ADCOM GFP-815 Preamplifier


Almost since the start of the brand, ADCOM has produced some of the finest components for music reproduction; this is especially true with regard to preamplifiers. In 1980’s, the GFP-1A was hailed as the best preamplifier available, and this tradition of excellence has continued ever since. GFP-815 takes visual cues from past ADCOM products while incorporating our latest designs and technologies.


Phono connectivity:

Adcom’s GFP-1A preamp featured a built-in decoder for playing records made with CX noise-reduction encoding process and separate input selectors for simultaneous listening and recording from different program sources. Walking on those lines, our engineers have developed a new phono stage catering for the resurgence in vinyl records with MM and MC configurations accessible.



The entire unit is housed in a beautiful polished stainless steel chassis that not only complements the knobs, but also your room decor. Bring home the GFP-815 preamplifier to achieve your desired listening experience.
