iBasso AMP7 3.5mm Module for DX220, DX200, and DX150

iBasso AMP7 3.5mm Single Ended Discrete Amp

Features

AMP7 is a complete new discrete circuit design that based on our four channel architecture and features both a high voltage and current output. High current output is very useful for low impedance multi drivers in-ear monitors.

Low VCE transistors are utilized and are manually sorted and paired, providing better consistency and linearity. The low VCE also expands the linearity range.

+/-8V high voltage swing. This significantly improves dynamics and headroom, resulting in a more accurate sound that is true to the recording.

The transistors used on the buffer stage have a up to 2700mA output current rating, which allows the AMP7 to drive IEMs and headphones that require high current with ease.
