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.

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?

Rosedanny - The 500W and 1000W transformers each have a thin cord. It has nothing to do with the performance, however. Your Luxman is 210W - so it is double, and is therefore more than adaquate. I have the 1000W. A gentleman who bought Luxman 509U new from Japan for $5,000 used a heavy-duty US-made transformer. He was getting a 'hum' because the cords cannot have a third prong/ground-pin. He replaced it with a 1500W Japanese transformer - and there was no longer any 'hum' - dead silent. There are three brands you can use: (1) Nissyo, (2) Kashimura, and, (3) Sanyo. You could have saved more money if you wanted a heavy-duty transformer by ordering one from 'Joynetmall.com'. But you have to pay for the transformer. $2,280 for the Luxman L505U (using pay-pal), and $160 for a Nissyo 1500W transformer (plus shipping costs). That is why I told you to call me. I believe I was the first to order the Luxman L505U from Japan in this manner. I ordered it 20 months ago. None of the Japanese on-line stores will give you the 1500W for free. On the matter concerning the translation of the owner's manual into English, let me look into that.

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?!

Rosedanny - You will not do any damage by using a 1500W transformer. You can use the Nissyo 500W, which is a heavy-duty transformer, for a cd-player. If you order a cd-player from Japan they probably will give you a Kasimura 100W transformer. Now to make sure your transformer has no 'hum' you can test it by turning on the cd player, but do not play the cd. Turn the Luxman on, adjust to whichever input (rca or xlr) you are using for the cd player, and turn the volume up slowly to hear any 'hum'. I recommend testing this with each transformer to find which is optimum.

I live in North America and hence would buy Luxman from the North American distributor.

These units have been factory built to be compatible with our electrical grid.

Moreover the distributor has invested considerable resources to re-introduce Luxman to NA, promote it to the audio press and at trade shows, and build a dealer network, provide after sales service etc.

All those great reviews in The Absolute Sound and Stereophile etc. that help increase market presence and resale value are thanks to the efforts of the distributor (and a great product).

Ordering grey market product at a discount may seem like a deal but it is a selfish act, robbing the official distributor while still allowing you to benefit from their efforts to promote the product and increase its value in their market (and yours).
