OFFICIAL REVIEW (2021): MEET THE ATC-5

“Compact as it is in size, the ATC-5 admits of no compromise in design and components selection not to speak of manufacturing in total. Bearing a common resemblance to its predecessor A TC-1 in design concept, we poured into a tiny body all of our 30-year accumulated technologies and know-how in terms of pre-amps’ presentation, while putting globally-selected capacitors and components into a mere 1.6mm-thick chassis featuring monocoque structure, we keep sticking to our famed, traditional manual wiring by our expert technicians, totally abandoning cost-saving printed circuit’s. On the volume control sector crucial to overall sonic quality, featured on board is the Alps gold-plated multi-contact wire-brushed controller sealed in a machined brass case. Needless to say, all the Air Tight audio gear is designed and made in Japan.

To ensure perfect playback of analog discs, we employed a highly rated 2-stage NF-CR circuitry for the most faithful realization of RIAA curve. The NF and CR sections are made independent with a thorough elimination of interference between treble and bass ranges, and unnecessary low-frequency signals are crossed out to prevent unwanted vibration of speaker cones. Also provided is a useful muting function when vinyl discs are replaced in the course of playback. Abundant 3-line input allows listeners to enjoy multiple digital sources. A timer-relay system mutes output at the outset of playback, thus protecting the power amp section from the transient current. The line amp section consists of orthodox 2-stage configuration featuring the 12A T7. For the sake of tight and spacious soundstage, placed are optimum decoupling circuits at all the necessary points to prevent harmful interferences.

The ATC-5 is a high-resolution preamp that even represents the sense of ambiances and emotions at the time of recording, and the reality of reproduced sound with its second-to-none spatial reproducibility outstrips those of its all predecessors.

Air Tight, we have been keeping on manufacturing tube amps since the very inception, believing in the unlimited potential of Vacuum Tubes which were once thought to be out of date in contemporary digital days.

It was 30 years ago when we introduced the first tube pre-amp ATC-1 at Air Tight with the firm intention to reproduce real, dynamic sound, and thanks to our unyielding zeal and efforts we have been successful in winning the constant fame and reputation in the industry. After the years’ strenuous research & development we are now proud to present you the totally redesigned, mighty descendant ATC-5 to cater for the serious demand for real music sources, whether analog or digital.

To simplify the signal path in audio circuitry has been an influential idea since digital music sources represented by CD got rapidly widespread, but does such simplification really enrich the scope of music reproduction? We believe the development of control amp depends on a never-ending process to find the optimum balance between the technology and art itself. A technology to process properly in both analog and digital ways is not always in alignment with that of creating joy, emotions, excitements, and artistry of music. Air Tight believe that the ultimate optimized combination of the technology and art shall eventually create a sort of supernatural phenomenon in the form of real musical sensation. This is our uttermost goal and sublime dream commonly owned by all the discerning audiophiles in the world."

Operational:

Our industry might have evolved over the years, but there is no confusion of the preamplifier key task. With the drifting from analog-to-digital and with an ongoing resurgence of turntables/tape machines back towards the analog, any preamplifier needs to treat both of the "contrary" worlds with equal attention.

ATC-5 Valves employs three 12AX7 (phono equalizer) and two 12AT7 (line stage), two phono MM inputs, three line inputs, one phono output and two line outputs. On the front panel, appearing from left there is phono input selector, balance knob, main input selector, operate (mute) switch and on the far right the main on/off knob.

There are a plenty of electronic parts to inspire under the “hood” and I’m sure many of you have already identified the upper echelon ALPS brass potentiometer. ALPS RK series are well established and accepted by some of the most exotic high-end audio brands. Air Tight ATC-5 uses a custom version of the RK-501. Any DIY enthusiasts or well-informed high-ender know, how these don't come cheap. The basic ALPS RK-501 potentiometer costs almost 500 EUR. Surely wish I would encounter more of such premium parts across some exuberantly priced preamplifiers out there.
