… the addition of that tub-y warmth worked magic on a voice that's already so honeyed as to border on the calorific.
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-y sound: it's an absolute knock-out, even proving itself in an uber-high-end £100k system with a £10k MC. This is a killer.
At this price point, the Tube Box DS2 simply can’t be beaten
• As the ultimate compliment in any review, I will be buying this preamp. Having compared the Tube Box DS2 to another external Phono Stage I’ve settled on the tube option as I found the overall listening experience more dynamic and musical.
