analog newbie question/vinyl weight


sorry to ask such a basic question but I'm new to vinyl so bear with me. What are the differences/benifits between different record weights, 120g or 180g for example.

Agreed, stltrains. The Triplanar does make life easier.

Well, Dre, since Chester, NH, is the audio capital of the world, it did make sense. You remember those McDonald's signs claiming so may millions sold? not even close. :-)
Funny Dan, but I thought the audio capital of the world was in a barn in rural Pennsylvania somewhere...
Luke,

Be aware that using the weight/thickness of an LP to estimate arm height is only valid when comparing LPs on the same record label (and from the same pressing plant and era). Different plants and engineers used different gear and adjusted it differently. Therefore, cutting stylus SRA's vary widely between similar weight LPs on different labels. A 180g Decca/London will not want the same arm height as a 180g RCA or Mercury or MFSL reissue. Not even close.

We use weight (as a proxy for thickness) just as you're planning to, but only within the context of a single record label. We have a baseline setting for a typical weight on each label, then adjust for different weights from there.

That's still just an estimate of course. Fine tuning for each LP is by ear.
Doug the Luke method is the only real way to get it right or i should say get it to sound right to your ears.

I sent in my TP last month for a check up and on return decided to spend the time to listen for those changes from different VTA/SRA settings since i was starting from scratch. In the end my previous settings were high with arm height, and i knew UNIverse likes in low in the back. I listen to blues and classic rock mostly and like a sound thats more on the bright side of things. To my amazement you dont loose that nice tingly sound when you lower the arm instead you get that and better mids, bass, stage and sound thats fantastic/more seamless. The funny part is i thought my setup sounded good before i sent my TP in go figure.

I love vinyl playback with its hands on routines what i needed to learn and after 40+ years of hands on, you should never think you know it all and sit pat.
