New York City, NY, February 16, 2018 Leading audio manufacturer Zhuhai Spark Electronic Equipment Co., Ltd., marketing their Hi-Fi products under the name of Cayin, will introduce their latest Single End Triode (S.E.T.) Class A tube amplifier, HA-300, at CanJam NYC 2018, Uris Room, New York Marriott Marquis, New York City, from 17th to 18th February 2018.


Bin Liang, CEO of Zhuhai Spark Electronic Equipment Co., Ltd., parent company of Cayin, said “This has been one of our longest and most intense projects in the last decade. We spent 450 days in R&D before the HA-300 was production ready. We underwent three major rounds of re-design and 17 rounds of optimization and refinements prototyping. The HA-300 is developed around the 300B Triode Vacuum tube, aka the Dream Tube of audiophiles and tube enthusiasts. We have selected 6SN7 to pair with 300B for a push-pull signal amplification. This is a very familiar Class A single-ended amplification design that Cayin has extensive experience with in past 20 years. Yet, we have not taken it for granted and did our very best to develop a statement headphone amplifier that we are proud off.”


Design Philosophy


The HA-300 adopts the two stages single-end Class A amplification with balanced output design. The output of the 300B power tube will feed to a pair of output transformers for single-end or balanced output. Being one of the biggest tube amplifier manufacturers in the world, Cayin designs and builds our transformers, making sure even the finest detail will be attended to. In the case of HA-300, the output transformer was specially winded to provide three set of impedance matched outputs at 8-64Ω, 65-250Ω, and 251-600Ω respectively, making it extremely versatile to match with a wide range of headphones in the market.


We also built an outboard power supply for HA-300. On top of the in-house design, custom-build toroidal power transformer, we developed a special circuit to supply steady power independently to different gain stages. The voltage amplifier circuit will adopt an independent regulator design, and we shall deploy 4 pieces of NOS RCA 22DE4 as rectifier tubes. This power supply design will deliver the cleanest power possible with minimal interference to the line signal amplification in the main Amplifier chassis.

      On top of a 6.35mm singled-ended and 4-pin XLR balanced headphone output, the HA-300 has a set of speaker outputs so it can be used as a speaker amplifier delivering up to 8wpc Class A output.




Pricing and Availability

The new tube amplifier is planned to launch in March 2018. The suggested retail price is US$3999.


The HA-300 will be demonstrated at CanJam NYC from the 17th to the 18th February 2018.  Cayin will also display their complete line of Personal Audio products including the latest Android based Digital Audio Player N5ii and the completed i-Series three-piece desktop suit at this CanJam. Please visit us at the Uris room or contact Mr. Andy Kong to reserve a special press audition session.
