Vibration Source?

I just played Goodbye by Steve Earle. Listening to the bass, from my right speaker I’m hearing a odd harmonic distortion from the repeated plucked 1/4 notes.  Like a fuzzy articulation to the notes instead of a clean attack and decay. Seems like this indicates a recording anomaly. 

That is a nice system with good resolution.
Could very well be anomalies in the recordings.
If you do get a small sample list together with time stamps some can check their own copies and see if it exists on the recording.  I've had a few GRP and Concord Jazz recordings with brief distortions in them.  

     Thanks for the responses so far. I'll try to come with a list of songs that I notice the problem on. One I can think of off the top of my head is Steve Earl's "Goodbye" from the album Train a Comin'. It sounds like a buzz is coming from the right speaker in the midrange that is associated with the acoustic bass. If any of you play guitar or bass, think of an unwanted rattle or amp noise coming from the cabinet that the amplifier drives.
     I guess it might help some of you if I tell you what my system is. I consider it to be pretty revealing, but I haven't heard the "super systems," so maybe it's not. The room is large: 26' wide x 15' deep with a ceiling that is 14' on the sides and 18' in the middle. The speakers are along the long axis, 2.5' from the back wall. They are 8' apart and the listener position is 10' back.

     CD player:  Krell KPS 20i.
     DAC:          Audio Research DAC 3 (I just started playing with tubes.)
     Preamp:     Krell KRC HR.
     Amp:          Krell KSA 200s.
     Speakers:  Thiel CS 7.
     Cables:      All cable is Transparent Audio Ultra mm2. (except the                               digital cable.)

     The speakers are 4 ohm nominal, so the amp runs at 400w per channel. The speakers could ideally use even more power, but that's a very minor issue.

Oh.. I just had a thought. Try listening with headphones. If you still hear it then it's on the recording.

I know what you mean. Christian McBride - Gettin' To It, the last track called Night Train. You can clearly hear something resonating in the left channel. It's coming from the recording. There are other examples, but this one stands out the most.

If I put the same CD in my stock car system, it comes across as low level noise, not vibrations.

This is what gets me. So there’s some sound that is definitely there on the CD, you can hear it in the car, but it sounds different at home.

This I believe is what we call situation normal.

Main thing I want to know is what is the exact nature of this "noise"? Is it ringing? Rattling? Clanging? Scraping? You call it noise in the car and describe it almost as if its steady white noise, but in the home the same sound you call it vibrations? If its associated only with certain instruments and frequencies then its a distortion of some kind and the question is, what?

Really I do not think any one here understands what it is that you are talking regarding.

Tell us what the track is so we can see if we hear the same thing you describe.

Do I need to hire someone with "golden ears" to come by and tell me what the problem is?

yes you do but you live too far away for me to visit. 

it could be your ears or just bad speakers. Most speakers are bad. 

Just curious if the “vibration” through the speakers is your system trying to resolve some detail on certain recordings and being unable to unveil the detail due to some system deficiency. When you said the same passage comes across as just “noise” on your car stereo that also made me think that the system is falling down, not necessarily the recording. 

I don’t know what CD player you are using or what preamp, amp or integrated amp or what interconnects you are using but my gut tells me that they could play a role. 

Can you take the noisy recording to your local brick & mortar audio dealer and ask to audition that same track on some premium gear? Then you would have some points of comparison. 

Could you you tell us what CD specifically and what tracks you are experiencing this? 

I listened to CD for many years over a highly veiled system - NAD 2200 amp, with a little portable SONY D5 CD player and I would enjoy the basic structure of my recordings but always knew that the undefined “vibration” that I heard on my favorite tracks was a lack of revolving power from my system components. Forgive me if I’m wrong here - this is mostly some speculation by me.

Basically, it sounds like a buzz coming from around the speakers. My first thought was that it was some part of the living room vibrating from a resonant frequency, as frequently happens in cars. Or, maybe the midrange drivers need to be replaced in the speakers. But on closer inspection it is definitely not the former. I can't pinpoint the exact source of the buzz on the speaker, so it seems as if it coming from inside the sound field, aka the recording. I've never heard anyone talk of this issue, so I'm confused. The main thing is that it could be either side of the stereo image and always comes from one specific instrument in a recording. The buzz is faint and is imperceptible during louder passages of music (on a track where it even occurs at all.) Do I need to hire someone with "golden ears" to come by and tell me what the problem is?

I, too, have found issues with recordings. On one CD, there was a distinct low frequency 'thump'. I originally thought it to be a manufacturing defect on the CD, but when playing the same album via Qobuz, I heard the exact same 'thump' at the same time on the recording.
So, I think a distinct possibility is that the original recording may have a flaw.
Perhaps if you can try a streaming app and see if the same issue occurs, then you might have your answer.

All speakers vibrate. Its how they work. Can you narrow it down a little?
