Dolby Atmos - is it for Audiophiles?


A friend asked me over to his house this morning to audition Dolby Atmos on his pretty good 2 channel system.

Apparently - Apple are going to convert their entire streaming library to Atmos (please don’t shoot the messenger) and another well known streaming service is going to adopt it also.

Since this is my first exposure to Dolby Atmos, I came away a little confused

From the brief audition I experienced...
  • some tracks presented very well - better clarity, separation and dynamics with larger more articulate image
  • other tracks were less impressive, especially the really old tracks
  • some classical tracks sounded quite shrill and harsh
  • and one of the more recently recorded tracks did not sound too much different from the regular stereo version - but then it was Taylor Swift - again, don’t shoot the messenger:-)
Is this really meant for two channel systems?
  • it seems it may be targeting Airpod users - as opposed to 2-channel systems that use speakers
  • from the description (i.e. diagrammatically ) it looks like surround sound for Airpods.
  • does it work with existing surround sound systems?
  • it seems it only works with Atmos enabled devices - how long before my Node 2i streamer becomes obsolete?
I must admit - when it worked well it was quite impressive, but that was not even 50% of the time, so it seems there is work to be done.
  • violins sometimes sound quite harsh
  • cellos sometimes sounded very "thin" - poor bottom end and poor timbre
  • some orchestras sounded very unnatural in the top end and less bottom end than normal

If you have first hand experience with Atmos, please share your thoughts/insights with the rest of us

Many Thanks - Steve

See Mike, even you think the theater folks are second class citizens :-)
Your 2 way system is not pure analog as I do believe you have described playing CDs and digital files. 
+1, mikelavigne

For me, it’s comes down to the implementation. When you do it right, be it 2-ch audio or home theater; the outcome can be other worldly. The biggest problem I’ve seen with most systems, the room. Most rooms are not even acoustically treated or optimized for 2-ch or home theater sound.

not sure how you can make that case. having a digital source is a different thing than adding dsp to your signal path. heck, i have plenty of Lp’s that i like/love that were originally mastered digitally. i’m into music not dogma. sure; my pure analog media is my top of the heap......but i’m not limited to that. and have never claimed different.

and assuming your room is properly tuned, digital sources benefit as much from a pure analog signal path as analog sources. garbage in <-> garbage out. can some challenging rooms benefit from dsp with 2 channel? i would assume so but not experienced that personally.

if you look at my digital source, it’s bit perfect.....not upsampled or further manipulated. my guiding perspective is that i prefer to hear my music with media as close as possible to how it was recorded......in the native format. whether digital, vinyl or tape.

as far as Home Theater and the concept of ’second class’, i think that is a bad term to use. it infers some sort of negative to movies. for me movies are simply a different passtime than 2 channel music. i just bought a $17k Home Theater surround processor (Trinnov Altitude 16). i assure you my wife thinks i like my Home Theater too much. :-) many people combine 2-channel and movies. and i have a separate place upstairs in my barn where i watch sports, a rec room/game room. but i don’t view that as second class either. i like all these places to enjoy media that are each optimized for the media i use there. obviously i am most involved with my 2-channel. but i’m not feeling ’second class’ watching movies or sports.


Atmos Music is pretty cool, im not gonna lie. Atmos for movies is the bomb.

HT for me started in 1987. 34 years later i have a 7.1.4 system that make me crack up its so much fun to watch movies, the Atmos movies w/HDR (im still 1080p) are a dream compared to 480i of years ago.

fun is where its at, peace !
