Thanks for chiming in, Freddy Yes, fader resolution, I did allude to that That's a very good reason to keep the levels lower since the fader's resolution is best around unity gain. Nice interface,BTW. That's beautiful meter resolution So what do you make of the level argument as it relates to operations ITB. Does a plug in really not work/sound properly with those (supposedly) hot levels? I'm sometimes wondering if the opposite is true. -15dBfs with a -18dBfs reference at +4dBu equals +7dBu peaklevel. Does a piece of classic gear really sound best with peak levels that "low" ?
