An Audiophile Goal

An Audiophile Goal.

I have been grappling with the perceived problem of listening to LPs at the same volume setting, for every LP. The original post that I addressed this problem with is here http://forum.audiogon.com/cgi-bin/fr.pl?eanlg&1179765549&openmine&zzAcoustat6&4&5#Acoustat6. It was to discuss my idea of playing back all LPs at the same volume setting regardless of type of music or recording etc. To say it was a debacle would be an understatement to say the least. The discussion did not start the way I thought it would and went quickly downhill from there. I would like to put that behind me and realize why it was so controversial and failed as a discussion. As I originally said this idea was new to me and it took such a long time to coagulate my thoughts about this and the reasons why it works. The answer is obvious now. I didn't have an audiophile goal.

I got the answer from reading the recent post about J. Gordon Holts article in Stereophile which was discussed on Audiogon. .
The reference being about an audiophile goal in one of the posts. This was my thought, myself and audiophiles in general don't have an audiophile goal (actually, I do have several but I will stick to the topic). It seems that no one can agree on a goal, its all so subjective some say, I like it loud, I like it quiet, I like a lot of bass, I like imaging and on and on. This is fine, that is why we all buy different speakers and equipment. It comes down to you can't measure music. You have to hear it, does it make your toe tap? Can you listen at a low level? Is the tweeter too bright? Is the Bass too loud? Ad nauseum. And there we go again are my toes tapping enough? What is low level listening? Is the bass loud enough for hip hop but too loud for a violin concerto?

I found myself an audiophile goal and an easy one at that, its 20-20k hz. Yeah, you like it too. Right? You buy phono cartridges, pre-amps amps etc. that are flat 20-20k hz. So my audiophile goal is to get 20-20k hz flat (as possible). I said I needed a goal! I know there is more to it than that, but undeniably it is a goal. Now if I go with a test reference of 83db at 1000hz from my test LP this will be an excellent level for dynamics, noise levels and acuteness of hearing. All that is required is 1000hz at 83db from the test LP and all other freq matching this level, So 10,000hz and 5,000hz along with 500,100, 80, 50 and 30hz with all of the freq in between at the specified level of 83db will all be played back off of the test LP at the same level or as close as possible as can be obtained within a systems speakers and equipment and rooms limitations. Find this level and you leave your volume control set to this position for every LP you play. Pretty simple actually.

The original idea came to me slowly over the last three to four years, though I struggled with the quandary for as long as I can remember and I have yet to hear anyone say, sure you don't do that? I thought we all did. All because I didn't have an audiophile goal. Now I find out that perhaps even J. Gordon Holt may not have an audiophile goal, even one as simple as this. The best thing is now I get to listen to all of my LPs at the same gain setting with its attendant qualities of dynamics, constant noise levels, unchanging freq response and a host of other benefits which come along for the ride.

I knew it was wrong to be changing volume levels and bass levels for different LPs. Jumping up in the middle of a song to hear the bass drums or turning it down for a quiet violin solo and doing the same for complete albums. It was insane, I always felt like I was in junior high school cranking it up for the cool parts. But every one does it, so did I. I was missing that audiophile goal.

I enjoy listening to my Lps, many of which I still have from my early high school days and everything in between which amounts to about 2500 quality LPs. As a now confirmed audiophile, now that I have a realistic and perhaps more importantly a measurable goal, I could start figuring out which albums sound good and which do not. It was easy, every LP is played back at the same gain level (volume control setting if you will) and guess what you hear? Every Lp for what it actually sounds like.

Another benefit is that every system you hear is played back to the same standard from the same test LP, perhaps it could even be used at audio shows where every room is played back at this reference setting. If you choose not to listen at the standard then it is stated at the door that reference setting is either higher or lower than the reference. This way if you choose not to abuse your hearing in a room that is 6db above the reference standard you are warned before entering.

And all of this because J Gordon Holt didn't have an audiophile goal.

If you can listen to one Lp at a certain level whether it be a high or low level why can't you listen to any other record at that level?

Just a few thoughts.
Thanks,
Bob

Opalchip or others, please explain to me why you would change the volume level for different LPs, whether it be up or down, and what this can accomplish.

This has already been discussed several times but it is apparently not registering.

