📢 Rose RS520 💪 Streaming amplifier

🔥 **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 guest.*

---

🔊 **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.

🖤 **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.
