Using an SPL meter

How would one use an SPL meter like the digital one put out by Radio Shack? For example, what test CD is best for plotting on a spreadsheet and so forth? What would be the x and y axis of a line graph?

Also, the ATI analog meter featured in Stereophile has the same specs as the RS digital meter but costs $20 more than the RS model. An analog meter seems confusing when the digital will just maintain a memory of measurement and averages. It just seems like something that would keep me busy with my bi-polar disorder and all.

New Tubes, New Noise

Forums

Hi All,
I just received new JJ EL34 tubes for my amplifier and now when I turn it on I receive a FIZZING type noise through my left channel. The Volume does not effect the sound and I only have about 14 hours into breakin.
The sound comes about 10 seconds after I power up and goes away completely after about 20 seconds later.

Thoughts?

Thanks,
Don L

Forum party at the Hi-Fi show in L.A.?

Aloha,

My buddy, Big Mike, and I have received final clearance from the spouses for next week's High End show.

We're approved for non-injectable substance abuse - predominantly liquid products of fermentation - and staying up until all hours without parental responsibilities.

So, looking for some like minded fellow forumites for having some of these forum discussions/arguments/expoundifications in person.

I'm getting excited about the Show. You know what <a href="http://www.he2006.com/">Show</a&gt; I'm talking about. I have this good feeling that I'm going to rock it. Hmm, thinking back, I've actually had this good feeling before every show I've attended. Then, I get there, I shake somebody's hand, and I get sick. Disappointed and fatigued, I get left in the dust. <a href="http://blog.stereophile.com/stephenmejias/010606neer/">The guys call me names.</a> But, that's not going to happen this time. No, it isn't. Today is a new day.

When I was a corporate speechwriter, I wrote a speech for the head of the "research" division. He bragged that his store could track customers so accurately through their purchases that he could send targeted sales supplements to expecting parents, in some cases, <I>before</I> the wife informed her husband she was pregnant.

Back before music fans morphed into gaming fans, before lip synching became the rage, before utter horseshit like American Idol was even a wet dream, there were thriving clubs and committed music freak club owners like Clifford Antone.
