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.

@tinear123 you mentioned these Atma-sphere's class D being in the realm of PS Audio m700. I've been considering the M1200's with a tube input. Have you heard these? Would you care to explain how the same or different the Atma-sphere may be vs the PS Audio monoblocks? 

@tinear123,

When you listed your system, it looked to me that the Atma-Sphere amps would be the best fit to replace your Crown-XLi-1500 bass amp. The Reference Compact cabinets in my experience respond well to the best amplification possible.

(I have a pair of BD-Design Reference Compact bass cabinets I built years ago -- they are in storage).

Although perhaps your configuration is such that it would be hard to replace the Crown for some reason? If not, you may want to try a swap.

Cheers.

Unfortunately, no I have not tried the PS M-1200 it would be severe overkill for my horn application as was the M-700. That being said I did hear it back to back with the PS-BHK300 on Wilson Sasha DAW and my preference was the M-1200. If you need the power might be a solution especially with the tube rollable input stage.

@williamdc

Funny you mentioned this as it was on my mind for this morning... I will say the cheapo Crown did spank the PS M-700 previously leaving me shocked. I was so sure the PS would crush the Crown that I dug out the Crown box from the attic before installing the M-700s... then 3 days later took the Crown box back to the attic and sold the M-700s.

 

 

I don't think it is luck to have an amp that measures well and sounds good. I think it is the goal of many skilled engineers/designers. There are plenty of amps that measure very well and are very successful in the marketplace. There are also many that measure poorly in comparison, and yet they too find their supporters. If one didn't know better one might be tempted to believe that people's tastes vary quite significantly and that "good" and "not good" perceptions are relative to the individual, not the gear.

@kuribo my attempt at sarcasm or sardonicism may have been too well disguised.

 

One last comment then I’ll sign off. I have not been on AGON for about a year and since I was interested in the new Atma-Sphere Class-D I thought I would check to see what others were saying and stumbled on to this thread at page-2. When I secured a home demo opportunity, I thought I would give input to add to the community. That being said, the fiasco that this thread has become with the measurement vs perception "comments / pissing match" has reaffirmed my worst fears of what AGON has devolved into. Worse that small children. I just cannot understand why stating your position and one possible retort with civility is not possible by some. You may be having fun being the bully of the playground, and smarter than everyone else, and while you may think you are teaching others, you are in fact disenfranchising those that are starting their audio journey and corrupting the social space this platform can enable and frankly killing the hobby.

Done & out for another 6 to 9 months.
