About the Concentra
The Jeff Rowland Design Group Concentra 1, produced from 1996 to 2001, was the company's inaugural integrated amplifier. It integrates elements from the Synergy 2 preamplifier and Model 2 power amplifier, utilizing a power supply from the Model 2 and an output section similar to the Model 10 and Model 112. Likely employing LM3886 integrated circuits, it delivers exceptional performance beyond its rated 100 watts at 8 ohms, renowned for stirring high-end audio circles with its power, dynamics, and build quality. Features include three balanced XLR and three unbalanced RCA inputs per channel, preamp outputs in both formats, tape in/out, non-multiplexed numerical volume display (99.5 dB range, 0.5 dB resolution), dual-range volume control, and display-off option. Optional MM phono stage available. MSRP was $5600 USD; current used market prices range €2000-€2400 or $2200-$3500. No longer manufactured.
