@kirkwallace like I said, I'm just a stranger on the web. Nobody need listen to me My bigger point is that the suggestions offered by others may not be the best solutions to exploit the OP's DAC. I think that if the op asks AI the questions I suggested, he'll be better prepared to make a good choice. Too many folks throw out a suggestion without explaining why it's the correct one for its intended use.
For example, that someone suggested the OP could do better than his current reference-level machine simply by spending $3k is nuts.
