Make a trasnformer hum 101
^^ How about a power conditioner for SMPS and a separate power conditioner for everything else?  :) 
Make a trasnformer hum 101
One issue then would be - what to do with SMPS, wallwarts or otherwise, that are now prevalent as part of an audio setup. 
Confessions from a VPI owner of some 30 years
Not sure I understand.  You had an issue with your SDS.  It took a while but VPI stepped up to the plate and replaced it with a brand new ADS as the SDS was being discontinued.  The ADS is apparently working fine.  Maybe it is just me but I dont k... 
Insane ground loop; anybody wanna try?
There can be a combination or cumulative effect of issues. 
Insane ground loop; anybody wanna try?
Are you sure it is a ground loop and not EMI/RFI?

SUTs and Resistive Loading Questions
I agree less is more (and thus don’t like using more connections, resistors, etc, than necessary), but this is about trying different loading with a cart/SUT/phono setup to see what sounds best. If the resistors make a difference, then I would mos... 
SUTs and Resistive Loading Questions
Larry, thats what I intend to try. It is easy enough. Lew thanks for describing the other options on the primary side. I will look into it further.As for the need for a SUT, my pre has sufficuent gain for a MC but my experience is that using a SUT... 
SUTs and Resistive Loading Questions
You are correct.  I fixed my prior post before your last response. 
SUTs and Resistive Loading Questions
Al, you are correct. I need to take into account the SUT with a 100 ohms setting on my phono preamp. But if you run the calculations as if loading on the secondary side, doesnt look like I will be able to do it - Id have to increase load, and that... 
SUTs and Resistive Loading Questions
I'm familiar with the Rothwell site and links.  Thanks.In a prior setup, I did notice a difference between 100 versus 200 or 470 ohms.Cart is Dyna 20x2L. 
recommendations of phono preamps < $3000 range
Lehmann audio decade. 
VPI paper alignment jig
I also recommend a Mint Protractor.  It's mirror surface and alignment lines/curves to prevent paralax is worth it. 
SUT shootout
If you collect carts, you probably will need to collect SUTs also irrespective of impedance ranges. ;)Im looking at a Hashimoto that suppposedly has a switch for 2-7 ohms and 7-40 ohms. Other SUTs like Bobs Devices have similar switches. 
SUT shootout
SUTs are very cart and system specific.
