KingRex Headquarters Headphone Amplifier
Eden
Audio would very proudly like to present to you the superb new hadphone
amplifier the HQ-1 from KingRex
The HEADQUARTER (HQ-1) headphone amp set is furnished with two chassis designs: piano glass paint steel complemented with red anodized, hair-brushed aluminum front panel for trendsetting style, and sandy-blast paint steel with black anodized, hair-brushed aluminum front panel for the timeless chassis look(18X45X55mm).
KingRex new – HEADQUARTERS
(HQ-1) is in Class A MOSFET design is general-purpose desktop headphone
amplifier.
HQ-1 has one input and two outputs which is selectable by front panel
push button- one is line-output and another is phone-output.
Gold-plated NEUTRIK 6.35mm headphone jack and gold-plated RCA terminals
for provide great contact.
The interior circuitry consists by first stage transistor –Toshiba
A970/C2240 for first stage amplification and output stage by Hitachi
MOSFET 2SK214.
Featuring Hi Fi grade Panasonic FM capacitor as main filter brings
the transparent background and balanced soundstage ; input capacitor
choose WIMA increase acoustic density; output capacitor choose Vishay
for more neutral and delicate details. All material choose for neutral,
balance, details, rich musicality, and vivid tuning.
Original ALPS potentiometer for provide the best signal for sonic
purity.
Input/ output signal path setting use FURUKAWA PCOCC which brings
more expansive and warm sound.
Discreet external linear power design- highly current supplied toroidal
transformer, LMS1585 constant voltage regulator, total 8pcs Hi-Fi
grade Nippon Chemi-Con Electrolytic capacitor in total capacity 25100uF(5
x 2,200 uF at AC input stage; 3 x 4,700uF at DC output stage) through
NEUTRIK XLR socket all design stream out fully power to fit active
dynamic demands.
Two style chassis design : Chassis design by piano glass paint steel
180 x 138 x 45mm with aluminum red anodized panel in hair polishing
The power supply is of the linear kind and runs off a 48VA toroid, with five 2.200uF caps filtering incoming AC, three 4.700uF units smoothing outgoing DC. Eight "hifi-grade Nippon Chemicon electrolytics" create a total power supply capacitance of 25.100uF. Naturally, output power varies with headphone impedance so we get 100mW at 300 ohms, 170mw at 150 ohms, 360mW at 60 ohms and 570mW at 30 ohms. At 2Vrms output, THD+N is 0.005%. Dynamic range is 110dB, channel separation >92dB at 1kHz and >76dB at 10kHz and S/N ratio 115dB
Dimension are 183 x 145 x 55mm for each unit and dress code is a black body with black or red fascia. Headphones used during R&D were Sennheiser HD600s, Audio-Technica ATH-AD700s, AKG 501s and Goldring DR150s.
KingRex say - "Basically we tuned the sound with the HD600s as we think them very neutral and balanced. We tried many different impedance headphones to assure the amp performed well regardless of load."
We invite you to listen to all the Kingrex range at eden audio, we think you'll love what you hear. Kingrex products offers superb sound performance at mouth watering prices. The beauty of them is there small size, you can fit them almost anywhere because they wont over take your room due to its compact size. Enjoy your music with Kingrex.
