The front panel of the Antileon Evo is mostly acrylic and has six buttons. The far left button is an ON/STANDBY button that, when pressed, activates the amp and reveals a red display behind clear acrylic. This also initiates a self-check that takes approximately 15 seconds and lets you know if there are issues with the amp. The CHECK button at the far right allows you to run the self-check while in full operation. There is also a MUTE button that does exactly that — mutes the sound — which is handy when you want to change out some cables without turning the amp off. However, the remaining three buttons are the most interesting to the dedicated audiophile.
The remaining three front-panel buttons allow you to choose between three bias settings: Bias L (low), M (medium) and H (high). Bias L provides 25 wpc of class A power. This setting is fine for listening at low levels or when simply playing background music, and to my ears sounds better than the vast majority of A/B amps. I mostly used this setting to keep the Evo warm during the day so that it would be ready to play in Bias M or Bias H mode at a moment’s notice in the evening. Bias M and H were the settings I used for serious listening. Bias M delivers 50 wpc of class A power, which I use when blasting certain rock or other highly in-your-face music. Bias H delivers a sumptuous 150 wpc of class A power. I used this for most really serious listening sessions, even most rock, but especially when the music is vocal, orchestral, moody or sophisticated (I’ll expand on this below).
