Description

Shinobu Karaki-san's brand new hybrid is out - the HFSA-01 Integrated Amplifier, utilizing EL84 valves with an output of 14 Watts per channel

"Hello, I'm Gerardo Ventura. There's nothing quite like it. At these levels (price and output power), there's nothing as musical. I would listen to it day and night. Perfect for Living Voice, excellent for any LS3/5a, and many, many other speakers. It's not just 14 Watts per channel. It's completely magical."

HFSA-01 is a hybrid pre-main amplifier utilizing the advantages of both vacuum tube and semiconductor. The tube EL84 delivers 14W + 14W power output. The model is equipped with bass and treble controls. The input stage has a built-in phono equalizer for MM-type cartridges, along with 3-channels of RCA unbalanced input terminals.

This model accepts speakers with 4-6 Ω to 8 Ω impedance. In addition, it has a headphone output.

HFSA-01 is designed with orthodox configuration, however, it fulfills the basic requirements such as sound quality and overall performance for a wide range source from high-resolution digital to analogue records that any generation and age demands. 

The retrò style front panel ornamented with Mahogany wood on both sides to enhance the retro appearance producing a rather relaxing atmosphere for more enjoyable audio life. 

Il pannello frontale di ispirazione retrò contiene due manopole che possono essere sostituite con manopole in legno di mogano (opzionale) per esaltare ulteriormente l'estetica vintage e produrre una atmosfera rilassante.   

Feature 

The output vacuum tube EL84, a pentode equivalent to 6BQ5, is operated in push- pull configuration delivering extremely low distortion and excellent frequency characteristics with ultra- linear connections. The driver for EL84 is a well- known Texas Instruments OPA604A, a high precision audio Op-Amp. Aurorasound developed a perfect phase inverter circuit with OPA604A to drive the push-pull operation in the most ideal way. 

Editor's note. Dear music enthusiast, if you're used to turn up your nose regarding the use of Op-Amp devices, with Aurorasound you may sleep soundly: as well as in the ultra-talented VIDA Prima Phono Preamp, the use of Op-Amp chips does not produce any apparent downside; the result is not only balanced and natural but also throbbing, full of sensations, dynamic and subtle details, with emotion and atmosphere.

The tone-control section employs a CR-type for easy adjustments to achieve more rich bass and comfortable treble to meet listeners’ sound taste even with small-size speakers. 

NOTE: You will find free of charge included with the amplifier the optional front plate that allows to set the typical equalization curves suitable for the different types of vinyl recordings and not only: 78rpm records, DECCA, Lp-Columbia, AES and NAB. Also the CD digital signal may be compensated to obtain the perfect timbre balance (you may find the front plate in the image section).

The phono equalizer uses Linear Technology’s semiconductor to achieve an excellent S/N characteristic with NF-type circuit configuration. 

The power supply section is completely isolated between the vacuum tube and semiconductor to completely eliminating any interferences regardless of volume level and frequency range. The rectifier is of the super low noise Rohm’s silicon carbide diode. 

The output transformer and power supply transformer are custom designed by Aurorasound, and manufactured by a Japanese company. This model employs carefully selected high-quality capacitors and resisters, as well.
