Because of the impact of CD's,and the negative advertising of competition,most vinyl lovers really have no idea how a well designed vacuum system can impact music reproduction.There are some vacuum systems that allow for the user to set vacuum pressure,which can be risky if you are inexperienced,and can risk too much pressure,which causes noise.Also it has been claimed(with no proof) that one can leach important chemical aspects from the vinyl.
In the SOTA(especially the greatly improved newer versions)this is all set by a computer chip,and the least amount of pressure is automatically selected.
I have had(as well as two friends)a SOTA vacuum system(in various models) for over two decades,without a single tick or pop,that I could blame on the vacuum system.
If digital had not become so popular,and tables still "ruled the earth",we would have heard LOADS more about the benefits of a correct vacuum system.Sorry,no amount of negative marketing could sway this inarguable fact!
I have no doubt the 20/2 is a fine table,but the Latest Cosmos IS a tour de force,both in design and sound.My last(older Cosmos)didn't even require a new belt,until I had it rebuilt(along with my pal's table),after twelve years.It operated flawlessly,yet the newest COSMOS "smoked it",in every conceivable way,when it came to performance.I had no intention of moving to the newer model,but when I heard my friend's update,last year,I was in "I'd even rob a bank,to get it" mode.This latest model designation is a powerful force,to be taken very seriously,especially at the "still" rediculously low asking price.
The 30/2,though,could be a different story!!Anything below that point is most likely going to be outperformed by the latest modded Cosmos.The problem,knowing "audio mentality",is that it's still too inexpensive.At it's current price.Hmm!!
Best!
