P7-MINI Preamplifier Board Top Pre-AMP Headphone Amp Kit
- This is a well made pre amp board, full DC，no coupling, simple, while sophisticated.
- Avoid any distortion caused by capacitors. And bandwidth limitations.
- Frequency to DC 1HZ, high to 1M HZ.
- Using double-sided gold-plated military grade PCB material.
- Previous level can be better with MX50, L20, L6 and other power amplifier boards.
- Cable can be easier ways to avoid the wrong signal line connections for a variety of noise problems.
- Not recommended after amplification with the use of DC power amp board.
