Ground Zero GZTA 4125X-B

New 2020 Titanium-series amplifiers bring colour to the world of amplifiers. Two sets of end caps are included in delivery. If you want your amps to stand out, install yellow end caps. If you want to have more sophisticated look, install black ones.







Many improvements have been done to inside as well. Capacitors and transistors are even better than before. Floating bias makes sound much more open on smaller volume levels and reduces distortion on higher volume levels.







GZTA-amplifiers have been among the most popular ones in the market for a long time. It is easy to understand why, since these amps offer fantastic value for money. They have good sound quality, give nice amounts of power and last but not least they are very dependable.
