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.

Thank you all for your thoughts. I did contact On A Higher Note, and yes, I would have to use a transformer if I bought from them. Thanks AudioFeil; those are some important considerations.

Jaybo. Could you elaborate on this? Why, specifically, chould I give this more thought?

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.

They sent me the Nissyo NDF-550 transformer. It's not what you descibed in your email (size of a bag of sugar), more like a box of tea (3X4X3.5) but heavier. And build quality of transformer does not match Luxman L505u. The fixed cord from the transformer is thin like the one from my toaster!! So . . . I look forward to doing it right with a higher quality tansformer. Too bad because I was under the impression I'd get one with a higher capacity. They did offer a slight discount ($40) on the Kashimura, which I appreciate. Any clues as to where I can find an English owner's manual?

I guess I spazzed and jumped the gun with the transformer. I'm not really savvy about wattage/voltage numbers and thought the higher wattage transformer would allow more headroom for the amp's fluctuations in power (I'm way out of my limits of understanding here). I made my decision based my understanding of some posts that explained this. Also, the Nissyo didn't have a housing and looked industrial, while the Kasimura looks to have better design and aesthetics. Please tell me at least I will do no damage by using a 1500W transformer?!

Hey Nolitan, I have heard both the LFD and the Luxman. The LFD was driving Harbeth speakers and sounded rich and detailed. I remember hearing the texture of the strings in an orchestral piece. I only listened to the LFD once, at a dealer's house, but that was my impression. What drove me to purchase the Luxman was the added features (you can see what I wanted in an amp at the top--I'm the one who initiated this thread). The LFD is pretty bare bones. Fortunately, I've found that the Luxman has a similar sound: rich, warm, yet detailed, but produces a bit more punch. I listen through Vandersteens, and the Luxman has shown me that when properly driven they can be fast and lively without losing their musicalty. Needless to say, I'm very happy with my L-505u

Oh no here we go again . . .
On a different--personal--note, I'd like to say that I'm no longer a dummy regarding voltage/transformer in my initial posting. At the time, I thought Japan was 220 like Europe, but I was relieved to learn just before my purchase that the transformer converts down from 117-100. I can confirm what Renjy651 says about the consistent, clean power offered by the transformer. I've really enjoyed reading the discussions comparing the L505u to the L507u. Fortunately, it will be a long time before I feel a need to upgrade from the 505u--I'm going to concentrate on building around it!
