What You Need to Know
What Is an Integrated Amplifier?
An integrated amplifier puts two things in one box. The first is a preamp, which picks your source and controls the volume. The second is a power amp, which drives your speakers. Having both in one unit is simpler. It takes up less space. And it removes extra cables from the signal path.
What Is the X-i75?
The Advance Paris X-i75 is the starting point of the Advance Paris Classic Line. It’s designed in France. And for its price, it comes loaded with features you don’t often see.
It puts out 75 watts per channel into 8 ohms (110 watts into 4 ohms). That’s enough to drive most bookshelf and floorstanding speakers with ease. Inside, there’s a built-in DAC for digital sources, a phono stage for turntables, a headphone output on the front, a subwoofer output, and a Hi-Bias switch that we’ll explain below. That’s a lot of gear in one box.
The look is clean and striking. A deep black glass front panel with a single large aluminum knob in the center. It shares the same design family as the X-P700 preamp. Reviewers have praised both the sound and the build quality.
What Is Hi-Bias Mode?
The X-i75 is a Class A/B amplifier. That’s the standard type for good solid-state amps. It runs cool and sounds great across a wide range of volume levels.
Here’s the catch with Class A/B: at low volume, the amp runs in pure Class A mode. Class A is the smoothest, most natural-sounding way an amp can work. But as volume goes up, the amp switches to Class B. Class B handles power better but isn’t quite as smooth.
The X-i75 has a toggle switch on the back called Hi-Bias. When you flip it on, the amp stays in Class A for more of its power range. It runs warmer. It uses more power. But reviewers liked the result.
According to the FutureAudiophile review (June 2025), Hi-Bias gave the amp a weightier sound without being too warm or dark. The SoundStage Access review (February 2025) said the X-i75 sounded warmer and fuller in Hi-Bias mode. Try both settings and pick the one you like best — that’s what the switch is for.
Built to Connect Everything
The X-i75 is made to be the center of your system. Here’s what you can plug into it.
For analog sources: Seven line-level RCA inputs for a CD player, streamer, or anything else with analog output. Plus a dedicated MM phono input for a turntable — no separate phono preamp needed.
For digital sources: Two coaxial S/PDIF inputs, one optical Toslink input, a USB-B input for computer audio (up to 24-bit/192kHz using an XMOS chip), and a USB-A input for playing music from a flash drive. All digital inputs route to a built-in Wolfson WM8740 DAC — a 24-bit/192kHz converter.
For Bluetooth: A port on the back accepts the optional X-FTB01 (aptX) or X-FTB02 (aptX HD) module. These are sold separately.
For outputs: Speaker binding posts for your main speakers. A headphone jack (6.35mm) on the front. A subwoofer RCA output. Pre-out and amp-in connections if you want to use the X-i75 as just a preamp or just a power amp in a bigger system.
Who Is This Best For?
You want one amp that handles analog sources, digital sources, a turntable, and headphones — without extra boxes.
You’re building your first serious hi-fi system and want an amp that won’t hold you back as your sources get better.
You own a turntable with an MM cartridge and want to plug it straight in.
You care about how your gear looks. The black glass and aluminum design is striking at any price.
You want to try Hi-Bias Class A sound without paying for a full Class A amp.
How Does It Connect to Your System?
The X-i75 drives your speakers directly. Connect them to the binding posts on the back. It works with 4-ohm and 8-ohm speakers.
All source connections are on the back panel. Turntable goes to the phono input. CD player or streamer goes to any of the seven RCA inputs. Computer audio goes to the USB-B input (up to 24-bit/192kHz). A flash drive goes to the USB-A input. Digital sources with coaxial or optical output connect to the matching digital inputs — all routed through the Wolfson DAC.
For Bluetooth, plug in the optional X-FTB01 or X-FTB02 module (sold separately) to the expansion port on the back.
The Hi-Bias switch is also on the back panel. Make sure the amp has good airflow around it when Hi-Bias is on, since it runs warmer in that mode.
A remote control is included. It handles volume, input, and tone settings. It also works with other Advance Paris products.

Features & Specifications
75 Watts Per Channel of Clean Power
The X-i75 puts out 2×75W into 8 ohms and 2×110W into 4 ohms. That’s enough for most bookshelf and floorstanding speakers. The SoundStage Audio-Electronics Lab measured 120W into 4 ohms under real-world conditions, confirming the amp handles loud, complex music without running out of power.
