Is there really a strong interest in film photography?

[Sal Santamaura]

Yep, but now the audiophiles say that a digital dynamometer is the way to go. There are even apps for phones that do this.

The phone apps are probably OK for rpm calibration, but aren't "digital dynamometers" used to measure stylus force?

A good, pristinely clean 180-200 gram pressing played back on a reference grade turntable setup often achieves a lower noise floor. This is because digital suffers from a high amount of Quantization noise and distortion.

Digital quantization noise and distortion occur only at and around the Nyquest frequency. My hearing does not extend to 22.05kHz, so I do not hear the quantization noise and distortion on CDs. The Nyquest frequency for 96/24 digital recordings is 48kHz and for 192/24 digital recordings is 96kHz. Both are the well beyond the range of human hearing, so
quantization noise and distortion are not in play. However, I do hear the groove noise even on a pristinely clean 180-200 gram pressing played back on a reference grade turntable setup. On less expensive turntables, the groove noise is worse. Pops and ticks are a separate problem which can be addressed with a good LP cleaning machine and antistatic products.

One would use a stylus force guage to set stylus tracking force. They are inexpensive. He is an example:

Actually you do since it filters into the audible band, which is easily measured.

CD players do have anti-aliasing filters, some quite sophisticated, e.g. apodising filters, to prevent the problem you describe, but if you have convinced yourself that you can hear quantization noise and distortion on CDs, by all means continue to listen to your pristinely clean 180-200 gram pressings played back on your reference grade turntable setup. Frankly, I am a little surprised you can hear quantization noise and distortion on CDs, yet you can't hear groove noise on vinyl, but I guess everyone's hearing differs.

I am very sensitive to digital noise and distortion. Groove noise is mainly the product of mistracking and contamination. I hear it very clearly when it is present.

I think I saw one that does both. The phone app are strange in that the phone is placed on the platter and taken for a ride.

So on which system are you currently listening to music, digital or vinyl?

Sorry George. Nope. I love my vinyl but to be honest with myself a CD is clear of any noise from the CD itself.

I'm currently listening to my old record collection from the 70's on the Voice of Music console my dad bought mom in 1959. I refurbished the turntable and upgraded the cartridge a bit and had the tube amp rebuilt by a local guitar guru. Then I found a matching satellite speaker which I power with a digital amp for stereo sound. I love the sound, and the pops, hiss and hum are part of the experience. The little red light on the front of the console takes me straight back to my five-year-old self.

YES! I grew up listening to lots of shortwave on my Hallicrafters S-120 and just learned to listen through all the static and squeals. I still have two radios that have the "tuning eye" tubes. Great stuff.

And how is my better than any of you are likely to have system relevant? I can give you a hint at its caliber by telling you that I use an Accuphase amp/preamp, Micro Seiki turntable, and Acoustat speakers.

I do have a special transport and dac as well.

Gee, I just asked if you were listening to vinyl or digital. From your description, it sounds like both. I am surprised you listen to digital, given your special sensitivity to digital noise and distortion.

This thread is about stereo system humblebragging.

Well, I spent years trying different methods and equipment to achieve a tolerable state of playback of my cd's.

I restored a Fisher Price record player. It gets lots of use. My other machine is an Ion USB record player.

I like to watch audiophiles cringe.

It's a fun ride.

Back to the subject though. I'm watching cameras sell now that people would have turned their noses up at 2-3 years ago. 'Nobody wants X' 'Y brand is worthless'

And now just about anything with a shutter is selling.

But I do not look at this thread for various opinions and arguments about sound systems. Back on topic please!

Only if you can point out where to place the microphone and speakers.

There are plenty of pictures posted on hifi and instrument forums that may be able to aid you in your quest.
