SUGDEN CD-21SE CD turntable, the overall appearance of the momentum is even more extraordinary, the panel only sees the control buttons and power switch for playing CDs, the operation function is very simple, and it has the design taste of advanced models.
The internal circuit planning of this equipment is simple and neat, and high-quality audio-grade components are selected. Starting from the power supply, the system uses high-quality toroidal transformers with excellent characteristics of low magnetic leakage and high current, and is planned Multiple sets of voltage stabilizing circuits effectively improve the stability of the power supply.
As early as 1960, the former Research Electronics company of "Surton" had been established by Jim·Edward·Founded by JimEdward Sugden. Thurton was originally an engineer at EMI and Granda TV in the UK, and he is extremely well-known in the electro-acoustic industry. Since Thurton was the chief rudder of Research Electronics, the company''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s products were developed and produced under his leadership, and the company later simply named it "Thurton".
In the 1960s, audio manufacturers launched Class B amplifiers one after another to save costs. "Surton" still stood out from the crowd and insisted on launching high-cost but sweet-sounding Class A amplifiers. The amplifier introduced by "Surton" is well-known for its beautiful sound, reliability and durability. Take this A21SE pure Class A combined amplifier with 30W output per channel as an example. Her predecessor, the A21, has been out as early as 1969. The age of the aircraft is incredible! This amplifier may be the longest-lived model in the world so far.
