Spkrplus, I believe they outperform the M-60. I’ve had s-30, M-60 and my MA-1. I am not sure I’d say they are Tube like. But they aren’t harsh and bright like many SS Amps.
Elangley01, No the just didn’t add some distortion and create some amps. This is a complete departure as to the way all other Class D Amps have been designed in the past. Hence how Atma-Sphere got a new Patent in the Circuit Design. I doubt the NC400 would be close to having the sonic character as these do. I’ve listened to many high end Class D. Some costing more. And these are better defiantly better. On Monday I’ll have another more expensive Class D to run side by side in my system. Just to see how much bettter the Atma-Sphere really is.
As far as “Break-in” Ralph said not a lot just a day or two. They share same components like Power Supply, Capacitors and such. Which pretty mush all need some “Break in” time. I’ve always trusted Ralph and his staff to give Honest and Straight answers. I hadn’t heard the finished product. But I know Ralph very proud of this product. As he should be. And he is the Designer. So I thought there maybe some Bias. But I think he down played these to me. These are truely an awesome amplifier. Are they as good as my MA-1’s? In some ways yes. And others ways no. Will I like them better than my MA-1. Probably not. But the MA-1’s are Basically 4 times the cost,also. And they are simply a special amplifier. IMHO… I’ll reserve comments on that for down the road while I get to compare them more. Need to get used to the Class D some. But there is no heat from the Class D. My house is super insulated. So the MA-1 do heat the room some after awhile. The tubes don’t run super hot because they aren’t driven hard. And they last forever it seems. But they do warm the room up. Hence why I got these.
