Here the verdict is a fait accompli as I have been using the Tube Box DS2 for over a year as my budget reference phono amp. It was enough that it handles two decks, has two outputs and adjustable loading to match any cartridge likely to cross my path. Above all, though, is the sublime valve- sound: it’s an absolute knock-out,even proving itself in an uberhigh-end £100k system with a £10k MC. This is a killer.Ken Kessler Hifi News
