🔥 **HiFi Rose RA180 — Ultra-Wideband Wolverine in a Machined-Aluminium Tux** *Four channels, two hearts, one mission: make every other “reference” amp feel like a polite dinner gue st.* --- 🔊 **Quad-Core Carnage** * **200 W × 4 @ 4 Ω / 8 Ω** — bi-amp a pair, tri-amp a mansion, whatever. * Flip the **BTL switch** and unleash **400 W × 2** of monoblock mayhem. * GaN-FET output stage swings 1 MHz like it’s pocket change, so transients land before you know they left. 🎯 **Full-Range Sniper Scope** * **10 Hz – 90 kHz (±1 dB)** bandwidth: organ pedal to bat-sonar without a hiccup. * **0.005 % THD @ 50 W** — distortion registers lower than your favourite bass drop. * **Damping factor > 150** keeps woofers at military parade-ground attention. 🎚️ **Tone-Craft Tool Kit** * **On/Off tone stack** ±15 dB @ 100 Hz & 10 kHz — add thunder or air, then vanish it with a click. * **Subsonic filter 50 Hz** for vinyl sessions that shouldn’t jiggle the drapes. * **Continuously-variable crossover (600 Hz – 6 kHz)**: bi-amp your horns without a calculator. 🎻 **Vinyl Sorcery Built-In** Swappable **MM / MC phono** stage with *five* turnover options and *six* roll-off curves — from textbook RIAA to “1970s Japan press deep cut.” Your records, your rules. 📈 **Need-to-Know Spec Hit** | Stat | Reality Check | | ------------------ | ------------------------------------- | | **Output Power** | 4 × 200 W (4/8 Ω) • 2 × 400 W BTL | | **Inputs** | 3 × RCA • 1 × XLR • MM/MC phono | | **S/N** | 107 dB line • 80 dB (MM) • 60 dB (MC) | | **Damping Factor** | > 150 | | **Weight / Size** | 16.7 kg • 430 × 350 × 110 mm | | **Chassis** | CNC-carved high-purity aluminium | 🖤 **Industrial Art, Korean Flair** All-aluminium shell, twin glass-covered VU meters, and bronze-anodised knobs that spin like camera lenses. Pop the hood: GaN transistors on copper buss-bars, SMPS with 800 W headroom, and PCB traces shorter than your attention span. --- 🚀 **Why Your Rack Craves RA180** Because vanilla Class-D sounds like spreadsheets. Because Class-A heat sinks your lounge. Because you want **GaN-fueled speed, analogue soul, and artillery-level headroom** in one sculpted monolith that moonlights as modern art. **HiFi Rose RA180 — wire it, fire it, watch the needles dance.** 🎧⚡ Show more
