The E1 preamplifier is a pure Class A field effect tube amplifier. After fine tuning of parameters, the sound quality is very listenable, and the low frequency bounce is very sufficient and calm! This field tube Class A preamplifier is specially designed to match the E1 amplifier, and the impedance matching of the front and rear stages is very good.
800W imported Nippon Steel iron core pure copper toroidal transformer (specially customized small-volume toroidal transformer, the price is much higher than the conventional one, the volume is close to the conventional 600W-700W, it is a customized version, and the process and other aspects are required Higher than conventional technology); 60000uF Ina large capacitor filter, sufficient power supply to provide energy for the power amplifier; 3 pairs of Sanken 2SC2922/2SA1216 parallel output drive boxes for each channel, this tube has the reputation of being the king of tubes, and its driving force Powerful, the output current is very large! Recently, a customer reported to me: He heard from a friend who had a fever that the sound of the Sanken tube would be hard, but the E1 was soft and had no hard feeling at all. In fact, some audiophiles have a big misunderstanding about this. The direction of the sound is not determined by the tube. The circuit, parameters, debugging and tuning comprehensively determine the sound quality and timbre of the amplifier. For example: salt is salty, and there is salt in the food. Can you explain whether the food is salty or not?
The E1 rear stage is a differential field tube input. The input stage, I/V and amplification stage current have been calibrated and debugged for many times and then matched to the optimal combination. The sound is delicate and durable, and the dynamics are strong and flexible!
E1 merging machine parameters:
Frequency response: 5Hz-120KHz(+0/-2dB)
Input impedance/sensitivity: 47K/250mV
Signal-to-noise ratio: 99.6dB
Dimensions: 430 wide, 135 high, 360 mm deep (height 135 includes foot pads, depth 360 includes front knobs and rear binding posts)
Net weight: about 14 kg (28 catties), about 16 kg after packaging
Output power: 180W*2/8R; 300W*2/4R are rated continuous undistorted power
The E1 integrated machine adds a preamplifier output function, which can be connected to a pure power amplifier, making it more playable!
The sound field is wide, the sound is clear, and the control is excellent! The bass is deep, flexible and has strong driving force!
