SMSL after sales service return product. New product, box slightly damaged.
Here is the brand new SMSL SAP-9, a headphone amplifier at symmetrical output which is the culmination of a long search of the brand's engineers. 2 amplification chips TPA6120A2 were used, so the amplification circuit separates the 2 right and left channels well.
In order to create a balanced circuit with zero noise and an extremely clean sound, the latter has a completely independent architecture and tracking. The volume control of this headphone amplifier will be done in the best digital way.
The SAP-9 SMSL offers you a connectors extended. In analog inputs, you will have the balanced stereo XLR port as well as the gold-plated stereo RCA port. In analog outputs you will have a 6.35mm jack headphone jack, a 2.5mm 4-pole balanced jack, as well as to complete the 4-pole balanced XLR headphone output her too.
