I just knocked up a quick fixed level matched 4 resistor shunt attenuator The sound stage is more balanced than the ALPS Blue, bass is more detailed and treble has stopped hiding in the background but is smoother. So I'm ready to go to a stepped attenuator that doesn't cost a fortune. Has anyone had experience with the Valab 23 Step Attenuator and how does the resistor version differ from the SMD version? EIZZ - These look really well designed and manufactured and the workmanship impresses me but do they perform as well as they look? Dale - These look neat internally but how do they sound? Thanks!
