Audiomania expert verdict

An ultra-compact class-D network amplifier: 2 × 100 W into 4 Ω, HDMI ARC, AirPlay/Spotify Connect/DLNA, Bluetooth 5.0 aptX HD, a PCM5121 24/192 DAC, a sub output — at 38,990 ₽ “no rivals with network features”. In specialists' experience a “balanced, dynamic” sound with budget bookshelf and floorstanding speakers in 16–30 m²; no phono stage, a non-localised app and limited headroom for large rooms.

In brief

Best if you are looking for:

  • a compact hub for a TV + phone + streaming system: HDMI ARC with TV-remote volume, AirPlay, Spotify Connect, DLNA, aptX HD Bluetooth — 19.8 × 4.6 cm, 1.3 kg AI draft, under review
  • a first system with budget bookshelf or floorstanding speakers: Radiotehnika Alfa / Sigma 1.01, ELAC Debut B6.2, DALI Spektor 2, Monitor Audio Bronze — “no rivals with network features at this price” AI draft, under review
  • 4 Ω Soviet S-70 / S-90 speakers and rooms up to 30 m² at moderate volume: “powerful, it will drive them well” AI draft, under review
  • a 2.1 setup: a sub output that follows the master volume; a desk or gazebo — a 960 mV headphone amp, optical and line outputs AI draft, under review

Keep in mind:

  • no phono stage and the only analogue input is a 3.5 mm AUX: vinyl via an external stage, RCA sources through an adapter (“too few inputs, a pair of RCA would help”) AI draft, under review
  • the Linkplay app is not localised and vanished from Google Play — specialists suggest WiiM Home or Triangle AIO; Yandex/VK only via AirPlay or Bluetooth AI draft, under review
  • HDMI CEC is volume only: the TV does not switch the amp on or off; the line output is fixed — active speakers cannot be connected AI draft, under review
  • 100 W is claimed only into 4 Ω from a 32 V × 5 A (160 W) external PSU: headroom for loud listening in big rooms is limited; for speakers of Vita 2.05 or ELAC DBR62 level specialists name class-AB amplifiers (Audiolab 6000A/7000A) AI draft, under review

What the experts say

  • «Сегодня компактные домашние мультимедийные системы на вершине прогресса. Ведь это очень удобно, когда в одном устройстве есть и усилитель, и ЦАП, и доступ к контенту. Если несколько лет назад такие компоненты считались дорогими, то теперь шаблоны рвёт Radiotehnika RTM01.»

Sound character

Specialists describe the sound as “balanced and dynamic” with “good speaker-control parameters”, “detailed and spacious” with the Sigma 1.01, bass “more dynamic” than an AV receiver's; against the SMSL A300 — “more detailed and articulate”. AI draft, under review[4]

Buyers add nuance: after an SMSL AD18 “the sound got sharper, the bass deeper and a bit harder, every instrument much clearer”; from the TV over HDMI “clean but bass-light”; at minimum volume “somewhat plain”, better from 20%. Against the ELAC DS-A101-G a specialist gives the ELAC the edge in “bass/mid balance” and detail. AI draft, under review[5]

Technologies and construction

  • Class D, 2 × 100 W into 4 Ω in a 4.6 cm box

    What it is: A class-D amplifier (confirmed by specialists) with 2 × 100 W into 4 Ω; powered by an external 32 V / 5 A brick; 19.8 × 4.6 × 15.3 cm, 1.3 kg.

    Practical benefit: Enough for 4 Ω S-70/S-90 and budget floorstanders; “hardly heats up even at sustained full power” (review).

  • Network player (Linkplay)

    What it is: Wi-Fi 2.4 GHz / Ethernet; AirPlay (1, receive), DLNA, Spotify Connect; in the app — Qobuz, Tidal, iHeartRadio, Napster, internet radio (the amp talks to the server itself); network files up to 24/192.

    Practical benefit: “At this price with network features there are simply no rivals” (specialist); Russian services via AirPlay/Bluetooth.

  • HDMI ARC with TV-remote volume

    What it is: An HDMI ARC input for TV audio; CEC carries volume but not power on/off.

    Practical benefit: The TV through stereo speakers with one remote for volume; “connect the TV over HDMI ARC” (specialist).

  • Bluetooth 5.0 aptX HD

    What it is: A Bluetooth 5.0 module with the aptX HD codec — receive only.

    Practical benefit: An Android phone (Yandex, Sber Zvuk) is the simplest route; it does not transmit to Bluetooth speakers.

  • Burr-Brown PCM5121 DAC (24/192)

    What it is: A Burr-Brown PCM5121 DAC, streams from 24-bit/44.1 to 24-bit/192 kHz; an optical input for PC/TV.

    Practical benefit: A computer and TV digitally without an external DAC; the streamer itself can feed an external DAC over optical.

  • Sub, line and optical outputs

    What it is: A subwoofer output (follows the master volume), a fixed 780 mV line output, an optical output.

    Practical benefit: A 2.1 system with any active sub; an external-DAC upgrade; active speakers from the line out — no.

  • 960 mV headphone amplifier

    What it is: A built-in headphone amplifier with up to 960 mV RMS output.

    Practical benefit: By §4.9.18 ~1 V suits low-impedance, sensitive headphones (dongle class); high-impedance studio cans — no.

  • Bass/treble, IR remote

    What it is: Separate treble and bass adjustment from the remote or the encoder; an IR remote with 5–7 m range.

    Practical benefit: Room and TV tuning; the app has no full EQ, and the remote may clash with the TV's IR remote (reviews).

