Notes: Digitally-controlled analog passive EQ using Soviet-era military-grade double-triode tubes (1970s-80s) - defining feature flagged (analog tube path + full digital recall/plugin control). Manufacturer EUR price €3,300 net. USD price used here ($2,999) was the most repeated figure across dealer search results; one source also showed a new unit at $3,799 (eBay via Sweetwater) and an open-box at $2,898, so treat $2,999 as moderate-confidence street price, not a confirmed single MSRP.
