IWISTAO HIFI Tube Preamplifier 12AX7B Tube Recterfier 6Z5P Classical M7 Circuit AC110V/220V Brown Wooden Edge
Model NO: WVTPA-M7
For audiophiles who started the tube preamplifier, those considered are mostly legendary newcomer three-piece set, i.e. M7, SRPP, Matisse. After comparing the three , it is no doubt that M7 will win a lot. A generation of legendary classic tube preamplifier - Marantz 7 (M7) ,its sound quality is known for its mellow, medium-frequency sweet and natural, and rich in vacuum tube flavor!
There is a rumor that M7 only has a good performance at intermediate frequency, which is actually wrong. After careful adjustment of the M7, its performance is very comprehensive, dynamic is also very good, human voice is natural and delicate, string music is smooth and stretched, positioning is excellent; and its high and low frequencies extendind is good, low frequency diving is deep and powerful, but also is not lack of elasticity.
The circuit of this tube preamplifie is derived from the classic M7 circuit and is modified and tuned according to the characteristics of modern devices (mainly coupling capacitors) and old capacitors.
