🧾 Overview
The Fezz Audio Argentum X20 is a no-compromise high-end MC step-up transformer, handcrafted for the most demanding low-impedance moving-coil cartridges. Using 99.9% pure silver wire wound on a nanocrystalline high-permeability core, and employing dual shielding with mu-metal and pure OFC copper ribbon, it guarantees ultra-low noise, a bandwidth from 10 Hz to 100 kHz, and THD below 0.01%. With a 1:20 step-up ratio, the Argentum X20 unlocks the full potential of top-tier cartridges such as Ortofon, Lyra, Dynavector, Hana, and Goldring.
✅ Key Features
✅ 99.9% pure silver windings on nanocrystalline anisotropic high-μ core
✅ Double shielding: mu-metal (magnetic) + OFC copper ribbon (electric)
✅ 1:20 step-up ratio (26 dB) — ideal for very low-output MC cartridges
✅ Recommended load: 47 kΩ (MM phono input)
✅ Optimized for cartridges with 1.5–9 Ω internal impedance
✅ Bandwidth: 10 Hz – 100 kHz (Z = 10 Ω)
✅ THD < 0.01% at rated level — transparent and natural
✅ Solid chassis: 2.5 kg, compact form factor (120 × 95 × 212 mm)

Let customers speak for us
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.
