Hey audiophiles, I’m seeking advice on the compatibility of my Behringer HA 400 headphone amp, which has an output impedance of approximately 80Ω and a max output level of around 40mW in 100Ω, with my DT 990 Pro headphones that have an impedance of 250Ω. I’m concerned about potential damage – can anyone shed light on whether this setup is safe to use or if it poses a risk to my headphones? Thanks in advance for your expertise!
