My PC-Ultra will be in this week and I’m thinkin’ ahead. If I tweak any room spikes with this CD, will this setup apply equally to analog Hi-Res (SACD/DVD-A) audio? I already have Chesky’s Ultimate DVD Surround 5.1 setup Disc. It does have a low freq sweep, but it doesn’t display the current frequency being played. Do they make a SACD or DVD-A disc which does this? Or, should I even worry about this?
