Today is a remarkable day in my audio hobby realm - I received a new pair of Atmosphere Class D monoblocks, sent with a care. I plugged in them a few hours before I started to audition them. During the first few minutes of auditioning, my initial impression was the presence of solid low and mid-low frequencies, perception of body and space and lack of mid-high and high freqencies. The latter issue somehow disappeared relatively soon. The amplifier is in its first 2 hours of break in now. I'm already enjoying the sound and I feel that it will get gradually better. I think there is a lot of more to explore with these monoblocks.
I will carry out a more substantial analysis, also comparing the amplifier with a few other ones that I'm using after I return from my trip. I hope this will happen in about 3-4 weeks. Stay tuned.
