First , all Step-Up Transformers are made to go into a 47,000 ohm Phono Input. Your combo of Transformer and Cartridge were made for each other , so go with the 47k . Capacitance isn't as critical with MC Cartridges . Experiment and go with what sounds best .
That being said , I am wondering why you aren't using the Denon SUT into the Phono Input on your VTL Pre . I have had great results with Transformers in front of my VTL Ultimate as long as you set the Input Impedence for 47,000 ohms . You keep the Tube sound that VTL is known for without introducing Transitors to the Audio path .
