How much LF info on LPs?

As stated above, there's no question that vinyl can go quite low, but deep bass is one of the few areas, maybe the only area, where Redbook standard CDs can actually exceed the performance of well pressed vinyl. Very deep bass on vinyl is constrained by the physical limits of the groove width. Loud music requires wide grooves. Deep bass requires wide grooves. The problem arises when you try to have loud deep bass because you'll fairly quickly run into playback tracking problems. At 60Hz this is not an issue and I believe it only becomes serious once you start to get below 40Hz. There's also the issue of running time per side of vinyl. Large amounts of deep bass cuts down the running time available per side. As a practical matter it is very rare for mastering engineers to purposely press vinyl with sub-30Hz info. Also deep bass on vinyl is always (100% of the time) mixed mono. Redbook CDs can have true channel independence down to any frequency.

Nrchy, you have a very fine system, but your speakers don't do deep bass. My comments about the merits of digital bass are from listening to a system capable of producing deep bass. Rather than talking in vague generalities, please point out a specific statement where I am in error.

To Nrchy,

My point about your speakers, which btw I also own, is that they do not produce deep bass. The Sonys fall off sharpely by mid-40Hz. Such a speaker cannot be used to make any meaningful statement about deep bass. To make myself as clear as possible, by deep bass I am referring to the octave from 20-40Hz. I respect the fact that you are reporting what you hear, which as you state has been formed by listening to more than one system, but I too have heard numerous setups and I come to an opposite conclusion than you have. Over the past few years I have had in my system digital components by Apogee, Goldmund, MSB, Sony, Sonic Frontiers and Wadia. With the exception of the Sony and Sonic Frontiers each of the digital components produced deep bass that equaled the performance of my turntable. The Goldmund and the Wadia slightly bettered the turnatable in this narrow area. You've made a broad statement that the CD medium cannot produce deep bass. My experiences tells me that you're wrong.
