Best SUT For Van Den Hul Crimson Stradivarius cartridge
@elliottbnewcombjr what is the difference between Impedance selector and load selector? https://www.ebay.com/itm/KONDO-AUDIO-NOTE-AN-S7P-MC-STEP-UP-TRANSFORMER-JAPAN/123923446228?hash=item... Thanks |
@lewm Yes, I realized that one cannot increase the impedance by connecting resistors in parallel. I have a Ypsilon MC26L SUT for Ikeda Kai cartridge which has 1:26 turns ratio. 57K||26x26= 84ohms. I belive the internal impedance of VDH could be 20-40 ohms and 10 times would be 200-400 ohms. In my case, the ratio is much less and what I am hearing is very high, high frequency response and decreased bass. I am not considering changing the line stage because I read good things about the SLP05 and does a good job with other cartridges. |
@lewm thanks for all the explanation. I have read about 10-20 articles detailing all about impedance (47K)/square of turns ratio and how to modify the load using parallel resistors at the out put and in put. If I use 1:10 turns ratio, the cart sees 470 ohms. I also know that, I can calculate the parallel resistors I need to use to decrease the loading. What I am struggling to understand is the following, what is the best loading for a given cartridge. For example: the VDH Crimson Stradivarius says optimal load impedance of 20 - 600 ohms, which is such a large range. I contacted VDH to tell me the exact internal impedance of the cartridge. If they say the internal impedance of the VDH is 20 ohms. Then how do I use that number to come up with the best loading. |
I heard magic today!! I set up Ikeda Kai with MC26L, VPS100 and used smartractor and Analogmagik to setup the cartridge. It was pure magic. The best setup I heard so far!! (my sound memory is not that great!!) I would like to thank @fsonicsmith for letting me listen to his system which encouraged me to go for that magic. I had listened to a 1000K Greg Beron system 1 yr ago. Analogmagik really helped me to setup accurately. I used my DIY Cables using helix geometry (I compared mine to high priced cables three different brands in total in 5-20K range), I don't want to reveal names and step on anyone's toes. I made DIY sound absorbers and diffusers. I leaned so many things in the last 3 yrs from all your help in the forums, articles, etc. My VanDen Hul crimson is in for tuneup and I will report once it returns in a few weeks. |
@lewm i always knew that VDH is a poor combination with MC26L. Which is why I asked which was the best SUT. then I went on and learned about impedance matching, what exactly it means, etc i had email exchanges with Dave who even sent me different data how SUTs work.. I even experimented with changing the input loading and output loading.. I am learning and having fun!! |
@fsonicsmith even though your post sounded dismissive, your intentions behind the post was for me the get the best sound out of my system.. when I met you, my skill and audio knowledge was let’s say 1, now I have come a long way. of-course I spoke to many you referred me and learned form many on the way.. I learned about room acoustics, made my own diffusers and absorbers.. I will compare mine to still points in the future.. I learned a heck of a lot about cable design, material, dielectrics and terminations.. experimented and made my own DIY ICs, speaker cables and power cables.. I also ran 3 dedicated 20amp lines.. that’s my personality, learn and improve!! |
