AIBBC HF-2050 Power Amplifier MOS Tube Stereo Power Amp 130W+130W Dual NS DIP-8 LM833N Op Amp

AIBBC HF-2050 Power Amplifier MOS Tube Stereo Power Amp 130W+130W Dual NS DIP-8 LM833N Op Amp

Description:
The standard version amplifier uses audiophile-level dual op amps, NS DIP-8 LM833N made in Malaysia for signal input and signal amplification. NS LM833N is a dedicated op amp designed for audio. You can see it on many HIFI-END level front boards. The operational amplifier has a wide sound field, excellent high and low frequencies, moderate thickness of the intermediate frequency, low distortion, low noise, high signal-to-noise ratio, and high bandwidth. It is widely used in high-quality audio circuits and other circuits that require first-class dynamic performance In the machine with high resolution and fine tone. The driving op amp uses two BB flagship op amps OPA627AU single op amp. OPA627 has extremely high resolution and excellent bass dynamics. The intermediate frequency is moist and smooth, the vocal is rich and delicate, the high and low frequency extension is very good, the resolution is high, and the vocal Friendly, gorgeous and transparent high frequency, pure and thick intermediate frequency, good low frequency dive and strength, and the sound field expands forward and backward.
