Help me understand cartridge alignment
Raul, in that interaction you were per usual arguing the superiority of Baerwald vs Stevenson. We were not discussing the importance of very accurate alignment. Perhaps it is you who have the faulty memory. Also back then I was reporting a problem... 
SUT - electrical theory and practical experience
Dave, I’m getting my Festivus pole out of storage now. I just aired my grievances with my wife. Then we’re going out for Chinese food.  
Help me understand cartridge alignment
You are wrong about my "opinion". For most of my audiophile life, I went along with the idea that very precise alignment is important. Only in the last few years have I begun to seriously question that proposition. And the key word is "question". ... 
Help me understand cartridge alignment
Raul, I just saw your post. What is "tracking distortion"? Are you talking about harmonic distortion, IM distortion, or what? Can you refer me to the source of your data, or have you yourself made these measurements? I am certainly willing to beli... 
SUT - electrical theory and practical experience
Holmz, Make no mistake, Dave (Intact Audio) knows more about this subject by far than I ever will. So if my advice to check out the Jensen website seems counter to or only partially correct in view of Dave's insight, go with what Dave says.   
SUT - electrical theory and practical experience
Holmz, you ought to visit the Jensen Transformer website. There you will find erudite discussion with schematics and other data regarding how to load a SUT. Plus the engineers there are nice guys who might help with your specific questions, if you... 
Aftermarket power cable on Sutherland 20/20 MkII
Do Sutherland offer the unit with two separate LPSs as a further upgrade?  
Aftermarket power cable on Sutherland 20/20 MkII
Thanks, aud1. I have seen the photos on the Sutherland website or in the Music Direct catalog that show the unit with cover removed, revealing that there is an empty space in the chassis physically separating the two channels by several inches. I ... 
SUT - electrical theory and practical experience
Some of us find the science of these devices to be interesting per se.  Some others do not.  Based on his posts to start the thread and subsequently, I judge that the OP is one of those interested in the science. If he thinks the thread has drifte... 
SUT - electrical theory and practical experience
antinn, In your quoted paragraph, I think they are using "Watts" as an expression of acoustic power or energy.  On that assumption, and wanting to know how acoustic watts is defined, I found this on Wiki: "Sound power or acoustic power is the rate...

“Dual mono” is about the internal build, not power cords or the external AC.  
For owners of Allnic phono pre amps
I’m not an owner, but it seems to me that before you’d pay the high cost you would want to be sure the built in SUTs are of the highest quality, because that’s what you’re paying for. For that kind of money you can buy the best of the best outboar... 
SUT - electrical theory and practical experience
"That manufacturer said that a LOMC ( with out SUT ) has a rise time between 15 to 21 microseconds and MM between 23-31 msg." To the best of my knowledge you never previously mentioned the data for an LOMC without SUT. Anyway, I doubt any of us c... 
SUT - electrical theory and practical experience
Raul, I see now that it was you who posted the rise time data, which are based on your memory of something published by an electret cartridge maker who, from your memory, is said to have stated that his cartridge has a rise time of 2 microseconds,... 
SUT - electrical theory and practical experience
Holmz, where do the data that has caused so much angst come from? (Rise time for MM at 1kHz is 25 microseconds vs for MC+SUT is 30 microseconds.) what cartridges were used? What SUT? After how many hours of use? Etc, etc. Thanks if you can referen...
