Pass amps come with 14awg power cables. I never used a trigger despite having the amps paired with a Pass preamps (XP-12 and XP-22) that don’t feature standby mode.
Few things…,
1. The amps respond well to higher quality power cables. I used a lot of different cables from Audience F3 to Audioquest Hurricane. The Audience F3 is cheap and is a good upgrade over stock cord
2. If you plan on using single ended inputs make sure you use the XLR shorting plugs or you will have elevated noise levels.
Pass Labs make fine components. You won’t regret it.
