Amp came right when promised in the excellent condition that was expected. I love this little amp and would definitely do business with this seller again.

Got exactly what I wanted, shipped quickly, in excellent condition. A+

I'm all over this

Really want to hear the Soekris sound and this DAC in particular would fit right into my system. Also interested in a 1421 although I don't really need the head amp.

Quote: I'm really not following you here.  Of course you're measuring SPL, that's what the doohickey does.  I'm asking what you do with that information and why A is "invalid" for that purpose.  I'm not trying to get you in a gotcha here, I truly want to understand.   Quote:   I...

Again, you're confusing audibility and perceived loudness with other reasons for measuring sound.  Recall that phons are based on perceived loudness.  A-weighting is an effort produce a single-number representation of sound that roughly corresponds to human perception in that area.  C-weighting...

Quote: It's confused.  It can't decide if it's talking about RMS or peak (peak to peak?  or just peak?).  It can't decide if it's talking about broadband or 1-kHz.  It feels like a translation issue.

I still don't follow you.  How does weighting make your measurement not "real?"  What purpose would an unweighted measurement serve?  I assume we're still talking about broadband, SLM type measurements, here.  The only time I've ever encountered a use for an unweighted broadband measurement is...

What is a "real SPL measurement?"   Why wouldn't you want to use an RTA to check spectral balance?  What other options are there?

I can't believe how much you guys care about something so trivial.

Quote: It turns out they're not too bad if what you're measuring doesn't have heavy low frequency and you're using the A filter (which probably all of them do).  I saw a paper on this at a conference in February, I think they determined that they're accurate to within ~3 dBA.  Definitely...

Part of the Dangerous Decibels program is playing a tinnitus recreation.  I will do everything I can to prevent that from happening to me.

Quote:   You're confusing the concepts of hearing threshold and hearing damage.  When you say A-weighting is "correct" at 40 phons, what you mean is it's better suited for considering audibility at low levels.  That doesn't make it "invalid" at higher levels.   A-weighting serves...

Last Week I attended a workshop to become a certified Dangerous Decibels instructor.  It's a program designed to get the idea of hearing protection into the minds of kids before high school cynicism sets in.  It's a worthwhile goal, as we are in the beginning stages of a hearing loss epidemic...

I agree, download them both and see which you like more.  They're both free and small so you have nothing to lose.  Spend some time with Foobar configuring it and installing some plugins.  I like Foobar more because I find it easier to manage my music collection, which is organized by file...
