Ultra-performance 8-channel D/A converter and preamplifier

Apogee performance, Motu price

Analog topology by Okto Research employing high-speed fully-differential operational amplifiers results in exceptionally low harmonic and intermodulation distortion. Our approach to power supply design renders extremely clean analog output, free of undesirable RFI and with undetectable level of mains harmonics. Measurements below were taken with the Rohde & Schwarz UPV audio analyzer.
