FIDELITY RESEARCH STEP-UP TRANSFORMERS

Has weight of transformers something to do with their quality?
I see that some refer to +10 kg. for Technics but Kondo-san
(Audio note ,Japan) weight about 500 g. i  own Kiseki MCT-2
made by Kondo san for his friend Van den Dungen and identical
with his own weighting only 500 g. I also own Denon AU-S1
(weight 3 kg. ) costing $ 3000 new and about $1000 second hand.
The price of Audio Note transformers would be very curious if the
thesis about weight-versus -quality relationship would be correct.

@edgeware lol
thankfully not my only cartridge then

Dear @lohanimal  :  At the end seems to me that you don't need any SUT.

Look Through 3 TTs I have mounted 10 tonearms/cartridges and I always use it only one phonolinepreamp and at each time that I want to listening another diferent of the mounted LOMC cartridges I only disconnet the tonearm cable and connect the cable of the other cartridge. This task takes me 1 minute to do it.

Now, I use ( time to time ) SUT's because I owned from several years now but normally I listen the LOMC cartridges with out SUT and directly in my active high gain phonolinepreamp that comes with two totally separated duaL MONO FULLY BALANCED MM and MC stages.

Repeat, I don't need a SUT and seems to me that you neither.

@rauliruegas I am also exploring a Manley Skipjack or other switching device. 
I just want to know, in part, why so many swear by SUTs

@rauliruegas 
My other option is a further phono stage with multiple inputs - my big problem is that I do not want a sideways or backwards manoeuvre given that both the phono stages I have are very good already...
