which is better ? MC phono stage or MM+step-up ?

Amazing! I called Michael Percy and ordered the Cardas plug and the XLO(30guage) wire,before reading the last 2 posts! Great minds think a like! I plan on building the phono cable to be as short as possible.Maybe velcroing/screwing the SUT to the back of the TT.I was also thinking of wiring it directly to the SUT without using RCA connectors.Please tell me what you think of these ideas.They are not set in stone.

I have fixed the sibilants problem. I have a very cheap NAD PP2 phono section.The "stock" load for the MC side was 100ohms. I found the resistors and changed them out several times before arriving at 470ohms.This was BEFORE I built the SUT.I didn't think that the different load would effect the mm side of the phono section.I then tried changing it back to 100 ohm and boy does it sound much better now. No more snakes!The sound is starting to be scarey good.Too good for the money not spent.
I can only think that the additional loading either added or multiplied the mm impedance on the mm side.

I can't thank you guys enough for the lively discussion of ideas and also the suggestions.This is the kind of stuff that makes this hobby great.

In 2003 I started to use a Kondo KSL transformer with my LOMCs. In Germany not many people were using SUTs at that time, it wasn`t really popular. In the beginning I was not really happy with the MC output of the Lamm Lp2 DeLuxe, so I tried the MM with the KSL - and vroom, usally at 3 Ohm, only the Kondo IO-j at 1 Ohm.

Now I have 4 KSLs serving 2 Kondo M7 phonos and another SUT serving the Lamm which is rebuild now and has better and bigger Jensens. Only Boulder and Zanden phonos I use without SUTs. I will never abandon my transformers.

Oddly enough when I changed to the 100ohm resistors the hum problem when I had another cable plugged into the pre disappeared. Just dumb luck but I will take it.I still plan on building a short cable from the tonearm to the SUT.Just waiting on the stuff from Michael Percy to arrive.
these trannys rock!

I have constructed the new tonearm cable using a Cardas DIN plug and .28guage XLO triple shielded wire.It is less than .5 meter long.The wire fit perfectly in the DIN plug.

The sound: Sound floor is lower.High transients are more apparent.Bass seems softer and smoother,it is still there but with less authority.Hum is no longer a issue at all.Sound stage is significantly wider and deeper.Voices have significantly more texture. Strings sound more wooden and organic.

I think that this is a winner.Considering that it is brand new without any burn in,I have to think it will get better and better.

I also think that it will take a VERY long time for the cable to burn in. Does anyone have a idea how long I should expect this to be?

DIY analog: nothing but fun.

DIY SAMA project is next.

If you have a low output cartridge, the phono cable will need a good 200 hours. Its best if you don't disturb it!
