Dear @montaldo : """
I think our respective objectives in this Pursuit might be very different. """ Could be you are rigth.
My overall room/system target ( main target. ) is that what I listening through it be stay nearer to the recording.
Then my quest is to acieve that target that puts me nearer to what the recording microphones pick-up that puts me nearer to the " real music " ( it's imposible to mimic live music experience in any room/system. ).
For that can happen the room/system must be a very high resolution one and at the same time with very low distortion levels at each singhle link in the room/system audio chain. That is true HiFi, not what refferd Tom.
Now, in " paper " those Jensen are very good transformers and for many years Jensen was and is a reference in audio, several high end manufacturers use it:
https://www.av-iq.com/avcat/ctl1642/index.cfm?manufacturer=jensen-transformers&product=jt-347-axt
I know that numbers does not say all but are important.
Hashimoto as other transformers are good too but in the case of the Hashimoto and due the way of thinking of the manufacturer amybe just maybe what you are listening trhough it more than a real an better " dynamic " characteristics against the Jensen in your Berning been only a different kind of distortions not only because the SUT but because the additional IC cables and connectors.
I think that way because you said the differences for the better is not a tiny one but something important.
In the other side, through the years you owned the Berning and after the burn-in time the quality level performance of that unit changed in any way?
Because could be too that through the time something " degraded " the Jensen performance as " cold " wire solder down there ( with so many wires. ) or even one de-soldered.
It's imposible to figure out what is happening in your room/system because no one here already had your experiences betwwen the Berning and the external SUT.
Btw, @mulveling the KRSP ( that I owned. ) is way different to the Koetsu OP model. The KRSP output level is 0.2mv and the OP is 0.4mv. As a fact both models only shares the Koetsu name because the quality level performance is way different in favor of the KRSP.
