11k seems a bit high for a cartridge in the 450mH area. I don't have numbers for the new stuff but my ATs are 360mH or less. I would expect you to need around 7K to get the 2122Hz pole. Hans simmed it with Marcel a couple of years back and here are is the quote from his post
Now this was pushing the limits of noise for MM stages mind.

I will be happy to repeat with Hans' values. I think, however, we are straying from the OP's purpose which is PS related.
Looking at the Measuring phono stage RIAA accuracy with a computer
I did not stimulate the cartridge -- a shortcoming in the measurements and looking at the thread a daunting task! (It took me a day to remember where I had seen the chart).
In any event, the LR Phono Pre seems worthy of a thread.

I ordered a SilentSwitcher, and I have the AMB sigma22 with transformer.
I'll try them both to see if there is an audible difference.
I would also be interested to measure for the learning experience, but I may not have the appropriate tools.
I have a Tektronix 2235A, a Fluke 87V DMM, and PC w/ ARTA and Pete's sound card interface (I also have Jan's autoranger on the way).
If possible, could someone recommend a useful test here?
