Advance Paris X-i50 BT — Integrated Amplifier with Bluetooth
The X-i50 BT is the entry point to the Advance Paris Classic Line amplifier range — a pure analogue integrated amplifier with built-in Bluetooth and a phono stage, designed for listeners who want serious hi-fi sound quality without the complexity or cost of streaming-equipped models. There's no DAC, no Wi-Fi, no network streaming, no display showing track titles — just a well-engineered Class A/B amplifier with a generous array of analogue inputs, a toroidal transformer, and the kind of musical, non-fatiguing presentation that Advance Paris is known for. At 2 × 50 watts into 8 Ohms, it's compact and affordable, but it punches well above its price point.
Hi-Fi Choice, reviewing the X-i50 BT against amplifiers costing several times more, noted striking similarities to the Electrocompaniet ECI 80D — a highly regarded amplifier at six times the price — praising the Advance Paris for its fluid, supple, tonally rich character. That's a remarkable endorsement for an entry-level product, and it speaks to the quality of the circuit design and component selection that Advance Paris has invested in at this level.
Amplification and High-Bias
The amplifier section delivers 2 × 50 watts RMS into 8 Ohms and 2 × 65 watts RMS into 4 Ohms through a Class A/B topology, driven by an oversized toroidal transformer. The lean circuit topology — short signal paths with minimal components in the chain — contributes to a clean, transparent sound with low colouration. A rear-panel High-Bias switch extends the amplifier's Class A operating window, enriching the sound at moderate listening levels with added warmth, texture, and midrange detail. For bookshelf speakers and moderate-sensitivity floorstanders in small to medium rooms, the X-i50 BT provides more than enough power and control for engaging, room-filling sound.
Connectivity
The X-i50 BT's analogue connectivity is remarkably generous for an amplifier at this price. Eight RCA inputs cover a wide range of sources: one dedicated CD input, one tuner input, four auxiliary inputs, one general line-level input, and one switchable phono input with a built-in MM phono stage (47kΩ input impedance, 2.5mV sensitivity) for direct turntable connection. A front-panel USB-A port accepts external music players, and built-in Bluetooth with AAC and aptX codec support provides convenient wireless streaming from smartphones, tablets, and laptops — no external dongle required. The pre-amplifier and power amplifier sections are separable via a rear-panel connection, allowing the X-i50 BT to be used as a standalone preamp driving an external power amplifier, or as a power amp driven by a separate preamp or AV processor. A front-panel 6.35mm headphone jack handles private listening. A single pair of speaker binding posts completes the output section.
Design and Build
The X-i50 BT shares the distinctive Advance Paris visual identity: a black acrylic glass front panel with a blue LED matrix display, backlit input indicators, and a clean, modern aesthetic that belies its budget positioning. The steel chassis is compact at 430 × 110 × 320mm and weighs just 6kg, making it easy to accommodate in a bookshelf, TV cabinet, or desktop setup. Bass and treble tone controls offer ±10dB of adjustment for room correction or personal preference, and an included infrared remote control provides full wireless operation. The build quality — acrylic fascia, solid steel casework, toroidal transformer — is consistent with products at considerably higher price points, and the overall impression is of a serious hi-fi amplifier dressed in an accessible, approachable package.
System Building
The X-i50 BT is an ideal foundation for a first serious hi-fi system: pair it with a set of bookshelf speakers and a turntable, add your phone via Bluetooth for casual streaming, and you have a complete, high-quality music system with no additional boxes required. It also makes an excellent second-system amplifier for a bedroom, study, or office. For buyers considering the step up to the PlayStream A1, the key difference is network streaming — the A1 adds Wi-Fi, Ethernet, DLNA, app control, and HDMI ARC. If you don't need those features and prefer a purer, simpler analogue amplifier with Bluetooth convenience, the X-i50 BT is the more focused and cost-effective choice.
