If the tone controls operate like the ones in my APT/Holman preamps (see AMIR test of one of mine on this site), I might not need outside EQ.Hopefully companies will start to look at ways to differentiate their products more at some point with a few of these features. And if I may be so bold… tone controls and variable loudness. I know many will use EQ from the source such as Roon, but once you start adding other sources it has to be in the hardware.
But a processor loop (which these have) solves the issue of adding outside processing to anything that goes through the preamp. My system uses a pair of these preamps.
