Tube Power Amp Reviews

I tested the Audio Research D-160B using top-quality turntables like the Goldmund and SOTA-Sumiko arm combination, top quality cartridges, and speakers like the modified Quad ESL-63s, Thiel CS3s, Spica TC-50s, and Fuselier 3.3s. Preamplifier was the Audio Research SP-10. I have used them with Compact Discs and a wide range of FM Tuners. I have mixed and matched cables, including the Straightwire, Petersen, Discrete Technology, Audiosource, and Monster Cable Interlink Reference.—Anthony H. Cordesman
