Shure SM58 connected to Pleiades (175mH:175mH) or EMIRS106A for hi pass filtering

Male voice singing softly No Surprises - Radiohead 24in from SM58, mic 30 degrees towards nose above head. After filtering connecting to the mic input of Sony TC-D5M. At the 150Hz setting EMI 106A sounded fantastic, less fat than with the Pleiades 175mH:175mH which may be better together with other instruments in a mix? But then listening again to Radiohead there seemed to be some more bass in the voice. Monitoring was with Pleiades 2N3053 class A amplifier connected to Celestion Ditton 150.
