That's a bit disappointing. It doesn't seem like a big upgrade over the P-1 if it can be called an upgrade at all.

I guess Luxman America's going to sell it for $3000, more because of where the yen is in relation to the dollar today than because of improvements made to the design.

For reference, these are the P-1 mkI specs

Continuous Rated Output

4W+4W/8Ω and 2W+2W/16Ω,

1W+1W/32Ω and 500mW+500mW/64Ω,

53mW+53mW/600Ω

Input Sensitivity / Impedance

1.0V/23KΩ balance 1.0V/66K

Total Harmonic Distortion

0.008% or less (1kHz), 0.025% or less (20~20kHz)

Frequency Response

20~20Hz (+0, - 0.1dB), 10~100kHz (+0, - 0.5dB)

Signal-To-Noise Ratio (IHF-A)

Above 108dB

Inputs

One pair of RCA sockets,

One pair of Balanced sockets on XLR.

Outputs

3 outlets - quarter inch standard headphone jacks

Attachments

Volume, Balance controls, Balance Control Bypass Switch, Input selector switch,

Power switch, power source on (protection) indicator,

Balanced & UnBalanced Inputs, Line Phase Sensor, AC inlet

Electric Power Consumption

31W

Dimensions W x H x D

16.4"(467)

I posted this on HF, but if one turns up at the local Stax dealer (small hi-fi shop) then I'll see if they wont let me take internal shots, though some will surely turn up on a Japanese blog somewhere sooner or later.

I got a email from on a higher note yesterday with the following information

"Luxman are replacing the P-1 reference headphone amplifier with the P-1u; another class A design, the P-1u features ODNF 3.0 and is more than four times quieter than its predecessor. We are expecting our first shipment of the P-1u in September @ $3,000; these are expected to sell out quickly as initial supplies will be limited."

Getting pretty expensive there. Wonder will the pricing on the original P1 will drop to 2k.

4x quieter? I don't hear any noise in mine at all. What is 4x zero...

Hmmm, maybe I should try it in the middle of the night, when it is dead quiet, to see if i hear anything. Not that I'd sell it anyway. I like my P-1.

P1u... I guess the "u" means ultimate in this case, going by the claims of performance.
