Rocky Mountain Audio Fest 2015 • Hot Product

Zesto Audio’s attractive range of tube electronics continues to expand, taking a serious step up in both ambition and quality with the new EROS 300 monoblocks. The class-A amps run six KT88s a side and deliver 150 watts from an auto-biased circuit with zero global feedback. Input can be balanced or single ended. The sound with big-band music was impressively dynamic and rhythmically tight, clear, lucid and articulate, with a natural warmth and rich tonal palette. Priced at $19,900/pair, these Zesto amps offer an interesting alternative to the rash of KT120/KT150 amps hitting the market.