Hi-Bias Mode — More Class A Sound
A switch on the back panel turns on Hi-Bias mode. This keeps the amp running in Class A — the smoothest, most natural-sounding mode — for more of its power range. The amp runs warmer and uses more energy, but reviewers at SoundStage Access and FutureAudiophile both preferred the sound this way. Make sure the amp has good airflow when Hi-Bias is on.
Built-In Wolfson WM8740 DAC
All digital inputs feed a Wolfson WM8740 DAC — a 24-bit/192kHz converter. A DAC turns digital music into the analog signal your speakers need. This one handles all common digital formats up to 192kHz. Reviewers at AVForums (April 2024) confirmed it covers everything most listeners will use.
MM Phono Stage for Turntables
A dedicated moving magnet (MM) phono input lets you plug in a turntable with no extra equipment. Input impedance is 47kΩ, the standard for MM cartridges. Moving coil (MC) cartridges need a separate step-up device.
Tons of Inputs
Seven line-level RCA inputs. One MM phono input. Two coaxial digital inputs. One optical digital input. One USB-B input for computer audio (XMOS chip, up to 24-bit/192kHz). One USB-A input for flash drive playback. One Bluetooth expansion port (accepts the optional X-FTB01 or X-FTB02 module, sold separately). Pre-out and amp-in connections round things out.
Headphone Output
A 6.35mm (quarter-inch) headphone jack on the front panel lets you listen privately any time. No need to unplug anything from the back.
Subwoofer Output
A dedicated RCA subwoofer output makes it easy to add a powered sub for deeper bass. Crossover settings are handled on the subwoofer itself.
Toroidal Power Transformer
A toroidal transformer provides the power foundation for the amp. This type of transformer is preferred in audio gear because it delivers power efficiently and creates less magnetic interference than other designs.
Remote Control Included
The included remote handles volume, input, and tone settings. It also works with other Advance Paris products, so you can control a full system from one remote.
Striking Design
The front panel is deep black glass with one large aluminum control knob in the center. It’s part of the Advance Paris Classic Line, designed in France. At 430 mm wide (about 17”), it fits standard audio racks.

Frequently Asked Questions
Frequently Asked Questions
What is Hi-Bias mode, and should I use it?
Hi-Bias keeps the amp in Class A — the smoothest-sounding mode — for more of its power range. At normal listening levels, most of your music plays in that Class A window. The amp runs warmer, so give it room to breathe. Reviewers at SoundStage Access (February 2025) and FutureAudiophile (June 2025) both preferred Hi-Bias. Try both settings and pick the one you like.
Does the X-i75 include Bluetooth?
No. Bluetooth is optional. The back panel has a port that accepts the X-FTB01 (aptX) or X-FTB02 (aptX HD) plug-in module. These are sold separately. Both are tiny, draw power from the amp, and need no extra cables.
Does the X-i75 work with a turntable?
Yes. It has a dedicated MM (moving magnet) phono input at 47kΩ. Plug in any turntable with an MM cartridge — no separate phono preamp needed. MC (moving coil) cartridges need a separate step-up device connected to one of the line-level inputs.
What’s the difference between the X-i75 and the A10 Classic?
The X-i75 is the entry-level Advance Paris integrated amp. The A10 Classic is the step up. The A10 adds a tube preamp stage for a warmer character, a more powerful ESS9038 DAC with DSD support, HDMI ARC for TV audio, and more output power. The X-i75 is a great all-in-one amp at its price. The A10 is a different class of product built around a hybrid tube/solid-state design.
Can I add a subwoofer?
Yes. A dedicated subwoofer RCA output is on the back panel. Connect it to any powered sub. The sub handles its own crossover settings. Call us at 800-942-0220 if you need help picking one.
Can I use the X-i75 as just a preamp or just a power amp?
Yes. Pre-out and amp-in connections on the back panel let you split things up. Use pre-out to send the X-i75’s preamp signal to an external power amp. Use amp-in to feed the X-i75’s power amp from an external preamp. This gives you room to grow your system over time.
What else do I need?
Speakers and a source — a turntable, CD player, streamer, or computer. Plus cables to connect them (not included). The remote control and power cable come in the box. For Bluetooth, add the optional X-FTB01 or X-FTB02 module.
Is the single-knob control easy to use?
The X-i75 has one central knob that handles input, volume, and tone through a push-and-turn system. A few reviewers noted a short learning curve. The included remote control makes day-to-day use simple once the amp is set up. Call us if you’d like a walkthrough before you buy.
