You will only determine what sounds "better" by trying the Herron. Subjective and just and endless debate if an internal vs separate is "better"
There's a reason many like the Herron, but it's not 100% liked as anything.
It's already apples and oranges since it's SS and the Herron is tubed.
The positive reviews on both mean nothing in the end. Your Rega and Thorens will sound very nice with the Herron. You may hear it as more "realistic/organic." Or, you you find your present setup is fine.
