New, the REX II preamplifier retailed at roughly €23,000 equivalent, while the power amplifier was around €18,000 equivalent; this €22,000 asking price therefore depends heavily on whether it is the preamp, amplifier, or a complete pairing. Against 31 comparable used listings, the median is €18,358, with the upper quartile at €18,744, so €22,000 is ambitious rather than a bargain.
It remains a serious, desirable BAT design: fully balanced circuitry, transformer-coupled tube operation, unusually comprehensive control, and a reputation for taut, dynamic bass with excellent scale. The preamp’s two-box construction and extensive XLR connectivity are especially appealing in a high-end balanced system, while the amplifier offers 80 watts per channel and automatic biasing. At this price, confirm the exact component, tube complement, service history, and included accessories; a complete, exceptionally clean package could justify a premium, but a single unit should be negotiated toward the market median.
