What Step-up transformers are best value?

Once again, many thanks for your replies.

I am interested in experimenting with loading. What value resistors should I try? I have no experience of this, and could do with some guidance. Where exactly do i put them?

I just received my June Stereophile today and see that Art Dudley comments on the Bob's Devices SUT and says that it is very close to one costing 10X as much. He says"For the LP enthusiast who has yet to experience the superiority of a MC pickup combined with a transformer step-up device, I can think of no better place to begin."

I've been using a VDH MC 10 for many years, I know its not in the same league as the BB but as its from the same family i will toss my $.02 to the wind. I've tried a few great Head amps (Pioneer HZ 1 was the best still regret selling it) as well as recently the Silk SUTs and older Otofon SUT and highly regarded Denon SUT and to be honest the VDH carts just sounds better with a Head Amp. even my VDH manual says they don't recommend a SUT. with the cost of the BB I would invest in a quality head amp/MC phono stage I think you will be happier in the long run.

For less than $700 get a Tavish design phono amp. MM/MC - killer. Want to spend around $1500 - get tehir TOTL phono amp with separate power supply - likely will never need anything else.
I also own an Auditorium Hommage T2 (which many claim to be one o fteh best if not the best SUT inclduing Sterophile) which costs much more, but the Tavish (very favobaly reviewd by several sites and magazines) holds its own. No affiliation just a happy customer.

Same with ZYX cartridges, people should try ZYX CPP-1 PRE-PREAMP (HEADAMP) designed by Nakatsuka-San for low output MCs.
