SUQIYA Goldmund G29M Pure Power Amplifier 350W*2 Class A and B Fever Hifi High-fidelity Split Amplifier Audio

G29M Introduction
1. Introduction to different versions (price is 1 pair): The standard version and the upgraded version are only different in filter capacitors, the other parts are the same, and the upgraded version has a more delicate sound.
Standard version: The large filter capacitor is Japan's ELNA
Upgraded version: The large filter capacitor is Nichicon Super Penetration
2. The circuit is an imitation of the Gao Wen 29M amplifier part. The field tube differential input ensures that the total harmonic distortion is minimized. After repeated audition and blind listening, the differential input current is determined to be 1.5MA; the subsequent amplification and current level are 4MA and 80MA. At this time, the human voice and string music are very outstanding, the three frequency bands are very balanced and extended very well, and the analytical power is extremely high! It can restore the authenticity of the sound source very well without any modification.
3. The sound is full and thick, and the low-frequency dive is also very good, which can reach 8Hz. It is very suitable for listening to piano instruments, the kind of soft and quiet lying on the sofa to listen to music quietly, the human voice, especially the sound of the sound, is very good, and it can bring people to sleep slowly. It is very calm and soft, and can restore the sound of the sound source very realistically. The dynamic range is very good, the bass is strong without losing "warmth". The low frequency can be freely controlled; the mid-frequency is full and thick! Playing piano music can make people "see" the sound of mountains and flowing water, the treble positioning is clear and natural, the saliva sound is very good, and you can feel that the music is not transmitted from the ears to the brain, but from the eyes. The wide sound field is a major feature! The imaging performance is very good.
