One thought on “Musical Fidelity A1S Clone Class A Amplifier (BRZHIFI)”
For years, I was curious about the audio clones coming out of China but hesitant to pull the trigger. However, their quality has significantly improved over the last decade. Intrigued by the idea of pure Class A power without breaking the bank, I decided to test the waters. I picked up this unit locally in the USA for $250, and I am happy to report that the amp didn’t disappoint.
Build & Aesthetics
Right out of the box, the physical presence of this amplifier stands out. It is a genuine pleasure to handle a component made from thick, solid pieces of aluminum instead of the cheap sheet metal that is mostly used these days in amplifiers under $1000. Peeking inside, the overall quality of the internal build—from the hefty transformer to the capacitors—is very impressive for the price point.
Sound Characteristics
Looking at broader community feedback on platforms like AudioKarma and Reddit’s r/BudgetAudiophile, reviewers consistently praise this replica for its musicality, smooth presentation, and impressive midrange.
In my own listening, the standout surprise was the low end. It delivers great bass for a 20W amplifier—way tighter and heftier than what I have heard from even massive 845 tube-based amplifiers. The midrange is full, warm, and highly reminiscent of a good tube amp, making vocals sound incredibly natural.
The top end is perfectly acceptable, but it is nothing to write home about. This slightly rolled-off treble contributes to the amplifier feeling a bit veiled at times. Outside of that stellar bass response, the overall presentation is still a step back from a high-quality tube amplifier. You won’t find the same level of top-end airiness or three-dimensional, holographic soundstage here.
A1S Clone vs. Emotiva A-5
To put its performance into perspective, I stacked it against the Emotiva A-5. On paper, the Emotiva is a different beast, pushing 110W per channel into 8 ohms compared to the A1S clone’s modest 20W rating. Although the Emotiva comes in at roughly twice the price, this little Class A amp simply sounded better.
Because of that 5x power difference, the Emotiva definitely has more sheer power in the lower registers, but the A1S clone delivered much more controlled bass. When it comes to the midrange, the A1S took the crown — no contest. The top end was another clear victory for the clone; the treble on the A1S just shined, whereas the Emotiva’s high frequencies felt noticeably dry by comparison.
Final Verdict
Would I give up my 300B or 6550 based amps for this? Absolutely not, but it’s a very nice step forward for cheap transistor amps.
For $250, this Class A clone offers an incredible value proposition. While it lacks the ultimate transparency and holographic staging of a premium tube setup, its robust aluminum build, high-quality internal components, shocking bass control, and rich midrange make it an absolute steal for a budget audiophile system.
