Who wins on what

Ranked by what users actually praise

Overall Impression

Sound quality impressed many owners, especially compared to older gear. Owners reported the SU-6 sounding at least as good as, if not better than, the Topping E30, with more body and depth. One user found it made a huge improvement pairing with Sennheiser HD660s headphones, adding bass and depth that felt like a different, better headphone entirely. Bluetooth LDAC support and clean optical PC connections were also appreciated for flexible listening setups.

Convenience features like remote control and auto power-on stood out. Compared to the Topping E30's inconvenient auto-standby function, the SU-6 powers on immediately with the power supply, working better with smart sockets. The included remote made switching between multiple inputs simple with a single button press, which users found practical for everyday multi-source setups involving PCs, phones, and other devices.

Long-term reliability problems were a recurring complaint among owners. Multiple users reported the unit developing distortion, cracking, or clipping sounds after months to two years of ownership, with one describing it as glitchy sound. Attempts to get support or repairs sometimes failed to resolve the issue. Some owners also noted channel imbalance at different volume levels and audible noise, leading a few to say they'd choose Topping products instead going forward.
