• 【Exquisite Design Premium Craftsmanship】 Ultilizes an advanced microprocessor controlled relay-based 60-step attenuator
• 【Product panel display】 Good materials are essential for good sound quality. Finding the ideal balance between size and sound quality saves space without compromising on sound quality.
• 【Pure copper toroidal transformer outputs more powerful power】 Chopin power source is a high-power 65W toroidal transformer combined with a large number of American ERSE capacitors, providing stable power supply for the entire machine, forming 8 independent regulated power supplies
• 【Rich interfaces】 The conversion rate of a fully balanced output circuit is approximately twice that of a standard circuit, with significantly better noise rejection capabilities.The differential amplification circuit uses imported ON Semiconductor field-effect transistors for output amplification
