It is stylish, packs sufficient amplification power, and delivers solid high-fidelity sonic performance. ON-OFF  (Spain) September, 2019 One strength is its capability to reproduce a wide sonic palette, with depth and plenty of micro information. Parasound's power amp is able to bring out the best bass from speakers. Different kinds of music made us appreciate the unusual character of this amplification. Outstanding! Soundstage Network  July 2019 Reviewer's Choice Parasound provides great value in the Halo A 23+. I haven't heard better sound or seen higher build quality at this price. An impressive power amplifier. Stereo+ (Norway) January 2019 Together, the Parasound P 6 and A 23+ are dynamite. Pure sonic magic with brilliant dynamics, delicious midrange and impressive resolution. To get such good sound for the price of this duo seems almost unnatural. One incredibly appealing preamp-amplifier package from Parasound. Thanks for looking and happy bidding. Good luck!
