AOSIBAO M18 Tube Preamp Amplifier Mini Bluetooth Integrated Amplifier Rated 35W For Room Desktop

AOSIBAO M18 Tube Preamp Amplifier Mini Bluetooth Integrated Amplifier Rated 35W For Room Desktop

Advantages:
- Based on M 18, it supports about 30 kinds of tubes, including 6J2, 6K4, 6N15, 6H15N, 6BC5, EF40, EF95 and 6AG5
- Support PCI expansion interface, which can match different functional modules. Leading functions added
- Support NICAM technology
- The third generation multi-layer PCB patch circuit

Features:
- Compact audiophile tube amplifier
- PCI expansion interface for more functions. Electronic tubes can be adjusted through switches, so that the power amplifier is suitable for more electronic tubes. NICAM technology makes sound crystal clear
- Electron tubes are upgraded to 6N15. The third generation multi-layer PCB patch circuit. Integrated circuit layout optimization
- Fit nearly 30 kinds of electronic tubes. A special lifting circuit enhances the effect of tubes. Perform a second optimization on the original basis and launch the V2.0 version, adding a number of technologies. Some chips are polished and encrypted. Suitable for 6J2, 6K4N, 6N15 electronic tubes, etc.
- 6J6W for RAYTHEON is recommended to replace 6N15 series. The former's sound is thick and surging, human voice is full, moist and warm, delicate and round. And low-frequency power is sufficient
- Audiophile and high fidelity. Tailored for rooms and other small environment
- Selected components, including TDA7377 amplifier chip for ST, 4700uf power filter capacitors for NCC, Bluetooth 5.0 chip for JL, high-voltage capacitors for NHC, potentiometer for ALPS, capacitors for ELAX Rubycon, Blue audiophile capacitors and red coupling capacitors for WIMA
- Using high-performance 5.0 audiophile Bluetooth decoder chip AC6925A for JL
- TDA7377 chip for ST is matched with the tube preamplifier to create rich and sweet sound. TDA7377 is a 4-channel chip, bridged to 2 channels through engineer's technical improvement. The original 4-channel 10W has been increased to 2 channels with 35W maximum power, and the sound quality has also been improved
- Small and exquisite. One machine for dual use. Tube preamp can directly output to the power amplifier
- Support Bluetooth or audio line input to play. The direct output of preamp tube plays a paramount role in polishing and pre-amplification, rejuvenating ordinary power amplifiers or old power amplifiers. And its sound is sweet and warm, delicate and transparent
