Analog Instruments Apparition with Sigiwan upgrades. I don't remember which ones. This arm has been rewired with super fine and rare Nippon 6 nines OFC copper tonearm wire. The result was significant in improvement. Captive 5 pin din socket now accepts standard tonearm cable which is not included. The cartridge was mounted for demonstration and is also not included. A top performing arm which has very little competition in its price point. Thinning out my collection.
