MI7, released Germany KS digital coaxial active monitoring "C8-Coax/C5-Coax"

Both C8/C5, 2-way active near field monitor that placed low / mid and tweeter on the same axis.
 A coaxial driver, which was developed in the same series, adopted.

C8-Coax


C5-Coax




Since there is no deviation of the axis to the horizontal and vertical direction,
to achieve optimal pulse, frequency, and phase characteristics in the listening point
enabling a space-saving installation 
by such compact designs as size of 240mm for C8 top and bottom, 
left and right, and of 220mm for C5 top and bottom,
 left and right by the coaxial layout with 2-way.

Tanzan Akira previewed headphone amplifier of the Fire Stone Audio "Fireye Series"

Fireye HD 

In the finest model of "Fireye" series, 
smartphone size headphone amplifier classified in relatively large grade.

HD(High Difinition) named comes from emphasizing 
the basic function such as analog input and headphone output, 
and having the confidence in particular to the quality of sound. 

Charging battery, Lithium-ion battery that allows for 8 hours continuous drive, 
mounted with input gain switching circuit and bass boost circuit.



Alpha


Fireye DA

Headphone amplifier with built-in USB DAC 
at a size of about half of "FireyeHD", but also suitable to carry. 

Power supply, compatible with USB bus power. 

Characterized by such a multi-function that in addition 
to USBDAC headphone amplifier 24bit/96kHz, 
supports a mini-jack line output of 3.5mm, 
can also be used as a DA converter, 
and can also be used as DDC with S / PDIF (optical terminal output).




Fireye HA


Headphone amplifier, cheap model at a size of about half of the best grade "FireyeHD". 

Equipped with lithium-ion battery that allows 12 hours continuous driving 
and input gain switching circuit and a bus boost circuit,
 while limiting the thickness to 16 mm. 

In the own analog circuit, in pursuit of sound quality, 
incorporated with a function to limit POP noise when generated in ON / OFF, 
and function to switch the input gain(High / Low).

Denon, "DCD-1650RE", SACD player that supports hi-res music playback with USB-DAC

This unit is the successor model of SACD player, "DCD-1650SE"  that released in 2009.
Since 1650 series appearances in 2000, it becomes "the ninth generation" model.



"Advanced ALPHA Processing" technology,
 realized the high-bit and high sampling by proprietary data complement algorithm. 
Improved significantly the amount of information on the time axis by the high-speed signal detection and processing techniques.


By performing up-convert process 16 fold by this technology,
 without losing the texture of the original data, 
high-frequency signal with a frequency of 20kHz or more that was cut by sampling 44.1kHz, such as CD, also significantly increases the amount of information,
 precisely to a high frequency to realize the natural interpolation. 

Further, switching to optimum filter characteristics to match the waveform of the signal to reproduce the digital filter,
 "adaptive digital filter" is adopted to achieve a more natural signal reproduction. 


In Drive, adopted "SVH (Suppress Vibration Hibrid) mechanism" 
loader of hybrid structure that combines the Denon original, different materials. 

To suppress vibration when disk is rotated at high speed ,
 disposed the drive motor close to turntable. 
To design very short length of the motor shaft 
and to adopt a brushless motor with high life to be unaffected by high-speed rotation.



For vibration-proof structure of the whole, adopted "Direct Mechanical Ground" structure. 
To mechanical case made of iron to prevent resonance, 
the vibration-proof structure 3 layer bottom plate, two layers of top plate, to ensure high rigidity. 

Side panels in two-layer structure, 
thereby suppressing the resonance by the combination of different materials. 
Tray, aluminum die-cast. In drive mechanism, 
laid the center of gravity by mounting the center of the body
 to optimize the weight balance of the entire equipment.

Denon, pre-main Amplifier "PMA-2000RE" with "Advanced UHC-MOS single push-pull circuit"


It is characterized that is equipped with the newly developed amplifying element as
 "Advanced UHC-MOS single push-pull circuit" which has been evolved from
 "UHC (Ultra High Current)-MOS single push-pull circuit"
 While being a single push-pull circuit, 
adopted the circuit configuration of the ideal of high-power amplifier holding a strength comparable to that of about 35 of MOS-FET and 3 of bipolar transistors.
