DESCRIPTION
Due to the new power supply technology the 725 preamplifier has an even more breathtaking three-dimensional sound quality than its predecessor the 720 already did. Unsurpassed wealth of detail. Incredible punch at low frequencies. Distortions and noise could be reduced even further. The preamplifier is the command centre of your high fidelity chain. In tests its sound quality has proved to be second to none.
