Hey watch it, I resemble that remark!

[allenzachary]

It's a line from one of the videos about LP manufacturing.  The announcer makes us sound like kooks.

[richidoo]

It's ironic that the "How it's made" narratives are written by the featured manufacturer. I am not realy surprised if that's what record plants think of us, after all they are audio pros. I can hear it now, something like "Only deluded audiophiles and teenage rock kooks buy vinyl these days, but we're happy to take their money..."

I still resemble that remark (and am damn proud of it.  )

And oh by the way, I have been involved in this hobby since before the CD was introduced and in all those years I have never brought somebody down to the mancave played them a CD and LP of the same recording and not have them say something like "Holy Cow the LP really is better sounding."  Now a few of them have said that not withstanding the better sound they would prefer owning the CD because of the hassles of owning and using LPs (cleaning, TT set-up etc), the lack of surface noise on the CDs, the cost of a good TT setup or simply the fact that the sound of the CD was "good enough for them". 

Now these are all valid reasons and the decision point of whether better sound of an LP system is worth money time and sometimes aggravation of owning one is certainly a personal choice (I vote yes but YMMV), the fact remains that while  not everybody left the mancave saying that they were going to run out and buy a TT they all recognized and acknowledged its sonic virtues (and some of its warts as well.)

So it may be largely "enthusiasts" that  are willing to lay out $ for LPs and LP playback systems, but in my experience when exposed to a properly set up system, even the average Joe appreciates them.

I used to own a nice turntable (Thorens) with an English tonearm and decent cartridge, until I dropped it while moving pieces around.   

But by then CD players were becoming "affordable" and I'd been developing a good system (large/expensive 3-way speakers with transmission line bass, the original Hafler pre/power amps) that was supposed to be "digital ready".  So I made the leap and never looked back.

Since then I've heard several high-end vinyl setups, but now I'm spoiled, and have zero tolerance for surface noise.  I'm a "speaker guy" but surface noise is my weak point and I'll never go back.

Thank goodness there are different folks with different strokes.

And if surface noise is your hot button then going CD is far and away the best move for you. As we have said many times in audio, the only "right" decision is the one that makes you happy, in spite of what anyone else might think.

I wish the people making vinyl today had a clue about how to actually do it.  The latest pressings I've heard sound like they held up a boombox to a mic to make the master.  The art is dead from what I've heard.
