Product Description
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.
