I've used the HA8000 V2 in a studio setting. It seemed clean enough for the musicians recording. It didn't have any obvious problems the few times I've used it. The phones I had were pretty easy loads as phones go.
Don't know what use you have in mind. Might want to look at the P16 gear. That is really for musicians to get multiple feeds and be able to mix the feeds to their wishes while recording. Maybe the bass guitar player wants to hear mostly the drummer to keep time, and maybe the vocalist wants to hear a piano for hitting the notes, and other players other things. They get to mix them for themselves from a common feed.
