Audison Thesis TH due - 2-Channel Amplifier with High-Res Digital Input and 1-Ω Stability
The Audison Thesis TH due is a two-channel high-performance amplifier that precisely drives front systems, controls subs, and can be bridged into a powerful monoblock when needed. With up to 750 W per channel at 1 Ω or 1500 W bridged at 2 Ω and true Class A operation in Dual Power Mode, it delivers reference-level control and detail. Digital S/PDIF and AD-Link inputs (up to 192 kHz/24 bit) directly connect Hi-Res sources. Available at Carhifi.shop.
