The PROst AJ/A5/A7 amplifiers were born from a simple idea: keep the signal path short, keep the class A, and let the music breathe. Prostgear
Inspired by legendary minimalist designs, they continue a tradition where every additional component must justify its existence. Prostgear
Each model delivers between 50 and 100 watts of clean power, but the real story is how that power is translated into texture and timing. Prostgear
Instead of flashy features, you get carefully upgraded circuitry that improves current behavior in the output stage and increases perceived ease of listening. Prostgear
Producers who have used our amplifiers for decades describe the sound as non-fatiguing, readable, and surprisingly dynamic even at moderate levels. Prostgear
Transients stay sharp without becoming aggressive, and the low end carries both weight and harmonic detail.
Because the design is so focused, it becomes easier to move your attention between micro-detail and overall musical flow.
For home hi-fi users, this translates into long listening sessions where you simply forget about the gear and follow the performance.
For studio owners, it means a monitoring chain that reveals decisions clearly enough to speed up both mixing and mastering.
In both cases, the AJ/A5/A7 platform shows that minimalist class-A amplification is not nostalgia, but a living, evolving tool for modern sound.
