budget pushes me towards the less expensive purchase option. Third, regardless of where I purchase it from, it will need a transformer to boost the power to 220. I don't know anything about the possible effects this might have on sound and performance of the component--can anybody speak to this? Is it possible to have the piece modified to accept the U.S. 110 current? I want the piece because it meets my requirements for an integrated: it's at least 100W, it has speaker A/B (I've got speakers in the kitchen and the main living room), it's got a great phono section (I play 50% records, 50% CDs), and it's got a headphone amp. Those are the features I want in an integrated. Any advice, suggestions, dissuasions will be appreciated.

I have a pair of Harbeth SHL5 speakers. Anyone had the chance to try L505u or L550 with those speakers?
Merlocpm, there's a nice guy on here who has, maybe he'll chime in....not sure about the 505u, but he has the 550 and 590, which he seems to love...great bass, tone.
Merlocpm ...

I'm using Hl5s with the lux 550a II. This after a series of amps, including bi-amping.
The Lux-Harbeth just sings. It's incredible.
HI Jabas, care to share about what others you've tried?
Don't be such a tease!
how old is your lux 550a II?

Thanks

Wow! This thread sure morphed!
Well I bought the sucker, and he's in my house hooked up to my Vandersteen 2ce sigs. It's all I had hoped for! Better resolution (than my Rotel receiver)without being harsh. More punch. "Fast" is the adjective that keeps coming to mind. And it has lots of power--clearly way more than 100W per side. The phono stage is exellent. I'm hearing things anew from old records. But none of the detail and attack comes at a sacrifice of musicality. Great texture to the strings (very much like the LFD I heard once). It really makes my Vandersteens jump and groove! The only negatives are 1) the transformer was smaller and lesser build quality than I expected. I've already upgraded to a Kasimura TI-19. 2) No English translation of the owner's manual. Audiocubes won't supply one, and Luxman won't supply one becuse Audiocubes isn't an authorized Luxman dealer. If anybody out there can help me with this I'd really appreciate it. I'd even pay someone who has one for their time to copy it and send it to me!
Anyway, thanks for all your responses. I recommend this purchase and the seller if you're considering a Luxman.
