Fully Balanced NFCA Headphone Amplifier
Topping - L70
(Black)

Ultra-High Performance NFCA modulesTopping's L70 uses the same NFCA (Nested Feedback Composite Amplifier) module as the A90, giving it that TOPPING “house sound”. This, along with UHGF (Ultra High Gain Feedback) technology, provides excellent DC and AC performance, ultra-low THD+N, and an absurdly high dynamic range of 146dB.
Fully balancedThe built-in fully balanced amplifier circuit performs exceptionally well with both balanced and single-ended headphones. Additionally, the L70 includes four jacks to accommodate most headphones: 4-pin XLR balanced, 4.4mm balanced, 6.35mm single-ended, and 3.5mm single-ended.
Ultimate compatibilityTopping designed the L70 to be able to power the vast majority of headphones. With high output voltage, it easily drives high impedance headphones. With high output current, it easily drives low impedance headphones. And with low output noise, it easily powers highly sensitive IEMs without creating background hiss.

Amazing Features
Say goodbye to ground loop noise
When multiple pieces of equipment are used in conjunction, ground loop noise can occur. Ground loop noise most often manifests as a buzzing or humming sound, which is capable of being loud enough to damage speakers. Although it's known to happen most often in single-ended feeds, it can happen in balanced feeds, too.
The L70 solves this issue with a GND/LIFT switch. When in normal use, set the switch to GND. If you encounter ground loop noise, set the switch to LIFT, which will change the ground point of the L70 from its chassis to the equipment it’s connected to, eliminating the noise.
2 gain settingsThe L70 has 2 gain settings, which cover a wide range of use cases from low-sensitivity full-sized headphones to high-sensitivity IEMs.
R2R volume controlThe L70 uses an R2R volume control composed of relays and resistor networks, bringing the advantages of precise control, longevity, and complete channel balance.
Doubles as a pre-amp With the L70 in pre-amp mode, connect a power amplifier to drive bookshelf, desktop, or floor speakers. With the included remote control, you can control it all from the comfort of your couch.
Volume memorizationThe L70 can memorize the volume and gain settings for 8 separate outputs. These settings can be customized to different headphones and other devices, vastly increasing its usability.
12V trigger interface The L70 comes with a 12V trigger on the back panel. This simple jack lets you create a network between any units that also feature a 12V trigger. When connected, it makes one product control the power of the other products in the system. When you turn on one unit, the rest of the system comes on automatically.

Sennheiser - HD 800 S

The new standard for critical listeningThe Sennheiser HD 800 S headphones bring together the care dedicated to a handcrafted instrument and the precision of modern manufacturing, the HD 800 S allows you to explore your entire music collection from the inside out. After launching its predecessor - the HD 800, Sennheiser gave themselves the challenge to completely disappear from the last link in the audio chain, with the aim of providing acoustics so immersive that your awareness dissolves into the creator’s perspective. Each and every component of the HD 800 S is world-class. The signature sound of the HD 800 S is possible not because of a single component, but through the combination of them all.

Setting The New Industry Standard

Ring Radiator transducerThe transducer leverages the main benefit of a large diaphragm transducer, which is air displacement without losing the rigidity that favourably impacts rest and response times. Instead of a single attachment on the outer circumference of the transducer, both outer and inner edges of the “ring” are secured to the drive unit. The voice coil excites the diaphragm, connected to the v-shaped groove found near the center of the ring. A feat in itself, the voice coil is 40mm and wound in-house to ensure the shape and consistency is held to the highest standard.

complete stabilityEvery transducer is manufactured, tested, and measured to the highest tolerance to ensure the most dependable performance out of the box. The steel mesh found in the baffle is also matched and integrated with consistency as a priority, as it adds to the ultra-low variance in the management of travelling sound waves. Each HD 800 S includes the frequency response plot unique to those perfectly matched transducers, sparing no resource to help you hear the most vital nuances from every section of your music collection.
Mesmerizing Soundstage

perfectly matched transducer systemsA result of several key features, the drivers are mounted at a precise angle, guiding the sound directly to the listener’s ears at their natural inflection point. Instead of hearing a sound that forms between your ears, you hear a vivid blend of frequencies and sensory-stimulating transients.
When combined, the vibration damping chassis, perfectly matched transducer systems and wide-open construction work in concert to provide the most impressive soundstage yet. This orientation rivals or exceeds loudspeaker setups costing exponentially more, especially when room acoustics are factored in. The HD 800 S gives you a personal concert hall on-demand, without disturbing the neighbours.
Advanced Sound Reproduction System

Incredible ExtensionGaining acoustics that are true to the source also requires management of compounding frequency clusters that produce undesirable masking effects. Sennheiser integrated a patented frequency absorber, which is a principle similar to that found in the breakthrough IE 800S, to reduce resonances that hide extraordinary musical details in plain sight.
The transducer system is also mounted in a vibration damping chassis using aerospace-grade materials. Together with the previously mentioned headband, the problematic energy peaks of lower frequencies are managed to display the purity your hi-fi setup is capable of.
An Ergonomic Treat

Ultra ComfortEvery contact point utilizes ultra-soft microfiber padding, while purpose-made composites reduce weight and unwanted pressure. Each earcup offers dual-axis articulation, as soon as you put them on the HD 800 S will instantly and seamlessly conform to your unique structure. The result is an incredible listening session that never stands in the way of your passion for hi-fidelity sound reproduction.
