{"product_id":"fezz-audio-ovo-headphone-amplifier","title":"Fezz Audio OVO Headphone Amplifier","description":"\u003cp\u003eOVO is the single-ended counterpart to the Omega Lupi — a Class A tube headphone amplifier on EL84 tubes, with both balanced and unbalanced headphone connection. Where the Omega Lupi is push-pull and built for drive, OVO pursues the directness and tone purity of a single-ended design, applied to headphone listening. It is the top of the Fezz Audio headphone line, for the listener who wants the single-ended character in the most intimate form audio takes.\u003c\/p\u003e\u003cp\u003eA single-ended Class A circuit is the simplest, most transparent way to use a tube — the shortest signal path, the quality the Fezz 300B integrateds chase, here scaled to headphones. OVO runs EL84 tubes in that single-ended configuration and offers both balanced and unbalanced headphone outputs, so it suits modern balanced headphone cables as well as conventional ones. Its transformers are toroidal designs wound in-house by Fezz, drawing on the family's three decades of transformer engineering through its sister company, Toroidy.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSingle-Ended Class A.\u003c\/strong\u003e EL84 tubes in a single-ended Class A circuit — the most direct, transparent use of a tube, the single-ended character applied to headphone listening.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBalanced and Unbalanced Output.\u003c\/strong\u003e OVO provides both balanced and unbalanced headphone connection, ready for modern balanced headphone cables and conventional ones alike.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAuto-Bias.\u003c\/strong\u003e OVO sets and holds the bias on its output tubes automatically.
