With a gold-plated stereo RCA stereo input and output, it will be a quality companion coupled with a class D power amplifier to restore dynamics and sound to any missing installation.

At the price offered, this device has qualities usually absent in this category.

Moreover, this preamplifier does not have the caricatured sound impastoed in the lower midrange of classical tube productions. On the contrary, the terms transparency, dynamics, musical unbridledness, sound matter are the ones that immediately come to mind.

An entry level excellence for any enthusiast who wants an affordable tube preamplifier of high quality.

NOTICE: This amplifier is a Pre-Amplifier. This means that it needs to be connected to a separate power amplifier before it can be used. It can match digital power amplifier, analog power amplifier, active speakers. Since it is not a Phono preamp, it is not suitable for turntable. The RCA cable is not included.
