What is wrong with negative feedback?

Acoustat6, yes, sometimes I do. Most music does not demand it but some does: The Verdi Requiem, on the Soria box set (RCA) is a good example of vinyl being put the limits, and stereos too. If you play the quiet spots at the correct volume, the peaks will be at 115db."

Hi Ralph, If you listen to the Verdi Requiem at peaks to 115db (which is an impressive level for any system) then, and since we all know that rock is supposed to be even louder than an orchestra, how loud would you listen to Cream live or other "loud" rock?

Because you said, "IOW, a proper stereo should lack loudness cues, such that you can approach the same volumes in your room that the real live music could."

Then just how loud do you listen to rock on your system to approach what a live rock concert does. Its gotta be louder than a recording of Verdis Requiem!

Acoustat6, that's true. My system can play so loud that prolonged exposure can result in damage. But playing rock as loud as it is often performed has a bugaboo: most rock recordings are anything but live! Quite often the guitar amps have only 15 watts in the studio, so who is to know how loud such a recording is to be played.

I have a white-label Vertigo press of Black Sabbath's 2nd LP (Paranoid), which is an amazing recording and one that can bring most systems to their knees in a heartbeat. You play it loud, but even that one is hard to tell how loud it should be played.

I play in a rock band, and recently we did a memorial show where we were the only band on the bill that was not metal. The club we were playing in was a metal club. It was on that night that I discovered that metal bands don't play all that loud. The most powerful guitar amp we saw that night only made 25 watts. They rely on the PA.

So- how loud is that supposed to be? Rock is always tough because there is no good answer for it.

I assume you mean damage to your ears, not your system. I agree 115db is too loud as we do not want to damage our ears. Also I think that for audiophiles in general that level is very difficult to obtain. IMHO it is an unrealistic goal.

But you say, you play the Black Sabbath loud, so...

The Black Sabbath Lp you said you play loudly then is it louder than the Verdi or is the Verdi LP the LP that you play loudest? In other words, is the Verdi LP a test lp for "you want to hear loud?" then this is the loudest we go?

I am always on the lookout for LPs that streatch my systems limits, it sounds as if thats a great test LP for a systems ability to play loud. Though I dont get anywhere near 115db!

If you get the original Vertigo press there is a lot of bass and bass impact! If you try to play that anywhere near 105 or 110 db, which is justified by the material, most systems just can't do it- too much energy required. The trick it to be able to play it that loud without it **sounding** loud, IOW the only sense of volume should come from the LP itself, not the system.

Hi Atmasphere, Thanks for the advice. I have several "system busters" Lps. Certainly Daphos is high on the list along with Carmen suite on RCA and a few others that have very big dynamics.

I am curious as to your system, what does it consist of? There must be some nice OTL amps, but what else do you use? I dont believe I have ever saw references to your system speakers etc. Could you post a few pictures of your system here on the 'Gon. Although I would expect that it is constantly changing. Is this system in your house or at work?

Thanks,
Bob
