RE: "IMO, solid state equipment should be run 24-7 for best sound."

Some should, other's not so much.

The only SS. audio thing I've ever had that really was significantly impacted by warm-up is my current power amp. It simply doesn't have enough feedback to fix the distortions present prior to achieving it's normal bias point. I've left it running for decades but have now stopped because I figure the electrolytics may be getting dry and I want to stretch their life. The heat generated isn't usually an issue since we heat with electricity anyway. True, it's less efficient than the heat-pump but it sounds a whole lot better...

It's rough the first 20 minutes and stops changing in an hour which, oddly enough, is when the heatsink temperature stabilizes.

As you well know all designs are a mass of trade-offs. I can live with this one although I consider it sub-optimal.

73, Rick
