Pass labs xa30.8 vs Krell evo 402e

We've used a Pass XA-30.5 with our Wilson Sasha speakers for over a year before purchasing a pair of XA-200.5's.
If your system has far / veiled vocal reproduction issues, it's not the amplifier.
The 30.5 amplifier is one of the most natural sounding amplifiers I've ever heard. This compared to live music and voices.
Sorry - I have no experience with Krell evo 402e.

Thank you! Maybe it's my system's setup. What DAC are you using?

you need to post all your equipment, including speakers so we can help troubleshoot. The vocals on that amp (XA30.5) should be anything but veiled.
