Allnic Audio M-5000 Titan KT150/KT170 Monoblock Power Amplifiers (pair)

Information

Allnic Audio’s M-5000 TITAN is one of the world’s most recognized reference-class power amplifiers, boasting incredible resolution, overwhelming dynamics, exceptional driving power, and industry-standard low-noise/low-distortion characteristics. Utilizing eight KT-150 power tubes, it delivers a powerful and stable output that can be described as an “iron fist in a velvet glove.”

Specifically, the M-5000 TITAN employs an intelligent design that seamlessly bridges Pure Class A and Class AB operation, realizing extremely delicate and pure sound quality at low outputs while simultaneously delivering massive energy at high outputs.

Hybrid Bias System (Class A & AB) The M-5000 TITAN is equipped with a sophisticated driving system to achieve both high fidelity and high output.

• Class A Operation: Operates in Pure Class A up to 125 watts, maximizing the sweet and vivid sound quality unique to vacuum tubes.
• Class AB Operation: Naturally transitions to Class AB for outputs exceeding 125 watts, providing powerful energy up to a maximum of 400 watts to effortlessly control large-scale loudspeakers.

Powerful Driving Circuit Allnic emphasizes the importance of low-noise, high-output driving circuits in all amplification devices. In the M-5000 TITAN, E55L (8233) tubes are driven in triode mode, utilizing a load of approximately 450Ω and 20mA of current. Compared to typical amplifiers based on 12AU7 or 12BH7 driver tubes (47kΩ load, 2–3mA current), this provides a level of difference in musical density and dynamics that can be directly felt.

“Full Engagement” Output Transformer Conventional output transformers use preset secondary windings to accommodate 4Ω, 8Ω, and 16Ω loads, but only one winding operates at a time while the others remain idle. Allnic’s “Full Engagement” output transformer keeps four independent secondary windings connected at all times. This completely blocks efficiency loss and distortion from parasitic vibrations, delivering maximum energy to the speaker.

Large Nickel/FeSi Core Output Transformer By using a massive 114mm output transformer with a Nickel/FeSi alloy core, high inductance is secured even with fewer windings. This results in an overwhelmingly wide frequency bandwidth and deep low-frequency resolution.

Soft Start Circuit & Protection System

• Soft Start: Supplies high voltage only after sufficient warming up, dramatically extending the lifespan of the vacuum tubes.
• Individual Fuse Protection: Individual fuse protection circuits are applied to every power tube, ensuring the stability of the device.

Analog Power Tube Current Monitor Independent analog meters are installed for each output tube, allowing real-time monitoring of the bias status. Anyone can easily perform precise adjustments using the bias knobs on the front panel.
