iBasso AMP5

iBasso AMP5 3.5mm High Voltage Swing Headphone Amplifier Card for ibasso DX200

Description

• +/-8v high voltage swing, this significantly improves dynamics and headroom, resulting in a more powerful sound.
• Topology utilizing voltage and current feedback, with the positive benefits of both types of feedback
• Optimized buffer architecture, results in a lower current consumption and higher play time, but still able to output a high current into the load.
• Topology utilizing an amplification circuit and component layout resulting in a clean and very fast transient response.
• The AMP5 offers the single ended user a high current and voltage amp for demanding headphones. It is also very quiet and works well with IEMS. With an extremely low background noise, music is all the more layered and transparent. AMP5 handles the dynamics of the music and delivers excellent headroom giving the quality of sound that so many hope for

iBasso AMP4s 4.4mm High Voltage Swing Balanced Amplifier Card for iBasso DX200/DX150

Description

• ±8V Voltage swing, equal to a 32V voltage swing on a single ended AMP. This significantly improves dynamic and headroom.
• Patented balanced amplification circuit, that retains all the benefits of a balanced design, such as higher output voltage and better separation while at the same time, our Patented design has even harmonics that keeps the sound full and musical.(With the traditional balanced amplification circuit design, there is a positive signal and a negative signal. They together reduce the harmonics. On this amplification design, even though sound is more powerful, the sound is flat and less musical, as even harmonics are reduced. On the iBasso balanced amplification design, we successfully reduce the odd harmonic, while retaining the even harmonics, thus keeping the sound full and as musical as single ended but with the added benefits of a balanced signal.)
• Topology utilizing voltage and current feedback, with the positive benefits of both types of feedback.
• OPAMP+BUF architecture, optimized for both high voltage and high current demanding monitors.
• Based on the AMP4, the AMP4s has a shortened point to point distance for some parts and a further optimized layout. The capacitor selection has also been changed to work with this new design.
• Benefits of the 4.4mm connector are larger contact points, which lower the contact resistance and enhance signal transmission.
• Compatible with iBasso DX200 & DX150
