@jmphotography Welcome to the world of thoroughly enjoying LP Replays.
Prior to spending more substantial outlays of money, I think there are few avenues of investigation that can be looked into, that might prove to be beneficial to your situation.
Initially looking at methods to support the TT and Isolate it from the Set Up environment can provide quite noticeable improvements to the SQ, if done correctly Detail Retrieval and the Bass Line should become cleaned up.
A Couple of tiers of Sub Plinths can be used on the mounting shelf, with a few different footer types in between or if the interest arises to experience a Wall Shelf, this design can be used and then have a Sub Plinth/Plinths placed on it to see if further improvements is available.
Sub Plinths and Footers need not cost the earth, and can be created very economically, a friend swears by a sand box as his ideal Sub Plinth with a DIY Copy of a Footer I use.
If the Sub Plinth Method is investigated and a method is discovered that is proven to be an improvement and satisfying, a further investigation into Platter Mat Materials and Spindle Puck Weights can really show an improvement, this type of investigation can take up some funds if Loan Mats are not available, but there is a discovery to be made that is worthwhile of the endeavour, a good starting point may be to see if there is a trend on your TT model for a certain type of Mat Material.
I have maintained my interest in the above for too many years and have collected a quantity of Sub Plinth Materials and Platter Mats, which I am still keen to bring something new to the set up.
Every now an again these are loaned out to a local HiFi Group and the use in other systems are assessed, the responses of system owners usually to great surprise and most systems I listen to have a Mat in use of a Material that I have introduced and most TT's are sitting on a Sub Plinth and a version of footer I have introduced.
Recently I took my most recent acquired material which is Panzerholz to a friends, and after a period of time placed it upon the CDP Mouting Shelve and under their Valve CDP.
The change in the performance was noticeable immediately and that was without footers being used. I then added AT 616 Footer under the CDP and the whole presentation took on a added attraction.
The P'holz and AT 616 Footer is to undertaken again with an increased number of attendees and a few different footer options.
Getting this side of the TT correct will allow for the TT to offer its best and any other trials with devices will be best served with this as a starting point.
