Analogue front end. You want more weight, scale and dynamics.Where do you start upgrading?

Recently added a SUT (Zesto) to my Rega Naia/Aphelion2 rig, and that brought immediate changes in oomph to the sound.

In terms of physics, it should not make an iota of difference, but it does. Take that from someone who has never heard a difference in any cable. 

Weight, scale and dynamics will improve with better turntable isolation if you don’t already have that sorted out. That happened for me when I went from an isoAcoustics Delos to a HRS R3x isolation base. That was an eye-opening game changer and really sold me on the importance of mechanical isolation for a turntable.

 No doubt. HRS are expensive products, but if you have high end turntable..

Mass loaded turntables are known for their ample bass weight.  Better scale and dynamics are more a function of preamp/amp and/or speakers.  A cartridge can sound faster like the lightweight assembly in the MY SONIC LAB - Ultra Eminent Ex MC Cartridge, but that isn’t what the OP is asking.

Although the OP claims that 60watts is plenty, it really depends if the speaker is efficient enough including impedance considerations.  Typical wattage is ~150-300wpc for average sensitivity speakers.

It all starts at the source, which is what you put it on, as pointed out above HRS stands DO make a difference, anything to minimize vibration is a good thing.

I have 2 HRS stands and plan on getting another one, after that the turntable>tonearm>cart is the rank, get the best sounding table you can. even with a budget cart will do better than a lesser table with a better cart. I prove that to myself at home with multiple table/arm/cart set ups.
