As the “flagship” pre-amplifier from Musical Paradise valve amp line up, the MP-701 mk2 retails at a very reasonable price  of RM2,947.  But don’t look down on it, the performance is comparable with its rivals that cost 2-3 times more!

Besides the various options for tube rolling, coupling capacitors on MP-701 are also interchangeable. The combination Bennic and OHVL caps (default configuration) sounds pretty smooth and natural. However, if you prefer to get a bit more bass slam, treble expansion, clarity and separation, I strongly recommend replacing the OHVL with a pair of VCAP ODAM (oil damped advanced metalized) audio capacitors! 

No worries, this “Capacitors rolling” on MP-701 is as simple as “tube rolling”; after removing the upper case, you will see 1 pair of "Bennic" and 1 pair of "OHVL" capacitors screw locked on the circuit board. Just loosen the screws to replace the caps. 
Capacitor acts is a kind of “battery”, so kindly remember to wear gloves while rolling the caps if you don’t want to get shock.

MP-701 supports a variety of preamp tube types, including ECC88/6922, ECC82/12AU7, ECC99/12BH7, (12SN7 and 6SN7 with adapter), and so on. Basically, with the ECC82/12AU7, it sounds smoother, more mellow, while with the ECC88/6922 it sounds more solid, energetic and faster.

Uses a single tube rectifier which can be rolled among 6Z5P/6X5, 5R4/5U4G/5AR4, GZ33, GZ34, 274B and so on.
These tubes are a plenty in the valve market, try to mix and match to get your preference sound.

The stock tubes of MP-701 are 1 unit of Shuguang 6Z5P and 3 units of Beijing 6N11 (or Russian 6N1P). Their sound quality is “OK”—clean, neutral and balanced, worth every penny you paid for. However, do some rolling to discover the full potential of the MP-701.

Low distortion three stages amplification circuit with user changeable gain settings. No negative feedback.

The power supply is a 150W toroidal transformer that provides sufficient redundancy to support most critical current requirement. It is magnet shielded in the compartment underneath the motherboard.  

The chassis is built with aluminum alloy face plate and steel body. knobs, tube protection rings and buttons are made with solid aluminum alloy. The simplicity of front panel design allows you get used to it in minutes.
