Upgrade from TW Acustic Raven AC-3 to what?

Well, unfortunately it is not the way to success (whatever this will be) to think, that a design has to be better when it is more expensive. Probably you should look for a better design instead of a more expensive one.

Most Audiophiles have experiences, some have dreams (in a positive way), some have an altar and all listen to music. Some to originals, some to reissues and some use it to relax because life is boring otherwise :-).
No matter what the direction is, sooner or later some (not all) will realize that a cow can't be a race horse. No matter what you do. Some try to do that with better food, with training... but at the end of day (and the next...) it is still a cow.

Just an example what is going on when you listen to analog:

The dimensions from the contact diamond in the groove are microscopic and to show in what huge lever the cartridge System "sits" (to be able to realize that even the "tiniest" distortions will have their result in the sonic presentation),
imagine the following:
Multiply all datas from your Tonearm with factor 100.
With a regular Arm this one will have a length in the area of 27.3 yards, the cartridge System is about 1.09 yards in height, the cantilever about 0.5 yards and the contact are from the needle is in the area of 0.0196 inch.
The Mass has a direct relation to that sizes - well and this will be "disturbed" now by additional vibrations from outside ( can be from motor, belt, platter, bearing and so on)
The influence from tonearm (bearing etc.) or cartridge is not included

Turntables have something to do with science, even when some deny it and prefer a proper painting instead. I forgot, how about a rumbling wheel with direct contact to the platter...the low frequency is not the subway below Kingsway Hall or PRAT in reality :-)
Here you have the reason why tables "sound" different, or why a cow can't be changed to a race horse, even when you hug it :-), but probably it will learn to fly. Who knows....
This is only the vibration, we didn't discuss the quality from material mix, the influence from the platter, the quality of motor, belt or string ...

...sorry, Syntax...

I know, I was born to suffer... (sic!)

Audiophiles "opinions":
"I wrote it the right way, so it was copied the wrong
way right. I mean the right way wrong." :-)

This discussion is going in a direction that isolation (passive or active) is the solution for everything. I am sorry to say, it is not. It is a step up in Performance but an average Turntable placed on a isolation device is still an average turntable. It only sounds a little bit better than the same without it. A cow will be no horse.

I give up

A cow will never be worth the price of a horse. But maybe in a world of blind it will be different.
The typical audiophile will sit in front of his machine and will think
- Yes, that is it. A review winner. Component of the year. I don't hear it, but I spent so much money, it has to be better. the other ones say the same...
The Listener sits in front and thinks
- Man, so much money for such a cheap made unit
The Collector sits in front and thinks
- Yes, it looks good and no matter what is out there, I am the first
The experienced Audiophile sits in front and thinks
- Great. Let's go for Lunch
Times are tough, but modern
