Description
TUBE AMPLIFIER HOLY GRAIL
The HA300 MK2 is a Class A, single-ended triode vacuum tube headphone and speaker amplifier that pushes the envelope of tube amplification when it comes to practicality, performance, and refinement.
The Pursuit of the Direct Heated Triode (DHT)
Directly heated triode (DHT) is the tube amplifier’s holy grail. DHT refers to triode tubes that use the cathode as the filament to heat the cathode directly. This minimalistic approach offers stellar dynamics and transients.
The Irresistible 300B
300B is the most renowned and sought-after DHT because of its dreamy tonal characteristics. The HA-300MK2 uses a matched pair of Gold Lion Genelex PX300B low-noise audio triodes as power output tubes. These tubes deliver a natural and realistic sound with impressive frequency extension.
Beautiful and Durable Design
The HA-300MK2 features a brushed aluminium-magnesium alloy front panel, which provides strength and corrosion resistance. The panel is black anodized for added durability and scratch protection. The chassis and transformer pots are treated by Cayin’s proprietary 14-round crafting process composed of scratch, spray, sanding, and baking. The high gross final finishing endows a refined and delicate texture while protecting the amplifier from years of long service.
Less Is More: A Simple Circuit Design
Single-ended triode (SET) amplifiers use a single triode vacuum tube to produce amplification without splitting the music signal into parts. A pair of driver tubes amplifies the signal voltage so that the 300B output tube will linearly perform its amplification.Â
Cayin has developed many 300B-based SET amplifiers, and 6SN7 is always the first choice for a driver tube. The HA-300MK2 uses a matched pair of Tung-Sol 6SN7GTB tubes to complete the two-stage SET amplification.
TUBE REGULATED POWER SUPPLY
2-Box Design
The HA300MK2 uses a two-box design. The outboard power supply minimizes the ripple effect and offers clean, low-noise power to the amplification circuit. The multi-tube regulated power supply circuit feeds power to different amplification stages independently.
Power Supply Transformer
The outboard power supply is driven by a high-inductance, high-efficiency toroidal power transformer, which Cayin designs and winds in-house.
New Old Stock (NOS) Rectifier Tubes
The HA-300MK2 uses 4x NOS 22DE4 tubes from RCA, one of the best versions of 22DE4 available in the tube market. Unlike output tubes, rectifier tubes don’t involve heavy lifting loads and can last very long without deteriorating. Plus, there is no matching requirement; they can be replaced on a per-piece basis.
TRANSFORMER-COUPLED DESIGN
The 300B SET output drives a pair of proprietary output transformers, supporting both headphones and speakers. The secondary winding of the output transformers provides an alternative phase and composes a balanced output, enabling balanced driving from a SET amplification circuit. Both single-ended and balanced headphone outputs are “original” outputs from the transformers. With a pair of EL Transformers, the HA-300MK2 delivers a natural and realistic sound across the frequency range.
With a pair of EI Transformers, HA-300MK2 delivers a natural and realistic sound across the frequency range. Cayin designs and winds the all transformers in-house.
ENHANCE YOUR DAILY USAGE
Combinations all audiophiles will cherish and admire: purity of single-ended triode amplifier, the dreamy sound signature of 300B, and authoritative dynamic and control when called for. With up to 6w per channel, provides all the power you need to handle a vast selection of headphones, from portable friendly dynamics to extremely demanding players.
Custom-made silica gel shock absorbers between critical tube components, the chassis mainframe, and tube sockets effectively remove microphonics. Reinforced shielding of transformers and effective circuit layout minimize interference. Finally, a 60-second startup delay circuit enhances circuit protection and minimizes pop noise during startup.
The HA300 MK2 features lock-on & quick-release aviation-grade copper connectors. A silver-plated Teflon umbilical cable connects between outboard power supply and amplifier circuit.
