Atma-Sphere Class D… Amazing

Today I picked up my Atma-Sphere Class D Amps. These aren’t broken in yet. And they are simply amazing. I’ve listen to a lot of High End Class D. Some that cost many times what Atma-Sphere Class D costs. I wasn’t a fan of any of them. But these amps are amazing. I really expected to hate them. So my expectations were low. The Details are of what I’ve never heard from any other amps. They are extremely neutral. To say the realism is is extremely good is a gross understatement. They are so transparent it’s scary. These amps just grab you and suck you into the music. After I live with them some and get them broken in. And do some comparisons to some other high end Amps Solid State, Tubes and Class D’s, also in other systems I’ll do a more comprehensive review. But for now, these are simply amazing amps.. Congrats to Ralph and his team. You guys nailed on these.

Good to know this Ralph. But it is not an option when you have a tube preamp - right?

@milpai That probably depends on the tube preamp. I don't leave any of my equipment on all the time, except my DAC.

I leave the Atma Class D's on and shut off everything else.

Luckily, the Belles preamp turns on with the Mute switch engaged, so no thumps.

Though I wonder if there is a way to mute a tube preamp when turning it on...

My tube-pre mutes for ~90 seconds on power up and mutes, with a few seconds of delay, before powering off.

The whole “leave it on” stuff is something I hear about all the time, but have never experienced as a sonic bloom of rainbows and unicorns.

 

But I do leave on the Ayiama and NAD gear that is doing HT… mostly because it is easier for the Haus-boss.

And I would have no issue leaving on the Atmasphere Class-D for convenience sake, but I would not be doing it for sonic benefits.

After waiting 12 months for a Decware Zen 25th Anniversary amp, and at least another 6 months wait time left, and my 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.
