Yes, electronics are often expensive in Europe given the sales tax situation.
I'm not a big believer in amplifier and DACs, unless we're talking about tube rolling ;p I think most amps are powerful enough for headphones, unless we're talking about electrostatics.
ZH1ES has some nice features that I think makes it future proof: ultra-high sample rate PCM & DSD, DSEE HX, FPGA solution and Frame-beam construction.
Some may say all DSPs are bad, but my UDA-1 does wonders with Youtube videos and other compressed formats, so I welcome the addition of DSEE HX to ToTL DAC/Amp models. Unlike ClearAudio, it doesn't create drastic sound signature changes, and DSEE is hardware based.
