Phono. Reference. – That's Nagra's HD Phono, an all-tube singing and dancing twin-chassis affair with embedded resonance control. The outboard power supply is based on a massive supercap bank to provide virtual battery power with faster charges and higher current load. Remote-controlled load adjustments span 10-390Ω. The 26dB step-up transformers with cobalt cores and multi-week cryo treatment are wound on site and by hand. The tube complement consists of 4 EF806S and 2 E88CC. Their gain is adjustable from 30.5-42.4dB. Compensation curves include RIAA, Teldec, NAB 100 µS, Victor Europe and Victor USA. There are two MC and one 1 MM input on RCA. Those can be run in stereo or mono.
