No longer in a constant state of flux. Music is enjoyed using a Texas Instruments TPA3255EVM Class-D chip amp in a case with a Mean Well power supply. Several Pono players serve as DAP, DAC, & preamp delivering balanced output to Superized HIPs with Crites 120 tweeters. The balanced signal also feeds a pair of Behringer iNuke 1000dsp amps, each powering a pair of DIY Exodus Anarchy tapped horn subs. A technics TT with Denon MC cartridge is used only to rip vinyl to FLAC files. A Dual 1229 is used for 78s.
