🧾 Overview
The KEF KASA500 is a DSP-controlled Class-D system amplifier engineered to drive KEF Ci architectural subwoofers with authority and precision. With flexible line- and speaker-level inputs, configurable DSP pass-through, and bridgeable high-power output, it’s built for clean, cinema-grade bass in custom-installed systems.
✅ Key Features

✅ Dual-channel 2 × 250 W (4 Ω) output, or bridge mode 1 × 500 W (8 Ω) for maximum impact
✅ Selectable stereo RCA line input or mono LFE RCA input for easy AVR/processor integration
✅ Stereo speaker-level inputs for flexible “tap from amplifier” installations
✅ Adjustable crossover 40–140 Hz (or software bypass via DSP presets)
✅ DSP-configurable line output: EQ preset or direct pass-through to chain additional amplifiers
✅ Multiple power-on modes: Manual, Music Sense, or 12 V Trigger control
✅ Rack-friendly: optional rack ears included (2U / 2 EIA rack space)

📝 Reviews
“Packing a chunky 250 watts per channel (at 4 ohms) … bridge the amplifier … a mighty 500 watts supply.” — Richer Sounds
“DSP controlled system amplifier contains both line and speaker level inputs … with optional high pass filters.” — Audio Affair
“Very powerful receiver. Works wonderfully with the Sonos speakers.” — Best Buy customer review
⚠️ Warning
⚠️ Warning: This amplifier may cause “just one more subwoofer” thinking, late-night DIP-switch archaeology, and the sudden belief that your walls can handle cinema SPL. Proceed responsibly.

Sound is fabulous.
I never expected such transparency and spacious soundstage from an IEM.
Simply the best "portable" headphones. Pity it was discontinued.

Lielisks pastiprinātājs! Lietoju viņu kopā ar austiņām "HifiMan Sundara" caur balancētu izeju.

Decent device for the money!I am very satisfied with the purchase!Thanks to the PremiumHIFI store!
Отличный настольный ЦАП от FiiO..
Обслуживание на высшем уровне..
Магазину и Аркадию респект!..
Заказал здесь Wiim mini. Пришло за 2 дня. Проигрыватель очень понравился, выдаёт очень хороший звук и хорошую сцену (подключаю к ресиверу через оптический кабель, поэтому звук обрабатывает цап ресивера). Также стоит очень дёшево. Не понравилось только то, что многовато высоких частот (но уже привык или пропали). Рекомендую к покупке.
Ļoti labi cenai atbilstoši skaļruņi. Kad secināju ka manā set up vājš posms varētu būt tieši skaļruņi nomainot tos neesu kļudījies ne pārtērējies. Ar tiem kas klausās mūziku kurā basi nedominē varbūt iztiks bez sabvūfera. Un ja pārdomāšu savu stereo varēšu no Klipsh skaļruņiem būvēt Dolby Atmos, Spatial mājas kino! Un šīs vara krāsas skaļruņi!
The device is good quality and it sounds really great. But it has two issues.
You cannot switch between L/R channels. It lowers both channels volume. The issue is mentioned on FiiO website.
It has LineOut function, where device is playing on max volume and you can use your computer volume bar, but it is so loud that even on the lowest set it is screaming, so you have to choose another option and adjust volume on FiiO device instead.
I wish I knew it before buying.
