That's brilliant. :) I count 6 primary wires on the transformer so this thing can be wired for use anywhere in the world.

I wonder if the Japanese version also has primaries like that.

Having separate versions for domestic and international markets is quite common over there so it wouldn't surprise me. Goes of to hunt for pictures in Japan...

The only internal picture I could find was from the brochure and it is tiny. I do believe that there are more then two wires on the primary of the transformer.

Unlike the US version, the Japan version sold on "On A Higher Note" seems to be grounded. I've also had no luck finding internal pics of the Japan version... =/

Directly from their site:

Most Japanese gear for their domestic market isn't grounded since there is no standardized ground connection over there. The gear is double insulated instead (so a live wire can never reach the chassis).

This is the largest one I've found. It's quite clear though that there is a lot of wires entering the transformer on the right. That means the amp should be easily configured for 120v and 230v use.

So, does this mean that as easily as a few snips, that is all that is needed to make this amp playable with US 120V?

Yup. The only thing that has to be verified is which lead on the transformer is which but that is easily done with an ohm meter.

screaming oranges,

thanks a mil for posting the english manual. only the japanese manual was in my box.

Any of the owners out there tried the Balanced inputs to test for sound quality degradation when converting to SE over RCA all the way through?

Nothing in my rig is balanced, so I have no way to test this.

Yes that would be interesting to know. The P-200 does not have balanced inputs as far as I can tell from pre production unit pics. Not sure what balanced would do for you in as there are no balanced outs for balanced cans. My "reference" big rig with speakers is balanced all the way to the power amp. Doubt I would be able to tell the difference if I changed it all back to SE. Too much trouble to find out.

I sent OAHN an email regarding the P-1 and the P-200. Philip said:

"While the P-1 was recently discontinued, as Luxman were unable to source the parts to continue manufacturing. We are expecting deliveries later next month on a more inexpensive model the P-200, which is also a Class A design and delivery 80- 85% of the performance of the P-1 at about 60% of the cost."

Audio Cubes II still shows the P-1 as being available. (?)

Audio Cubes has the non-American version. That's why. :)

Actually, I don't even know if that version will continue to be in production either... Hmmm...

Quite right. Euphonic it is, but to me it actually isn't euphonic it's annoying :) The P1 is not tubey it fast and details there is just something that I generally describe as "fun" about it that is not present in the GS-X, reminds me a bit of the R10s.

I'm not into headphone setups for that "fun" sound I want exactness more but that's me.

Well said.

The option I like is to have a fairly neutral amp (β22) and source, and then if I want a euphonic flavor now and then, that can be accomplished with a euphonic headphone. The modded Orthodynamics fit the bill there for me, and there are times when I do like that flavor.

Though I've yet to hear the combination, I assume that the β22/K1000 combo will be quite neutral for most of my listening tastes.

has anyone done this successfully? I've been very tempted to pick up a imported P1.

I forgot that I can test this now with the BelCanto Dac3. I'll have to do some testing with the balanced side of the P-1 to see if it sounds better.

Please advise on the balanced input test. Word on the street is the P-1 will be available again this year. I don't think the P-200 has even started shipping yet. The thing that is killing me is that AQII price for a P-1 is same as USA price for a P-200. The P-1 sure looks a lot more like a reference piece that than the P200.

AFAIK the U.S. P-200 is shipping, since I have one. :) But It's half the price of the P1 which I also heard through the grapevine would be ~$3000.
