About the (formerly Jolida) Fusion 3502P

The Fusion 3502P is a high-performance stereo tube power amplifier from Black Ice Audio, originally developed under the Jolida brand. It features a redesigned circuit on a steel chassis with upgrades including ESA clarity coupling capacitors, high-speed diodes, and DC voltage to preamp tubes for reduced noise and enhanced clarity. Tube bias is switchable for 6550, KT88, KT120, KT150, or EL34 tubes. It can be used as a power amp with bypass functionality. Custom wound audio transformers with German grain-oriented silicon steel core support 4 or 8 ohm loads. Components include ALPS audio potentiometer and gold-plated RCA inputs. Jolida production ceased in 2017, and Black Ice Audio provides repair services but no technical support, remotes, or manuals for legacy gear. The Fusion line offers superior noise floor, tone, detail, bass, soundstage, and imaging compared to original Jolida products.
