Parasound A23+

The new A23+ has upgraded internal gold on gold audio connections (cleaner signal path and more reliable.), a new larger main power transformer (10-15% larger), tweaked input circuits for improved crosstalk specs and in conjunction with the larger transformer - an improved power supply for lower distortion at full power. From - 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."
