I’ve listened to MBL 101E with a variety of components: Jeff Rowland 725 amps, McIntosh amps, and now they’re connected to PS Audio BHK 300 mono-amps. The MBL preamp was used every time I heard them.. All cables are Wireworld Platinum Series 7. The 101E’s are very detailed, open, great imaging and tonality. They can sound too detailed, almost bright at times.
