This is an excellent amp that punches way above its pricepoint. My best friend is a tech who worked on high end hifi equipment for years — he directed me to this amp. When he opened the Onix up to take a look, he was very impressed and said from a component / build perspective it was better-made than many systems he worked on that cost 2-3x as much. Premium tubes here, 6sn7 matched vintage Sylvanias, 7025s (12ax7s) are promo new ones, NOS 6922/6dj8s, and power tubes are very nice TAD el34s. All very low hours. This is a lot of money just in tubes! In excellent, near-new condition, this amp needs nothing. If you are curious about getting into tube amps then i cannot imagine a better entry point. Located in James Bay. No trades.
