Cartridges in general


The MM thread is in decline because the driving force Raul left his own thread. Besides the thread become to large so not easy to find whatever. Meanwhile J.Carr made the suggestion to extend the thread such that it would include electret , electorstatic and optical kinds in addition to the usual MC and MM kinds. J.Carr is invited to give some
kind of introduction to those 'strange kinds' of carts as the start for this new thread.

My friend Dertonarm try to convince me to use a SUT 10 years ago. I was
scared by their complexity as well by my own perspective with my + 40 MC
carts because I thought that ech of them would need an special SUT.
The ''pudding methaphor'' crossed my mind recently so I started with the FRT-4
which can be used with the most MC carts . The price which was lower than any
of my MC carts was an added argument. I was so surprised with the result
of  proof ( aka ''the pudding'') that I asked myself what the result would be with
an more expensive SUT? This kind of questions ''explain'' my + 40 MC carts
btw. So I bought the Denon AU-S1. Build like a German tank but with the minimal wire connections possible. A kind of simplicity added to complexity.
There is no way back to exotic and expansive MC phono-pres. I should listen
to my friend Dertonarm 10 years ago.
Hi analogluvr, Yes much better but I need to confess that I am a novice in
this domain with limited experience . I own only two SUT's  which I mentioned
while I started with the FRT-4 only 4 months ago. There are many members with
more extended knowledge and experince than me. They should provide better
information about comparisson between those two. The more expensive FR SUT's are made for specific impedance while the FRT-4 is made for ''all purposes'' with 3 , 10, 30 and 100 Ohm as well 3 input possibilities and bypass.
This imply many wire (aka ''soldering points'') and cheap (aluminum) switches.
The transformers by the Denon are direct connected with the output and input
connectors reducing '''soldering points'' to a minimum.

Given Raul's fondness for MMs and MI cartridges, I've never understood his outspoken aversion to MC step-up transformers. True, a stepup transformer will increase the magnetic distortions of an MC cartridge, but the larger magnetic circuit of an MM or MI cartridge has the same effect. I don't see why one approach should be favored over the other.

The reason you might want to avoid an SUT is simply that they are an added source of distortion with loss of bandwidth; ultimately an impediment to transparency. Also the loading of the output is critical for best performance (otherwise the transformer will not have flat frequency response and may also ring at high frequencies) and this will vary from cartridge to cartridge. Thus it is likely that most SUT setups are not optimized!

The flip side of the coin of course is if there is no SUT you have to have enough gain to deal with low output cartridges! In my system, even though we had the SUTs properly loaded, they were never as transparent as simply going direct. I found that if the SUT was in place I was simply less likely to play the system.

I am not saying SUTs can't be excellent- they can. I am saying that its possible to do better.
Nandric,  Is that you in the photo?  What is it you are drinking, or are you offering all of us a drink?  A fine cognac, I hope. In the tiny photo, you look a little like one of my favorite American actors, Martin Landau.

I've had thoughts of finding and buying the correct Ortofon SUT for the MC2000 that I bought from you and which I continue to enjoy.  Just out of curiosity.

Carr's post reminded me; is there not a new cartridge just recently introduced that places the coil (MC type) right above the stylus tip?  Can someone jog my memory?  Also, I hope Jonathan will stay on board with this thread, as he obviously knows more about this subject than any of us can imagine.  I would like to read a word or two on strain gauge designs, esp the vintage ones, if Jonathan is reluctant to discuss the Sound Smith product.
