Musical Paradise MP-701 MK3 Tube Preamp Best Upgraded Remote Edition Preamplifier AC100V-AC240V

On May 5, 2024, MP-701 MK3 is officially released. Upgraded the filtering inductor on the basis of MK2 and added a filament stabilization circuit. The background is darker and the sound quality is higher.


Technical highlights:
1. The onboard filament voltage switch can support 6.3V and 5V rectifier tubes, as well as 6.3V and 12.6V signal tubes.
2. On board DIP output gain adjustment switch, users can choose four different levels of output gain to support downstream devices with different input sensitivities. 3. The zero negative feedback circuit provides the most natural sound.
4. The oversized 150W ring transformer can provide sufficient redundant electrical flow. It is placed in the electromagnetic shielding compartment under the motherboard.
5. Quick installation capacitor design allows users to freely replace output coupling capacitors and power filtering bypass capacitors to further improve or customize different characteristics of sound, without the need for welding and easy replacement.
6. The entire machine adopts original genuine HiFi grade components, such as Vishay military grade resistors, Rybycon and Nichicon low ESR power filter capacitors, Obbligato Gold coupling capacitors, Bennic XPP power bypass capacitors, ALPS volume control and power switches, and genuine gold-plated terminals.
7. All aluminum alloy chassis, solid aluminum alloy shock absorber cone feet and button knobs.
8. Equipped with remote volume control function.
