Curious about the difference in what I’d hear on different tonearms


I’m relatively new & most of the numbers & concepts people talk about are still over my head. I do basically understand that different tonearms are a better match for  certain weight cartridges. To reduce the variables I have a Lyra Delos cartridge & a Rega 330 Moth tonearm & I only want to compare up the Rega models without advice thrown in about different cartridges.  Here’s my question, with that setup & all other things being unchanged, what actual difference would I clearly hear if I changed the tonearm to the Rega 808 & then between 808 & the 2000? Please-“I’d never use a Rega... get an ABC model 1234”, same related to the cartridge or other parts of my system... it’ll just confuse my understanding of what you’re teaching me.

Thanks

Your specific question was really very narrow. You really needed responses only from persons who have owned and used the rega 303, 808, and 2000 tonearms, if I understand your post correctly. Which is why I did not respond, except to Mijo on his political comment. I actually wonder whether anyone here has had personal experience with even 2 out of 3 of those particular Rega tonearms.  I do have one opinion that you might find useful. I partially disagree with Miller carbon. The interaction between the headshell  and the cartridge is also very important in determining the ultimate sound quality. Certain headshell materials seem to work better with certain cartridges or cartridge types. If you were to find that one or another of those rega tone arms sounded best, it might well be because of a favorable headshell match, assuming those 3 Rega’s might differ at the headshell.

I have had a couple of 3 Rega tonearms and there is not much difference. In the confines of your your question you may likely conclude that there is little if any difference in tonearms. That would be an incorrect conclusion, but seemingly correct due to your sample. The Rega tonearm is good for the money.

If you are actually interested in the difference between tonearms you will need to expand your sample.

Best of luck.
