Two Nichicon KA 25V 6800uF electrolytic capacitors and WIMA Film MKP2 0.1uF.
The limited edition M2N uses three Nichicon PLG solid polymer capacitors 16V 470uF, making it a high-performance version limited to 16V withstand voltage.
Total electrolytic capacitance 15010uF
- 12V~15V switching AC adaptor
- 5V~12V transformer AC adaptor
- 5V~15V linear power supply
- USB PD GaN 65W or higher adapter + USB trigger cable
FiiO K7 confirmed to work with the genuine switching AC adaptor of an authorised FiiO K7 import.
Note:We have confirmed that the Petit Tank Limited Editon can be added and works properly, but it may spoil the performance of the x2x series.
Please use at your own discretion.
It reproduces reverberations, fine fluctuations, etc., while having noise reduction and fast response in all ranges.
The K7/K7BT has noticeably higher sound quality in the high frequencies, including clear high frequencies and tight low frequencies, improved over the standard version, and in the high-resolution range.
In addition, every single sound in the mid-range is reproduced.
Singatron 2DC-G213-D42
5.5 mm OD / 2.1 mm ID
DC jack manufactured by Singatron, Taiwan.
Metal body and robust settings for secure connection.
Murata EMIFIL BNX016-01
Combines conventional common/normal mode coil/capacitor in one,
Reduces noise by 40 dB over a wide bandwidth from 100KHz to 1GHz, which is unreachable with conventional products.
Nichicon PLG 16V 470uF x 3 (1,410uF)
Nichicon's ultra-low ESR solid polymer capacitors
The 2N series uses three Nichicon PLG solid polymer capacitors, which are more expensive but provide even better noise suppression than the standard version.
Nichicon PLGs are limited to 16V because they are only released up to 16V withstand voltage, but they provide powerful noise suppression with a low ESR performance of 11 mΩ.
WIMA MKP2 0.1uF ⅹ２
Film capacitors made by WIMA of Germany, which are also used in professional audio equipment.
Together with Nichicon UKA, they are responsible for noise reduction in the audible to high-resolution range.
Due to its high performance, Nichicon UKA can sometimes oscillate, so the high sound quality is maintained by using WIMA film in combination.
The limited edition 2x series uses two MKP2s, which are more compatible but more prone to oscillation and are more expensive, to suppress oscillation and achieve clearer high frequencies and tighter bass frequencies than the standard version.
Nichicon UKA 25V/6,800uF x 2 (13,600uF)
Nichicon's current top-of-the-range audio grade capacitors.
105°C-compatible, high-grade product with carefully selected components for improved sound quality.
It reproduces a straightforward sound from the bass range to the high frequencies, including the high-resolution range, without any lingering sound.
The BRi-PSM01-M2N achieves even better sound quality in combination with the MKP2 and uses a 6,800uF KA to compensate for the lower smoothing capacitance due to the addition of solid polymer capacitors.
Instead of limiting it to 12V or higher switching/5V or higher transformer/USB PD 65W or higher adaptor, an additional total of 13,600F is additionally loaded for further noise reduction and power smoothing.
The system has been adjusted so that the switching limit due to the increased smoothing capacity does not occur when the Petit Tank Limited Edition is connected.
