If you want the latest HDR/HDMI format support:
* Marantz SR6013 for $1500.
Even though it uses AKM 4458’s on all channels, if you wish to use a different DAC for stereo music, get the Bluesound Node 2i for $500 as the streamer. For the DAC, your current one is good, but it’s using the ESS 9018, whereas the 9038 is the current gen, and the Topping D50 is $250 and uses dual 9038’s and measures excellent (jitter reduction better than -125dBFS, >20Bit while maintaining +/-0.1dB of linearity, THD below -105dBFS, IMD below -55dB (-105dB at 0dBFs), etc.).
The Marantz can also be run in bi-amp mode if you wish for more power. The quality of the wattage is also pretty high (0.003% THD from 10W to 90W, better than +/-0.25dB linearity with analog inputs, better than -0.3dB with digital inouts, crosstalk better than -75dBFS at max output, SNR >110dBA, etc.)
