For me, I prioritize performance and reliability over marketing hype. My journey with the TA 2400 MK-X had a rough start—I initially ordered a B-Stock unit that arrived DOA. However, knowing the reputation and speccs for this "classic" design of amp, I didn't hesitate to order a brand-new unit, and I’m glad I did.
This amplifier is built the "old-school" way. It’s heavy (nearly 20kg) and houses a massive toroidal transformer, which is exactly what you want when driving subwoofers. Unlike some modern, lightweight Class D amps that struggle with low-frequency transients, the TA 2400 provides the raw current and headroom needed to keep the low-end tight and authoritative.
I am currently using it to power two subwoofers, and the performance is outstanding. It doesn't break a sweat, even during long sessions at high volumes. The cooling system is effective, and the build quality is tank-like. Yes, it’s heavy, but that weight translates into a power supply that won't fail you when the bass hits hard.
You also must be aware of its physical dimensions. This unit is exceptionally deep. Including the two metal protection tabs at the rear, it reaches a total depth of 475mm. This is a significant footprint that will not fit in standard shallow or "short" racks. You must ensure your rack case has enough clearance for both the unit and the cable connectors, otherwise, you risk damaging your wiring or the ports.
If you are looking for a high-performance power amp with an incredible price-to-quality ratio and you don't mind the weight, this is a legendary workhorse. Powerful, and reliable.
