Anyone own or have heard the vintage Luxman AD8000 step up transformers? It looks like the AD8000 is the adapter wherein you mount either the 8020 (20dB gain) or the 8030 (30dB gain) transformers. Very cool system and seems to have SOT specs.
Any comparison to something like the Ortofon ST-80 or ST-90; Technics SH-305MC?
