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.

"The only other electronics I have heard that match Luxman are LFD from the UK and McIntosh from here in the US for sonics and build quality at this price point."

Build quality? My latest version of the LFD Zero Mk III broke. Fortunately the USA distributor is professional and responsive about the matter, but as with most broken consumer goods - it's a time/money waster. My mid-70's tuner is operating w/o a single issue after all these years, and I'd bet it was put together on an assembly line by low-wage working people who were not professors or audio engineers.
This is a followup to my previous post about my LFD Zero with a repair issue:

Received complete satisfaction for my repair issue from the USA distributor of LFD Audio products: http://www.fidelisav.com/

Highly recommended outfit!
Nice to hear.
Plus, he also carries Luxman and Lavardin!
now if only he had Leben....
Byegolly

LFD: I had one for three years with no problems. Sold it this year for 80 percent of what I paid. Replacing it with Luxman.
I've heard the L505. It's really sweet. I've also had the chance to audition the Leben CS-300. I'll stick with the LFD as long as no (more) repair issues ensue. We know different room/speakers/wires/etc. make A/B comparisons of amplifiers unpredictable as there is no place that has all this gear in one room connected to an A/B+ switcher. I'm thinking that because the LFD is aesthetically so very plain Jane (w/o remote capability and the bells and whistles others offer) without the name perception panache - most potential purchasers of the LFD get cold feet and move elsewhere. If I had a relative from Japan that could have brought back a Shindo, Luxman, Leben amp b-e-f-o-r-e I had heard the LFD, I would probably have one. It's obvious I like the LFD, but damn - I love tube amps very much too.
