It looks like a very well built SS headphone amp, the cost is 220000 yen, around 1700$...
Look! Glasstone HPA-20 inside!

Yeah, is that a 1:1 sized picture?

Proved that despite its huge size the CD3000 can be shoved down one's throat.

Please, look dimension and weight of the amp...
GLASSTONE HPA-20 Headphone amplifier:
The amplification circuit which the glass tone has pursued over four years and which is proud of the operating characteristic of an ideal "a blue circuit."
As the first cartridge, it is the highest peak of headphone amplifier. "HPA-20" It ‚ª’a?¶(ed).
It is the orthodox highly efficient amplifier which realized powerful drive capability for it to be developed based on the idea "power amplifier and basic structure do not change head phone amplifier, either", and to have sounded the headphone with inside with much head phone amplifier finished in the simple circuit compared with power amplifier.
the former and a thing -- it is equal to a capacitor type about the dynamic type headphone said not to suit a capacitor type about resolution -- high -- it has sounded with the tone quality of a high level which reconciles resolution and dynamic type forcibleness and which is not once
"HPA-20" It is not an overstatement although the limit of ‚Í and a dynamic type headphone will be made to be exceeded. Please experience the shocking sound with your own ear by all means.
The "blue circuit" which realized circuit composition ideal from the “®“Á?« of each semiconductor to the balance of the whole circuit is adopted. The know-how cultivated by business-use special order apparatus is introduced.
The high bias current design sharply exceeding the point operating [ Class A ]. The stability of the operating characteristic of the output stage corresponds also to increase and the sharp signal of a standup in a margin.
The powerful power supply circuit which adopted the TOROI dull transformer with electric power 10 times [ no less than ] the capacity of required.
The highly efficient article which used the golden tension silver alloy point of contact is adopted as the relay for Mu rocket TINGU (for protection).
The main specifications :
- The Class A operation maximum output: 0.8W (64ohms), maximum output 2W (64ohms)
(The maximum output changes with impedance of a headphone)
- Frequency band: DC-100kHz
- Rate of distortion: 0.001% (1kHz), remains noise:10uV (JIS-A)
- Power consumption: 13W
- Size/weight: A width of 344mm, the depth of 355mm, and a height of 85mm (projection •”ŠÜ‚Ü‚¸) / 3.4kg
The catalog of PDF form From [ here ] It can download. Those who wish to have the catalog of paper, With an E-mail Please ask.The audition machine is lent out. Details Here Please give ‚ðŒä——. E-mail Please be alike and ask our company directly. A delivery charge is national no charge. By hope, I append the cable for XLR->RCA conversion / attenuation. Moreover, it is also possible to change the main part itself into XLR input specification.
Details With an E-mail Please ask.
