The British Matisse Fantasy Line Stage preamplifier is the pinnacle of Matisse after years of research and development. Since its birth, the tube preamplifier has been famous for its outstanding design concept and pure and spotless transparent sound quality, and has become a reference for tube preamplifiers. This tube preamplifier uses the famous Matisse principle circuit. When laying out the board, it has made corresponding optimization adjustments again. It strictly follows the wiring principle of single-point grounding. A lot of thought has been put into the selection of circuit components. The circuit board uses imported audiophile components, and the power supply part uses the electronic voltage stabilization filter circuit used in high-end machines. It not only broadens the frequency response, but also has better low-frequency extension. The sound is round and delicate, and the tube flavor is very strong. You will never get tired of listening to it, and it can be popular with all people at a super low price. This circuit board fully takes into account the convenience of users. The input/output RCA terminals of the circuit board are directly soldered on the PCB with gold-plated sockets, the potentiometers are also directly soldered on the PCB, and even the power supply part directly adopts plug-in lock terminals, which can be directly plugged in, so that users can use it directly after receiving the circuit without complicated circuit welding. Different factory batches may have slight differences in appearance, but it will not affect the use Color: As Shown Material: ABS Package Contents: 1 x Classic Circuit Board Only the above package content, other products are not included.
