JMTCW. I've compared the Rega Brio R with Brio 3, its immediate predecessor, side by side, over an extended period, say 50 hours. I am very familiar with the Rega family sound (having spent over 30 years in audio). The Brio R sonic character is vastly different from the Brio 3. I concur with mezzanine and others who are concerned with the Brio R displaying metallic harshness in the upper-mids and treble. I also feel its overall presentation is sterile, distant, spatially-constrained and lacking air/bloom in comparison to my references (Canary tube pre-amp, Atoll FET power amp, fed by Oppo 93 and custom DAC, powering Merlin TSM monitors, Huffman ICs and Clear Day speaker cables). In examining the Brio R's pre-amp section Rega appear to have installed an ancient TI TL072 opamp on line-level duties with what appear to be cheap Arcotronics(?) polyester 2.2uf input coupling caps. These components differ from the Brio 3 which appears to use a JRC opamp and Evox MMK input caps. These two aspects are likely to shape both amps' sonic characters significantly. I do hope Rega designers at least consider modifying the Brio R's front end for enhanced musicality. To be fair the Brio R's power amp section does a great job of delivering dynamics, grip, extension and PRaT. But this prowess cannot entirely compensate for that other perceived sonic shortcoming. Unfortunately it makes the Brio R tiresome to listen to, and does not quite fullfill its undoubted potential. YMMV. Enjoy the music!
