Things to Know
Topping L70
- ⚠Rear panel is extremely crowded; thick XLR cables can be difficult to unplug.
- ⚠The 'clicking' sound of the volume relays is audible inside the chassis when changing volume (normal but surprising to new users).
- ⚠Display menu system is somewhat cryptic (abbreviations like 'H-G' for High Gain).
Topping Pre90
- ⚠Input impedance is relatively low (10kΩ balanced), which may not pair well with some vintage tube sources.
- ⚠Remote control range is narrow and requires precise pointing.
- ⚠Sound can be perceived as 'lean' or 'dry' by those used to colored preamps.
