Does a turntable make a DRAMATIC difference?

I have a completely restored Thorens TD-125 with a Saec WE-308L tonearm and Technics EPC-U205 mkIII cartridge w/a new Jico SAS boron Stylus.  A huge plus to the phono system is being able to adjust the VTA on the fly.  I purchased a Fonolab tonearm adjustment mechanism.  Very simple cool item that took the tonearm to a new level.  Records are so varied in thickness now.  From very thin to 200 gram vinyl and adjusting from the different thicknesses makes all the difference in the world.  A record can sound dull and with a simple adjustment on the fly it becomes detailed and dynamic.  Or it can sound too bright and harsh and adjusting the toney down a hint makes it sound full and smooth and brings the bass in.  

A good preamp is also soooo important!  I had a very modified Cary Audio AE-3 phono pre in a larger chassis with a separate PS. It had the best Mundorf caps and extremely modified.  It was really good but then I picked up an old Theta Tube Preamp that I’ve converted to just a phono preamp.  I completely updated and rebuilt the PS board in it and installed a few hundred microfarad’s of Polypropylene Solan caps and a separate PS with a new toroidal power transformer and choke input and large value electrolytic and propylene caps. It takes about 3 days to fully charge and sound its best so it’s on all the time.  The phono and gain section have V-Cap TFT (teflon) caps and StealthCap Caps.  It now sounds more detailed and smother with a wider sound stage then my digital system which is fairly elaborate setup also.  Both are enjoyable but I really love and prefer the analog system now. 
 

Big areas of importance (but not all of course) are the turntable, isolation, tonearm, VTA, cartridge and type of cantilever/stylus, phono preamp and of course an excellent line stage.  I have a custom built hand-wired balanced line stage based on the Cary Audio SLP-05 but with a huge separate PS and all Mundorf EVO silver/gold/oil caps in the signal path.  My balanced output DAC feeds into the line preamp and the Theta Tube Phono preamp feed into the line stage and is converted to a balanced signal to my amps. 

I must add, regarding yoyoyaya’s post, for many years it was no contest that my analog side outperformed my digital.  It wasn’t til quite recently that digital became so exceptional that it surpassed records. 
I guess I have a very high standard in the sound I want, and probably will have to pay for it.

Since I have both digital and analog set up. Both set up are equally good for my taste.If I have time to sit down and listen without interruption, I prefer vynil. It took many yrs before I jump into vynil.I heard a good analog set up at audiophile house during a visit to a friend house. I was shocked.  I went home I was struggling to listen to my digital set up. It’s like the emotional feeling of the music all over my being is missing on my system. That’s when I knew analog is amazing if it’s set up and match correctly.Changing phono Cables helps as well.with Sutherland 20/20 . The LPS brings improvement on 2020 as well.

RV be patience on your analog set up at the end with all your hard work it will pay off.

Are you sure that your turntable is the reason why your analog sounds inferior to the digital?  I'm pretty sure that a better turntable would improve the listening experience, but will it get you where you want to go?  It is very difficult to test this "better turntable" theory.  Once you are sure that your turntable/arm/cartridge are setup correctly, what comes next?  I would think that you would then need to purchase a new turntable/arm and mount the Hana.  Prior to this, you might want to investigate what I found to be the issue in my system consisting of 20/20LPT and Hana.  See if you can find a local dealer willing to let you A/B your Sutherland in their store.  Let them know what listening experience you are after.  Make sure that the phono stage is capable of a fluid musical presentation.  Likely they will go for broke with the A/B, but at least you will hear the Sutherland under ideal conditions.  If the Sutherland holds up, then you will need to establish a turntable budget and decide where to go from there.  My Technics SL-1200G with my present setup now bests my Holo DAC DTE, where the Holo use to be much superior to my analog setup. Currently,  I'm sure that my Technics is the weak link, but at this point my bank account is even a weaker link.  BTW...everyone told me that my problem could not possibly be the 20/20 and I just needed to let it break in..and I did...that I needed better power.. so I spent a fortune on conditioner and power cables.  Then, against advice, I got rid of my 11/2 month old Sutherland and went for a more musical phono stage.  I'm being vague here because I'm sure that you can make such an upgrade in a much more cost effective way then what I did. I've only had the new to me phono stage for a few days, but it only took a few seconds to hear a a major improvement in musicality.  That first day I went from Ella and through two Billies and a dozen other male and female vocalist as well as rock and classical.  Everything about the presentation improved in a big way.
