Entre' ET-100 SUT

Posted this on Vinyl Asylum.  Thought I'd try here too.

Hi all,

I've been looking in to SUTs and my word it is remarkable how varied opinions are on just how best to think about loading and voltage matching.

In light of that, and in light of the fact that I have a three armed system and a variety of LOMC cartridges (nothing fancy) with a variety of output voltages and impedances (5-40 ohms, including Denon DL-103r (14ohm, 2.5mv) and DL-301II (33 ohm, .4mv)), it seems a good way to go is with an SUT that has multiple inputs and variable settings.

One such is the Denon AU-320 (or 340) but that gives only 3 and 40 ohm options (and pass through). I had a Denon AU-300 before, and quite liked it.

But another option is the Entre' ET-100, which has three(!) inputs and three settings. There seem to be two versions (3, 10, and 40 ohm; 3, 20, and 40 ohm) There's a slew of them available used from mostly Japanese sellers.

But the thing is, I can find almost nothing about them online -- no reviews, no complete specs (step up rations for the various settings), no discussions. Without knowing the actual step up ratios, I wouldn't know whether to get the one with the 10 ohm setting or the one with the 20 ohm setting, if I were to order one.

So, anyone familiar with these things? What can you tell me or where can you send me?
