After waiting 12 months for a Decware Zen 25th Anniversary amp, and at least another 6 months wait time left, and my 12 month old Willsenton R8 red-plating on me after only 10 months of use (with upgraded Psvane EL34's) I decided to put my order in for a pair of AtmaSphere Class D's today. I LOVE tubes, I love how they sound, how they look, and the history and science behind them is fascinating to me. I just don't like living with something that takes 30-60 minutes to warm up before it sounds it's best, how I have to manually bias them a couple times a month, how their sound is always slowly degrading over time and must be replaced every few years, how dangerous it is to accidentally leave them on, etc., etc. I may eat my words and go back to tubes when the Decware finally arrives, but for now I'm ready for a change. After breakin I'll share my listening impressions with you all.
