The MX-HPA’s technical performance is stunning. Typically, distortion from 20 Hz to 40 kHz is less than 0.005%. Signal-to-noise ratio is better than 120dB (‘A’ weighted). Frequency response is ruler flat from 10 Hz to 20 kHz (-0.1dB). The MX-HPA is capable of a short-term peak of 10 watts (for one cycle) and has two gain positions: 18dB (8X) and 24dB (15X). Inputs are either balanced or single-ended. The MX-HPA will automatically convert single-ended inputs to balanced. The MX-HPA is genuinely fully balanced from beginning to end.
Product Strengths
- Exceptional build quality with an elegant, minimalist aesthetic
- Fully balanced design
- Exceptional signal-to-noise ratio (>120dB 'A' weighted)
- Versatile because it automatically converts single-ended inputs to balanced signals
- Dual gain settings for versatility with virtually any headphone impedance
Product Considerations
- May be overkill for entry-level headphones
- The twin-XLR alternative is not the only means of balanced connection
Takeaway: The Musical Fidelity MX HPA is a remarkable piece of equipment that represents a significant achievement in balanced amplification design. It delivers a listening experience that is hard to surpass with technical excellence and practical versatility.

Our take on the brand
Fully balanced design, 4 ultra-low distortion precision linear feedback circuit (PLFC)! The distortion is as low as 0.00006%, and the SNR is as low as 133dB! A total of 99 low-noise op-amps are used in a parallel design. High output power, 16 ohm output power up to 12W, 32 ohms up to 6W; The specially designed volume potentiometer greatly reduces channel deviation; 3 gears gain control, low gain is specially optimized for IEM; Pre-out function, can be used as Hi-End pre-amp; Classic retro toggle switch operation; Ultra-compact design, very suitable for desktop headphone system; High-precision low-temperature drift resistance, performance is not affected by temperature; High-quality relay and non-impact sound design; 20Hz to 100KHz(-0.5dB) frequency response; The headphone amplifier has comprehensive protections such as DC, overvoltage, and overload protection; Built-in high-efficiency and low-noise power system.
Product Strengths
- Original and stylish design
- High power output, up to 12 watts
- Overload protection
- The XLR, RCA input switch, the headphone amplifier or preamplifier switch, and the low, mid, and high gain switches are located on the back of the unit, potentially making them difficult to access
Product Considerations
- The unit uses 99 low-noise op-amps in parallel, which is considered excessive and potentially detrimental to sound quality
- The unit uses the cheapest balanced potentiometer
- The unit uses a couple of switching power supplies
- The total harmonic distortion is only at its super magical level with a very high wattage
Takeaway: The VMV amp has high power and overload protection that might work to drive headphones. It could be a great amp for someone willing to try it out.

Our take on the brand
Our Summary
Product Strengths
- Budget-friendly headphone amplifier focused on quality
- Robust all-aluminum exterior, with rigid toggle switches, and smooth volume control, giving it the same fit and finish as SMSL's higher-end HO200
- Delivers a clean, neutral, and transparent sound, faithfully reproducing the source audio without adding coloration
- Extremely low noise floor
- Versatile due to its three gain levels (low, mid, high) and its ability to drive both sensitive IEMs and harder-to-drive headphones
Product Considerations
- Lacks balanced and unbalanced outputs for connecting to powered speakers, functioning solely as a headphone amplifier
- Does not have preamp capability
- Reviewers have noted average microdetails
- While the design looks smart and subdued, the tempered glass panel easily grabs fingerprints, requiring frequent cleaning

Our take on the brand
Our Summary
Product Strengths
- Enjoyable overall presentation with a punchy bassline, slightly euphonic midrange, and crystalline treble response
- Expansive soundstage that allows the music to breathe and come to life
- Enough power to drive most moderately hard-to-drive headphones, even those with higher impedance
- Detailed and textured vocal range that is a touch more forward and warmer than clinically accurate
- Tactile controls allow quicker access to changing any of the settings on the device
Product Considerations
- Slight bright tilt, which may require careful pairing with other components
- Bass is present, but slightly rolled off
- Lacks a screen, which some users may find to be a downside
- Balanced connection is present for convenience, as the amplifier itself is not a differential design—meaning it's single-ended by nature
Comparisons (according to reviewers)
- SMSL SH-8s bass tends to be a touch more forward, SMSL SH-9 delivers a slightly tighter bass line
- The SMSL SH-9 has a markedly more controlled treble response
- Both have similar power output at 16Ω, but Topping A30 Pro maintains higher power at 32Ω
- The SMSL SH-8s has a fuller instrument timbre, but Topping A30 Pro has a more euphonic vocal range
- The SMSL SH-8s has much bigger headroom, and feels more spacious compared to the Geshelli Labs Archel 2.5 Pro
- The SMSL SH-8s is clearly digging more details, and is also able to develop a wider soundstage with better separation and layering than the Topping L30
Takeaway: The SMSL SH-8s is a well-built amplifier that sounds promising. If the listener has darker sounding headphones or a darker source, the SMSL SH-8s might be worth checking out to open the sound a little bit.