Look at the basic design of an LP. It is a piece of plastic with a modulated groove pressed into it. Due to various design parameters (which include characteristics of stylus size and shape on the playback cartridge) there is a maximum modulated level that can be pressed into a record.

If a musical piece has a lot of low bass present, this requires wider grooves than music that doesn't have as much bass. As a practical matter, if you want the full volume on music with a lot of bass content, you are limited to about 15 minutes on each side of the record.

Unfortunately, not all musical pieces are conveniently cut into 15 minute segments. If you have a symphonic piece that is 50 minutes long (25 minutes a side), but still has lots of kettle drum action, the record stamping plant must press the record with a lower modulation level in the grooves to get it all on the record. That is just a fact of life.

With your system of finding a single spot where you permanently park your volume knob setting, this means that some records are going to be played louder than they should and some records will be softer. That long symphony (or Led Zeppelin) record you have will be played at too low a volume. However, a short record (say our harpsichord) would end up being played too loudly under your system.

You might be better off buying yourself an inexpensive sound level meter. Take it to some live concerts and check the actual volume you are hearing where you sit. Then go home, and use the meter to set your stereo to that volume. You'll be far closer to getting an authentic experience with this method than the one you're trying to use.

Hello, Trust me it is registering what you are saying, and conversely you are not hearing what I am saying. LPs are limited to only so much energy available to them, as an example, and it is up to the engineer to get the most out of this. I can only provide the vehicle for the LP to reveal itself as either a "good" or "bad" recording of music or perhaps its sonics are somewhere inbetween. If it is not there, there is nothing you can do to fix this, and all other problems with LPs including, but not limited to, previous groove damage, lack of dynamics, rumble, pops/clicks, noisy vinyl, bad pressings, LPs that are recorded too loud or too low etc... you tell me what changing volume levels does to improve the record? Or what you can do to improve them in general that would not adversly affect the sonics of a well recorded LP? Perhaps even why you want to say a record with those problems, if they are serious enough, are worth listening to?

Thats just it, most LPs suck, many are OK, a number are good and few are great. Or are you tring to tell me that all LPs are great? If you manipulate them enough... Its not my job to correct what some lousy engineer, bad pressing or poor condition LP has to offer by manipulating my system so no LP sounds good. I do have an slp meter.

Now about the audiophile goal..

...you tell me what changing volume levels does to improve the record?

Changing your volume knob's setting is a way to bring that recording closer to the actual experience of the live event.

Example 1: Our 15 minute per side harpsichord recording. It is recorded at full available groove modulation due to the short length of the musical composition and the lack of bass inherent in the instrument. At a live performance, let's say the average perceived volume at my seat is 72 dB.

I play the record with a preset volume control. Due to the LP I am presented with, I have a harpsichord blasting away at 90 dB. That hardly strikes me as desirable if one is trying to closely recreate the live experience.

Example 2: We have a LP of a 50 minute Mahler symphony. At the concert, the average SPL at my seat is 90 dB. Due to the inherent limitations of the LP format, the LP was pressed with lower groove modulations. (This is NOT because the engineer did a "lousy" job. The physics of LP production required that lower level.) When I play back this record on my fixed-volume level stereo, I get a 75 dB playback level. That is substantially softer than what I heard live.

The solution for the vast majority of music listeners is to turn down the volume somewhat when listening to the harpsichord recording and to turn it up when listening to the full symphony.

The quality of the record is just what it is. There is nothing we can do to "improve" that recording once it has left the pressing plant. However, one variable we do have control over is adjusting the playback volume to match that of a realistic concert. If you choose to listen to loud music at a low volume and soft music at a loud volume, that is certainly your prerogative. Of course, there are certainly times where the volume setting will be a good match for your LP. However, to not play a particular record at all, or to listen to it at an inappropriate volume simply because of a volume mismatch strikes me as unnecessarily robbing yourself of otherwise enjoyable experience.

In my opinion there is nothing magic about a particular volume setting on a preamp since the output volume of source material varies so widely. (This is also true of CD, open reel, FM broadcast and other music sources as well as LPs.) Having music play at an appropriate volume for the piece in question is important to me (and many others I suspect) and it is something over which I have control. It seems you choose otherwise, but that is certainly your option. Just remember to enjoy your music.

Great thread, BTW.

