I have the Bordeaux and Fuuga and am currently using the EMIA 1:14 Silver SUT.
In my system, the silver SUT is well worth the price difference. Jeffrey and Dave were generous in letting my try a couple different ratios to find the best one (and of course the one suggested sounded the best ).
The Fuuga is a great all around cartridge...does everything well and it has no errors of commission. I would describe the sound as very slightly 'tubey', i.e. slightly forgiving.
The Bordeaux probably retrieves more information and leans more slightly into 'analytical'. I have not spent as much time with Bordeaux/EMIA combination (have been alternating between the Fuuga and Etsuro Gold). Your post has inspired me to spend more time with the combo this week and hopefully I will remember to return to this thread.
I have no experience with the Etsuro SUT.
