Can you post the FR plot of your room? REW measurement software is free, it is always interesting and often revealing to see exactly what your room is doing.

What is the cause of PCM glare? Bad recording or Bad DAC? Anything banish it?

Post the FR plots of some other cartridges, just checked my XV1S which has a very flat FR but even that is .5/6 dB down from 2-10Hz.

Keith,
IME, TT do not measure very well in the low frequencies. In fact, there's no truly accurate test disc because there's no lathe which can accurately represent logsweep at very low frequencies. When measuring a TT using high performance testing gear, I've found there's a lot of tail chasing at low frequencies with vinyl. That's what made me give up on it. For a system which is otherwise accurate at low frequencies, vinyl presents way too much of a performance compromise.

Keith I thought we were discussing glare? Did you leave the k out of your 2-10Hz my friend?
That is why I use Dynavector, but not all carts are the same, you might also check the accuracy of the RIAA equalisation, they are often all over the place.
I believe it is no more than hearing digital ( flat FR ) in a system which has been optimised for vinyl.
There are plenty of bad recordings these days, compressed , limited but that is not the ffault of the medium but of the practitioner.

This is why I use Ortofon, no mushroom shaped curve and it coexists beautifully with my digital side. Solid state phono preamp so no mushy tubes on the RIAA side.
I agree if you look at the way the cutting head has to be nursed to avoid burn out etc etc, it is simply not a very accurate medium.
I am always amazed that it can sound as good as it does despite it's technical deficiencies .

My other favourite manufacturer, also each new unit sounds and measures like the previous one,not always the case with some boutique makers.
Keith.
Sorry, Dude. I don't have the time to do it. Unfortunately, I'm way too busy to fukc around with that. A lot of work, family, friends, sports, & other hobbies keep me busy. I get to listen to my system 12 hours a week to find that State of Flow and help me forget about the world. It's mind blowingly amazing every time!
I did have one knowledgeable guy measure my main system room for me a long while ago and told me it was good. I have a lot of treatment, but not so much to deaden the sound. I don't remember all the details from his exercise, but I have something like +_3 variation everywhere . Might be slightly larger variations below 80, but it's a shared living space and I honestly don't give a fig about perfection , since I really , really, really love my system.
On your end, is there a chance you can ping this Bruno P. dude, whose gear you sell, to explain what he does to take out the glare?
Caesar, the continual vinyl/digital argument is nonsensical, I am interested in achieving the highest possible sound quality irrespective of format.
Acoustically measuring your room would take ten minutes ,and could lead to the largest improvement in sound quality you have ever experienced, at minimal cost.
Or would you prefer I sell you a very expensive dac from that Bruno P dude, who I am almost certain also gives no credence whatsoever to PCM 'glare'.
Keith.
You can try, but I think you will need a PC/Mac or you could try Diracs free two week trial, you will need a microphone.

Me too, it actually seems now a bit of a chore opening my MacBook waiting the interminable time for it to open ...

Some people seem to be confusing strong treble, with distorted treble. Strong treble is what one gets in real life, from real instruments; distorted treble is what a very high percentage of audio systems deliver when they're not working correctly, and you can call that "glare" - just fiddling with a tone control is using aspirin to ease the discomfort, not solving the problem.
The essence of what I've been doing for years is to sort out a system to minimise that type of distortion coming to the party - if you do that correctly, the "glare" of a crescendo becomes the intensity, the bite of the "real thing" ... suddenly, that CD becomes really good to listen to ...

Very much so... most systems I hear portray treble so softly it's utterly unrealistic to the core. The problem is that if the parts of the stereo can't remove enough noise, then you wouldn't be able to listen to otherwise.
OK, using that defintion, what I called "glare" is really just strong treble. I'm very sensitive to distortion on crescendos, right through the spectrum. For some reason many people are largely unaffected by it, or even prefer it. For example, the 40th Anniversary remaster of Supertramp's "Crime Of The Century" was overcooked in the bass, yet few people seem to have noticed. Distortion on crescendos is actually an area where it helps to have experience with "lesser" systems where it tends to happen more often, so that the lack of it is more obvious (you don't miss what you've never experienced). I agree about live music, even though my tastes are rock/prog/metal rather than classical/jazz I still judge a system by its ability to recreate the intensity and excitement of the original performance.
Yes
It is caused by the narrow alias-band that is present between 20 and 24.1kHz. Removing this band prior to playback restores naturalness and focus