I change the volume on each LP to the level that makes me happy at the time. Sometimes it's at a volume that I imagine for a live performance, at other times is softer than that and at other times it's louder than the probable performance level. My objective is to enjoy the music.

You obviously love music, given the size of your record collection. I don't think that most people collect that many records without loving music, so I'm going to assume that music attracted you to audio. I also suspect that you're a "numbers guy" of some sort.

I'm a "numbers guy" and make my living helping banks hedge certain interest rate risk and mortgage prepayment risk. I've been a CPA since 1970. Fixating on numbers is very common within corporate environments and can lead to unhealthy, unintended consequences. I see things go astray all the time, particularly when you start mixing numbers and egos. Most of us acknowledge that egos are not always rational and logical. It took me a long time to learn that numbers are not always rational and logical. Hopefully you'll trust me on that. Once I learned that, I started spending a lot more of my time trying to get people to focus on the "right number".

Just because something can be measured doesn't make it a appropriate or valuable goal. For instance, if you mainly listened to acoustic jazz, then a speaker that extended to 20hz rather than rolling off at 30Hz wouldn't increase your enjoyment of the music.

Another system might be flat up to 20kHz but then use nonlinear filters to make a hard response cut at 30kHz. Such a system might fatigue you, where a system that down 3dB at 16kHz, but rolls off smoothly up to 60kHz and higher might sound really smooth and be listenable for hours on end.

Why would you focus on volume, based on a reference that will likely not match your actual library of records? You might focus on such a goal because your hearing is already impaired and you want to avoid further impairment. That's a good goal and it'll extend your ability to enjoy music for a longer number of years. However, if the dynamics on a particular record or CD far exceed those on your reference, then you're hearing might still be at risk. Rather than using the reference, you'd be better off having a quick response SPL meter going all the time, that could flash red if you approached your danger threshold.

With all due respect, I think that you should focus on your own musical enjoyment. Measurements can never "validate" your system, since someone can always argue with what measurement is more important. OTOH, no one can say to you, "you couldn't enjoy that because the sound level wasn't realistic". You can answer back that "I enjoyed that thoroughly and played it at a level that was very pleasing for me at the time. Tomorrow I may play it louder or softer, but my goal will be to enjoy it, not match some perceived goal."

Just my two-cents...

....audio as a mood enhancer for mating. Now we're talkin'!

I agree in principal with the Hardesty camp. But it is just a starting place, ESPECIALLY when it comes to vinyl. You have to realize that in the golden age of LP's, nobody cared about Flat or Phase correctness. The recording signal probably went through 3 or 4 processors before landing on the Master tape, and not only that, but different tracks of the performance went through different processors at different settings. The mixing and mastering engineer used at a minimum - a peak limiter, compression, and an equalizer - in addition to whatever went on in the mixing board. If a voice was involved, they probably added a small amount of reverb to that track. And what's more, little attention was paid to "absolute phase" of each of these boxes. The end result that went onto the LP was actually far, far SUPERIOR to what a "Flat" recording of the studio performance would sound like. (In addition - and it's not a minor consideration - everyone's hearing is different. Your ears do not have a remotely flat frequency response.)

SO... if one can accept these facts:

One can also accept that a "flat" playback in your room is:
1. Not necessarily the best sounding - for, one, because your room is not and never will be, flat.
2. Flat what? - there is ZERO "flat" information on an lp to begin with. If you adjust the output of your system so that it sounds "better" it does not mean you are introducing coloration or distortion.

Should you NOT wear eyeglasses, in order to keep your vision "flat"? If you don't wear glasses is your vision more "honest"?

Now, I agree with Hardesty that "Flat, Time and Phase Correct" is a worthy goal and test of the ability of playback EQUIPMENT. But that does not mean that you want to use it "Flat". (And also, none of "Flat, Time and Phase Correct" is affected in the least by the volume control.)

My "audiophile goal" is simply to enjoy myself the most I can. If something sounds better to me, I enjoy myself more. This was the goal of the recording artist and mastering engineer in the first place. If an lp sounds better at one volume setting than on another, that IS the right setting. How do I decide if one lp is better than another IMO - I compare them both sounding their best.

If I find a piece of equipment that makes ALL my lp's sound better than before - that is a better piece of equipment. Simple.
