Overview
The X-i75 is the newest Class A/B integrated amplifier from Advance Paris. It strikes a good balance between analog and digital input options with a warm sound boasting enough power for many different loudspeaker types, plus some useful flex features like a Class-A bias mode (for lower-output “sweet-spot” performance), tone controls, and a phono input.
Here are its key specs:
Key Specifications
| Spec | Value |
|---|---|
| Power (8 Ω) | 2 × 75 W RMS |
| Power (4 Ω) | 2 × 110 W RMS |
| Frequency response (-3 dB) | 10 Hz–35 kHz |
| Total harmonic distortion (THD) | < 0.1 % |
| Signal-to-noise ratio | > 90 dB |
| Channel separation | > 70 dB |
| Input options | Many: analog (CD, tuner, aux, phono MM), digital (coaxial, optical, USB-A/B) |
| Special features | Hi Bias mode (partial Class A at low output), disconnectable preamp/amp, tone controls, subwoofer out, remote control |
What The X-i75 Does Well
With 75 W into 8 Ω (and 110 W into 4 Ω), it can drive a wide range of speakers. For many small-to-medium rooms, this is sufficient “oomph” for clarity and dynamic peaks. It particularly shows its strength when driving speakers that are more demanding or slightly harder to drive (with lower sensitivity or lower impedance). The Hi Bias switch lets the amplifier run in a more “Class A-like” mode for the first few watts, which tends to improve the linearity and reduce crossover distortion in those low-to-medium output ranges. If you often listen at moderate volume, this feature adds tonal smoothness and refinement. Something to keep in mind; While Hi Bias adds warmth and smoother low-level behavior, it comes with extra heat and power draw. For long listening sessions or heavier loads, thermal behavior might matter. Also, the full benefit of Hi Bias is in moderate volume regimes; when pushed hard, the Class AB section takes over, so extreme dynamics or high SPLs may expose limitations.
The mix of analog and digital inputs — USB-B (for computer), USB-A, optical, coaxial, analog RCA, phono gives fantastic flexibility. If you own both digital sources (streamers, PC) and analog (turntables, CD), you won’t need many external converters or adaptors. Also, a preamp-out / amp-in (“disconnectable preamp/amp”) is useful for future upgrades or adding specialty gear. Feedback from customers and reviewers suggests the sound is warm without being overly colored, with a good sense of detail, dynamics, and musicality. The high S/N ratio and channel separation help with clarity, imaging, and staging. The tonal controls (bass, treble, balance) also allow tailoring to room or speaker.
It has a clean, somewhat classic look. The internal power supply (toroidal transformer) and decent heat-sink design suggest solid engineering; the chassis and layout seem well appreciated in reviews. It’s not overly massive (about 8.6 kg), so manageable in many furniture setups.
Overall Impression
The Advance Paris X-i75 is a strong mid-tier integrated amp. It offers excellent value for what it brings: a well-rounded feature set, good power, a warm yet detailed sound, and flexibility for both analog and digital sources. It makes sense for someone who wants one box to do a lot without having to piece together many components.
If your priorities are neutrality above all else, or pushing extremely demanding speakers / huge rooms, there will be other amps that outstrip it in raw performance. But for balanced, enjoyable, musical listening — this unit delivers, and few rivals at its price point offer as much connectivity and usable power.