FAQ

›Which Android app — Audio System has vanished from Google Play?
“Checked — the app has indeed gone from Google Play. You can install the APK, or use the WiiM Home app, which runs on the same platform” (specialist, 2025-10). A buyer confirmed: “WiiM controls the amplifier”. Another option is Triangle AIO. The app is not localised.
›Does it support Yandex Music, Sber Zvuk, VK Music?
Yandex Music — “via AirPlay and Bluetooth”; Sber Zvuk from Android — via Bluetooth, “with a Qobuz subscription you can stream losslessly over the home network”. Native integration of Russian services “is not planned” — it is a Linkplay platform.
›Is there a phono stage? Can I connect a turntable?
“There is no built-in phono stage, only a line input” — a turntable connects “via the AUX socket… and must have a built-in or external phono stage” (e.g. Radiotehnika PH001).
›Can the TV remote control it over HDMI CEC? Does it switch on with the TV?
“The TV does not send power on/off commands to the amplifier, but volume is controlled from the TV remote” (specialist, 2024-02; confirmed 2025-03). An earlier “no control commands” answer was corrected.
›Does the sub output follow the volume control?
Yes: “volume is adjusted for the speakers and the subwoofer together” (specialist). For Alfa 1.02 MKII in 20 m² a Wharfedale WH-D8 was recommended instead of a Nobsound.
›Is 100 W nominal, RMS or peak? Enough for the S-90?
“The manufacturer does not specify, but I suspect RMS” (specialist); power is rated only into 4 Ω. For the S-90 “headroom is needed — the RTM01 suits noticeably better” than the RTM02 v2; the S-70 (86 dB, 4 Ω) “will do”. The stock 32 V × 5 A = 160 W PSU limits sustained peaks — headroom for loud listening in big rooms is modest.
›Can I connect a centre channel or build 5.1 on it?
No: “the unit is designed for one pair of speakers”, “a centre channel does not connect to a stereo amplifier”. In a 5.1 system it can only serve as a power amp alongside an AV receiver (via AUX).
›How do I connect a computer?
“A PC connects via optical or DLNA” (specialist); there is no USB input. Network files — FLAC, WAV, AAC, APE, WMA, MP3 up to 24/192.
›Will it drive the Sigma 1.01 bookshelf in 16 m² (blues, rock, loud)?
“The amplifier will open up the speakers in your conditions — detailed, spacious sound. To get the maximum from them, though, consider a higher-level amplifier: the AudioLab 6000A” (specialist, 2026-06).
›Can I connect active speakers or Bluetooth speakers?
No: “active speakers cannot be connected — the line output is fixed, without volume control”; Bluetooth is “receive only”. The optical output is for an external DAC. The model with a display is the RTM02 v2.
›Can I connect a centre channel?
No: a stereo amplifier drives two channels; multichannel cinema needs an AV receiver.

    Отличный усилитель. Покупался совместно с акустикой Alfa 1.02 MKII. Легкое приключение. Разнообразие вариантов подключения. Все интуитивно понятно. Синхронизировался с IPhone через приложение. Отрабатывает свою стоимость в полном объёме. Соотношение цена-качество.

  • Андрей Б., Рязань · 2025-01-26Goodverified purchase

    Он реально маленький. Меньше чем кажется на обзорах. Тактильные впечатления понравились, чувствуется премиум в сборке, упаковке, деталях. Настройки через приложение не понравились. Они дублируют пульт - настройка низких и высоких частот. Полноценного эквалайзера нет в приложении. Значит через телефон и ПК получится играть так как надо. С ТВ по HDMI звук чистый, но без низов, даже если их добавить через пульт. Шумов и щелчков в ожидании нет совсем, очень приятно. Не понравилось близкое расположение выходных контактов на колонки, но компактный размер оправдывает это. В итоге я остался доволен.

  • Дмитрий Б., Москва · 2025-01-26Excellentverified purchase

    Всё супер. На след день позвонил в магазин, подсказали некоторые моменты по настройке подключения. Всё прошло отлично. Спасибо!

  • Андрей З., Смоленск · 2024-12-11Excellentverified purchase

    Неплохой усилитель. Звук понравился. Из неожиданностей - это то, что он практически не греется, даже на длительной полной мощности! Работал с акустикой Союз 130 АС 002.

  • Владимир И., Мурманск · 2024-10-03Excellentverified purchase

    Неожиданно хороший звук! Работает в паре с ELAC FS 267. Из минусов только регулировка громкости (ступенчатая, не удобно). Мало входов, добавить бы пару RCA.

  • Михаил К., Москва · 2024-09-20Excellentverified purchase

    Хороший усилитель, но через полгода перестал работать пульт дистанционного управления. Возможно ли обменять пульт или преобрести новый?

Audiomania expert opinion

The RTM01 is Radiotehnika's most-discussed amplifier: 187 messages, almost all “will it suit…”. Specialists confirm pairings with Sigma 1.01, Alfa, ELAC Debut B6.2, DALI Spektor 2, Bronze BX6, Diamond 12.3 and the Soviet 4 Ω S-70/S-90, describing the sound as “balanced and dynamic”, “detailed and spacious”; against the SMSL A300 it “sounds more detailed and articulate”. AI draft, under review[4]

The limits are honest: for Vita 2.05 “the speakers' potential is far wider than this amplifier's talent”, for DBR62 class-AB amplifiers give “more faithful sound”, and the ELAC DS-A101-G is “better balanced and more detailed”. The RTM01's strength is connectivity and price, not absolute sound class. AI draft, under review[4]
