แอมป์หลอด | Cary Audio - CAD-300SEI INTEGRATED AMPLIFIER | Single-Ended Class A - 15 watts

Since its launch, CARYCAD-300SEI has more than ten years of history. It is rated as the annual A-level product by the American fever book "Stereophile" every year. It can be said to be one of the most exemplary Cary products. Today, the Cary factory is constantly improving the CAD-300SEI to make it perfect. Just the 300B vacuum tube has also been replaced with a large brand (including CITRON, KR, WESTERN ELECTRIC ...) The power has also been increased from the original 11 watts × 2 to the current 15 watts × 2. The key to whether an amplifier is good or not is the circuit and important parts it uses (especially the winding of input and output transformers). CAD-300SEI uses the simplest and most direct single-ended amplifier circuit and the whole machine is used. Fever tonic parts (Kimber capacitor, Dala resistor, WBT socket ...), all connections in the machine are soldered by Kimber silver wire. The two output transformers placed behind the fuselage and shielded with an iron shell are specially designed by the factory. The air gap capacity is super large (twice than normal). It is wound with high-quality enameled wire and solid wax method, so its output Very efficient. The power supply filter uses two high-quality filter capacitors with a capacity of up to 1200MFD (this may be the secret of CAD-300SEI up to 15 watts × 2). In general, the amplifier only features the mid-frequency part of the sound, and the Cary CAD-300SEI is even in all mid-range and low-frequency bands (the sound is full, gorgeous, and gorgeous.

1. Use the single-ended amplifier circuit, the whole machine uses a variety of fever tonic parts (Kimber KAP capacitors, Dala resistors, SCR Sulun capacitors, etc.).

2. The output transformer is designed with a large air gap capacity (twice larger than normal), which is wound with high-quality enameled wire and solid wax method, so its output efficiency is as high as 15W * 2

3. Use bile duct: 6SN7 * 3 (front and drive), 300B * 2 (strong discharge)

4. Unique headphone output, headphone output or speaker output can be selected by switch

5. The American fever book "Stereophile" is highly praised, and has been awarded the annual A-level product for many consecutive years.
