Noise...

I’m sure this has been asked before but I’ve noticed a “white noise” when I play records that have a lot of space in the recording. For example a solo violin record of Heifetz playing the Bach Sonatas and Partitas for unaccompanied violin has a lot of this “white noise”. My current setup is a Yamaha CR-820 receiver, Yamaha YP-211 turntable, and Dynaco A-25 speakers. So I listened to the same recording from my phone and this noise was minimal so I assume it’s the turntable making noise and the fix would be to upgrade to a heavier and more robust machine?

i have this same thing going on with my tuner,it will be interesting to watch
you have some nice gear so im guessing it should not do that , but we will find out soon im sure :lurk:
 
A lot of classical tends to be recorded at low levels, so the signal to noise ratio can be less than great. Tape is good, but also subject to hiss. Bottom line is if you have the volume up, you'll likely hear some hiss. A surprising amount can be eliminated with digital processing. In days past, you could get a variable bandwidth filter that reacted to level. During the quiet parts, it would cut the HF response so less hiss. When the volume came up, the bandwidth would open up for full response. I built one from a magazine article decades ago and it worked very well. You might change cartridges or other things, but I think it may be the nature of the program material.

Please explain this. What source? How is the phone connected to the system? Also, was it the "same" recording, or maybe a remastered version?

I have an RCA going into the Aux in, and on the other end it has an 1/8 jack that I plug into the headphones jack on my iPhone. Plays wonderfully, however I like listening to the vinyl version better as its more... lifelike other than the noise. And yes, it’s the same recording.

So I turned on the high and low filters on my receiver this morning and that seemed to cut out some of the noise.
 
Maybe a dynamic range expander would help?

I consider my system good and have had reasonably good gear for decades. The main program source has always been vinyl records and I consider some detectable noise as the nature of the beast.

What is the source of the iPhone version? Streaming music service or iTunes/Apple music (I'm not up to date on "Apple speak" these days) download? What is the quality of the file?
 
A new record of excellent quality should be subjectively noise-free, as quiet as a CD. If you have other records that sound that way, your issue is with the particular recording. Otherwise, system improvements should be possible, from cleaning the stylus, to new, expensive everything.
 
Have to agree with sqlsavior.....I’ve noticed that “white noise” on some albums and not at all on others, and there are many examples of this in my collection, which isn’t huge by any standards.
 
There are many kinds of noise. Is it a hiss, a hum or static type? Maybe its your set-up and you hear it during quiet passages. It could be insufficient gain on the phono preamp board for your particular cartridge. What is the cartridge?
 
Noise is inherent in all electronics but the signal-to-noise ratio can be over 100dB so can be effectively inaudible. Phonostages are more problematic than many other devices and noise is a lot more likely to be an issue than when using other sources. However, with a 5mV mm cartridge the noise should be well below vinyl surface noise.
Are you sure the noise isn't on the recording? Microphones and tape recorders aren't noise-free and some older recordings do have audible noise on them. It should be easy enough to determine whether the noise is on the recording or in the phonostage by simply lifting the stylus off the record during a noisy part.
