Compact 300W x2 Class D Amplifier

The lelisten V3 is a stereo Class D power amplifier rated at 300 watts per channel into a 48 V supply. It uses the TPA3255 chip with Japanese NCC, ELNA and German WIMA capacitors plus Sumida inductors. Measured SINAD reaches 88 dB, signal-to-noise ratio 110 dB and noise floor 140 uV. The compact chassis suits desktop, bookshelf or home-theater installations.

Buyers Who Need Op-Amp Rolling vs Fixed-Gain Users

Socketed NE5532 op-amps let enthusiasts swap to compatible 8-pin dual types for tonal tuning. Builders who prefer a fixed-gain design with no user-serviceable parts should consider other models. The amplifier drives passive bookshelf or tower speakers from 2 to 8 ohms without additional cooling hardware.

48 V Power Supply Requirement

Operation requires the included 48 V external power supply; no other voltage is supported. The whole-body heatsink with top and bottom vents handles thermal loads at the rated 600 W total output. Confirm that your passive speakers match the 2-8 ohm load range before connecting.

Questions about this item

What speaker impedance range does the TPA3255 Class D amplifier support at 300W per channel?

The V3 drives speakers from 2 to 8 ohms per channel, delivering up to 300W into each load with the included 48V power supply.

What physical clearance does the whole-body heatsink design require for proper cooling?

Leave at least a few centimetres of open space above the top vents and below the bottom vents so air can move through the chassis without obstruction.

How are the stock NE5532 op-amps swapped, and which step is most often missed?

Power off, unplug the 48V supply, gently lift each 8-pin DIP chip with a small tool, align the notch on the replacement op-amp, press firmly until seated, then restore power — skipping the power-off step risks damaging the new op-amps.
