Some weeks ago I showed the line output / volume control transformers with silver windings on finemet cores which Tribute made for me. Now a line stage which uses them is finished.
The circuit is the same as that of previous 10Y line stages. The only difference is the silver wire and nano crystalline core material of the OPTVCs. And a different color scheme, black and white with silver metal plates.
The upgrade of the OPTVCs is well worth it. They bring a clearly audible advance in sound quality. The silver wire seems to have the same effect as in a previously built silver line stage. The finemet cores add yet another level of refinement to the sound quality which is achieved by the silver wire.
The different sound layers of a recording fall into a new perspective. Separation of background vocals and instruments becomes more audible, without the sound image falling apart, it stays well integrated. Altough I usually do not care too much about sound stage, this preamp brings better focus of instruments and voices which is beautiful.
Silver wire and finemet cores are an interesting new endeavour which I will explore further. Stay tuned!
