Stepup or phono preamp help

I know i have asked this question before, but i want to upgrade the amplification of the phono signal going to my integrated amp and looking for some advice. I know there are a lot of opinions on what is best but i am a little confused on which way to go. My analog system is a maplenoll ariadne table/arm combination that has been highly modified with a zyx universe SB cartridge .24mv output. The Integrated amp is the Marantz sr9300 and the speakers (for 2 channel mode) are vintage Klipschorns. I have been using a rotel 970sx phono equalizer that I have used for many years but the gain is marginal for the zyx universe and it has only a 100ohm input setting. I also have an older Vandersteen OL1 with adjustable input settings but the gain is not sufficient for the system (have to crank up the volume to get the sound to reasonable levels). I did use both in series to get to the desired 125 input but again the gain appears to be too low. Hence my reason for upgrading.

I am interested in opinions of equipment to boost the signal without increasing the baseline noise floor. Right now it is pretty good but i suspect I can improve this a lot. ALso, do i use a transformer and phono preamp, Transformer alone or phono preamp alone. I am not sure if the vandersteen OL1 is considered a sut or preamp but running the vandersteen in series with the Rotel did decrease the noise floor slightly and seem to improve the sound.

My budget is open to about 2000 USD
