Wiim Amp Ultra Streaming Amplifier (Each)
Unleash Studio-Quality Sound
Meet the WiiM Amp Ultra – our most advanced streaming amplifier yet. Built for music lovers, home theater buffs, and smart home fans, it delivers stunning 100W per channel (8Ω) with ultra-low distortion, pushing high-fidelity audio to every corner of your space. Whether it’s vinyl, Spotify, or cinematic surround sound—you’ll hear it like never before.
Beautiful Inside and Out
Designed to stand out and fit in, the Amp Ultra features a sleek unibody aluminum chassis and a vibrant 3.5″ glass-covered touchscreen. Easily control playback, switch sources, view album art, and more—all at your fingertips.
Flagship Components, Flawless Fidelity
Under the hood, the Amp Ultra is powered by top-tier components:
ESS ES9039Q2M SABRE DAC
Dual TI TPA3255 Class-D amplifiers
Six TI OPA1612 op-amps
Combined with Post Filter Feedback (PFFB) technology, it delivers clean, detailed sound with consistent performance across all speaker loads—perfect for bookshelf, floor-standing, or in-wall speakers.
Post Filter Feedback Technology
At the core of the WiiM Amp Ultra’s superior sound is its advanced Post-Filter Feedback (PFFB) technology, a cutting-edge refinement system that minimizes distortion, enhances clarity, and ensures consistent sound quality across different speaker loads. Unlike traditional amplifiers that suffer from load-dependent performance variations, PFFB dynamically compensates for these inconsistencies, delivering a more accurate, balanced, and natural sound signature. The result? A wider soundstage, richer details, and an immersive listening experience that faithfully reproduces every note with precision and depth.

Polk Reserve R200 Bookshelf Speaker (Pair)
WHAT BETTER SOUNDS LIKE
Life is good. You got the better house. The better furniture. The better car. But, why haven’t you gotten better speakers yet?
With understated elegance, the Reserve line has a minimalist design with universal appeal. Inheriting Polk’s flagship transducer array, the speakers produce exceptional sound rivalling competitor speakers that sell for twice the price. Immerse yourself in your favourite musical recordings or your weekly movie night with the new Polk Reserve.
High Definition Pinnacle Ring Radiator Tweeter
Over 40 years of tweeter innovation, design and prototyping has led to the development of the new 1” high definition Pinnacle ring radiator tweeter. Developed by Polk Audio, it delivers ultra-clear, crisp highs without unwanted coloration or distortions. The Pinnacle tweeter features a finely tuned waveguide that dramatically improves the dispersion of high frequency energy ensuring a broad “sweet spot” while the critically damped rear-chamber helps defeat any unwanted resonances. Hi-Res certified, the Pinnacle Tweeter is designed for today’s two-channel music listening as well as multi-channel 3D audio found in movies, sports, and video game soundtracks.
Polk developed the Turbine cone specifically for our flagship products to ensure the natural reproduction of the mid-range, to which human ears are particularly sensitive. The Turbine cone combines Polk’s proprietary foam core and molded Turbine geometry which dramatically increases stiffness and damping, without adding mass. You will hear every detail and experience a smooth, detailed mid-range and effortless bass.
Polk Newly Patented X-Port (ETF)
Polk’s newly patented X-Port incorporates an Eigentone Filter (ETF) offering distortion-free, effortless bass. Consisting of a set of closed-pipe absorbers that are specifically tuned to catch and eliminate traditional speaker distortions. X-Port ensures that the upper bass and mid-range are free of port and cabinet resonances for smooth, detailed audio.
Reserve R200 bookshelf speakers are available in two modern finishes: Midnight Black and Satin White (coming mid-2021).
These bookshelf speakers can be used for the front stage of any home theatre as well as side and/or rear surrounds. To add immersive vertical sound, Reserve R900 height modules are compatible (R900 sold separately).
High-Resolution Certified
Your sound is only as good as your source. With Hi-Res Audio certification, the Polk Reserve R200 delivers a clear and detailed high-end response. Female vocals are particularly smooth and without colouration.
