Hi there. I'm using Rew+ Rephase+ Equalizer apo. My system is composed of a Topping dac which is connected to a Rotel power amplifier. I've noticed that certain tracks, where the input signal is especially weak, sound a bit recessed. The output of my dac is about 2 volts, above the sensitivity of my amplifier, which is 1,5 volts. I have thought that I have set the target of the eq too low, so reducing the input level below the sensitivity. Is this the case or simply do I need a preamp to raise the level?
