I have the BHK 250, BHK Preamp, and Direcstream DAC. They’re excellent components and sound even better with upgraded tubes, footers, and fuses (eg. Synergistic Black fuse).
Has anyone replaced the IEC inlet on the BHK 250 or preamp? Being somewhat obsessive, I’m annoyed that some IEC inlets don’t provide a good connection. Since my recent upgrade to Furutech FI-50 NCF power connectors have made quite an improvement, I wonder if an inlet upgrade (eg. FI-09 NCF) is worthwhile.
Looking inside the BHK 250, my impression is that the upgrade requires a factory or shop visit.
