Description

The HAS-GR amplification system is an all-hand-made boutique, designed for the most enthusiastic audiophiles who cannot settle for anything else but the absolute best.

The HAS-GR is not to be confused with a tube preamplifier driving two solid-state monoblocks. Every power amplifier has a voltage gain stage, in order to amplify the small signal coming from the preamplifier or any source, and a power current stage so it can drive the speakers. The HAS-GR Control Unit provides all the voltage gain using ECC99 driver and PX25 output tubes, while the two Power Units provide the ample current needed to drive the speakers, and have no voltage gain. In other words, the HAS-GR system is a Unique Modular Hybrid Integrated Power Amplifier in a class of its very own.

Please see Features for more details.
