Processing the deli­cate phono signal is one of the biggest chal­len­ges that ampli­fier desig­ners have to face. That is why the Acoustic Signa­ture Tango Refe­rence is undoub­tedly the most elabo­rate phono pre­amp­lifier we have ever made.
The reso­nance-opti­mized and anti-mag­netic chassis made of a 70 mm thick and 22 kg solid alu­minum block, makes it clear how serious we are about this phono equa­lizer. The over-dimen­sioned power supply with toroi­dal trans­former is located on a sepa­rate board to ensure an absolute current stability. Both assem­blies are mounted on a special shiel­ding steel plate to avoid any inter­ference with the phono signal.
The Tango Refe­rence uses only high quality compo­nents that are indivi­dually selec­ted. In this way, its semi-active RIAA equa­lization achie­ves extre­mely accurate values with a maxi­mum devia­tion of less than 0.1 dB from the ideal curve! The elabo­rate single-ended output stage was desig­ned in Class A to gua­ran­tee minimal distor­tion as well as low hum and noise – the basis for high-reso­lution, fasci­nating 3D-imaging and invol­ving musi­cality. With its selec­table gain and 90-steps load impe­dance confi­gu­ra­tion, the Tango Refe­rence also offers optimal mat­ching options for any high-quality MM and MC cart­ridge.
