Distortion - is it on the recording or a system issue

There have always been some recordings on which high dynamic peaks in the high frequencies sounded slightly distorted on my system. The best example are some of Adele's vocals on the Live in Royal Albert Hall Blu Ray, and the trumpet on Abou Khalil's "Blue Camel" (e.g. 10 seconds into the opening track "Sahara"). I always assumed this was a recording issue and did not think much off it.

So a few weeks ago I inserted 6 new Shunyata Anaconda Zitron PCs into my system, and while I was originally disappointed about the impact, I now have the impression my system is really "opening up", with bigger soundstage, more detail and so on. So far so good.

However, I also have the impression the problem of the distortions I experienced has gotten a lot worse. Almost like something that was always there is now under the microscope. In fact, it has become so annoying Adele's Blue Ray has become almost unlistenable, and there are other recordings where I now seem to be having the same (albeit not as bad problem). Luckily, most CD are just fine.

When I played Abou Khalis yesterday the problem was so bad (a slight screech at peak levels - I have experienced "digital clipping" once, which was somewhat similar but worse) I finally decided to isolate the problem and see if I had a system issue.

So first, I changed from playing the ripped track from my server to playing the original CD in my CD player. Same problem, which eliminates the digital source.

Second, since the trumpet is largely mixed to the left channel, which is where the distortion is audible, I changed speaker channel. Same problem on my other speaker - not a speaker problem.

Third, I play the track trough my MSB DAC and ARC Ref 5SE preamp and Jungson Mono's. So I routed the left channel through the center channel of my system, which does D/A conversion and volume control in my Trinnov processor, and has a build in poweramp. Same problem, which rules out the poweramp, DAC and preamp.

Only thing I did not change was cabling and my P5 powerconditioners, but I'd be shocked if this had anything to do with it. The logical conclusions appears to be these distortions are on the recordings, and my system has now become so transparent with the new Shunyata cabling, it has become more audible.

Would you agree with this conclusion? Anything I am missing? Any other thoughts.

Does anyone have the Abou-Khalis recording on a highly resolving system, experiencing the same problem? If anyone wants to volunteer to play the track on their system, give me PM - may be I can get you the file through some fileshare app (never exchanged large files before, but I'm sure this can be done easily).

Anyone find Adele's blue ray distorted in the high vocal range?

I'm very puzzled by this. The Abou Khalil track is so bad, I cannot imagine a bona fide label (Enja) would publish it with this type of distortion on the mix.
 
Edorr, If you have other digital recordings of similar trumpet sounds and Adele's vocals, what do you hear? If those other recordings sound find, it seems that the problem lies in those two referenced tracks only, (as well as some others you mentioned), so it is a software issue with those recordings. You seem to have trouble shooted most other possibilities that I can think of. However, if you still hear that distortion on most similar recordings, then it could be something like a room interaction with your set up. Is your room treated at the first reflection points? How about slightly adjusting speaker toe-in or tilt? If those don't help, then I would tend to agree with your conclusion that it is the recordings. I certainly have some in my collection.

Is that a trumpet or some reed-type instrument? There is something very buzzy about the sound, like a build-up of saliva needs draining or something. It's not your system at fault anyway!

Definitely not the room. I listened right in front of the driver and the sound is coming out distorted.

It is a trumpet. Do you have access to the same track? I have some other recordings with similar issue, mostly female vocals. I also listen to Indian bamboo flute a lot and some have a slightly edge to them as well. it just appears that my system has become more unforgiving and reveal any issues on the recording.
 
The Adele album has been written about quite a bit,negatively. As suggested try adjusting your toe-in a bit. Also all cables especially good ones take 200 hours to stabalise,so it could be that. Some of these recordings that are gain boosted sound like crap,so try some early stuff and see how they sound.

Adele's "21" album is notoriously badly recorder. However, I never read about any issues with the Royal Albert Hall Blu Ray, which is why I'm surprised I have always had issues with it, even before the cable upgrade. It just got worse with the new cables.

The track I'm listening to is Sahara off this album. I reckon that's a reed instrument at the start and the trumpet doesn't take over until 1'44".

There's a thing I sometimes notice which is that combinations of wind and string instruments can sometimes sound disconcertingly like distortion. A clarinet is known to sound like a square wave i.e. odd harmonics, which also resembles analogue saturation. Sometimes when woodwind joins strings, for example, because the arranger wants to beef the sound up and make it louder, the effect can sound awfully like the onset of saturation in the recording or the system.

OK. I take your word for it. If I cannot tell the difference between reed and brass instruments, may be I should try another hobby :). anyway, the more important issue is, does it sound distorted on your system as well?
 
Edorr-What gear do you have in your system?
 
I am pretty cricital myself of Adele's albums, great talent and IMO the album sound recording is pretty average.
It sucks when dance related artists (would include Daft Punk into that background as well) are recorded better than someone who is "world known" and acclaimed as an artist, and sadly same can be said about a few other modern day acclaimed artists.
No wonder people pay a fortune to see them live :)

PS Audio P5 conditioners. CAPS 3.0 server, MSB Signature plus DAC, ARC Ref 5SE preamp, Jungson JA-200 poweramps, Evolution Acoustics MM3 speakers. All shunyata anaconda PCs and Transparent reference IC and SC.
 
Personally, I find the idea of "system opened up" and "distortion seems up" to be quite reasonable. Having said that, you want to pick what makes you happy.
 
I don't think you have a distortion problem. The higher resolution has made "noise" the issue.
