Audison Thesis TH uno - 1-Channel Monoblock Amplifier with Class-A and Full-DA-HD
The Audison Thesis TH uno is a 1-channel amplifier that combines analog Class-A sound quality with digital signal processing. You get up to 2300 W into 1 Ω for powerful subwoofer setups and, if desired, pure Class-A operation with 200 W for focused music listening. The integrated 24-bit/192 kHz DAC and Audison Full-DA-HD support make the TH uno the perfect solution for high-res sources.
