Its no secret that I am a total fanboy of the Sony WM1ZM2. I tend to find it analog in the way it reminds me of audio cassettes I grew up listening to. I find its bass very realistic and I appreciate the fact that it can thicken up the sound without veiling the treble.
However, bi-amping the WM1ZM2 with the Brise Tsuranagi makes a small but unforgettable difference. The layperson’s way of putting it would be that once you remove the Tsuranagi, the WM1ZM2 begins to sound a tad lackluster.

To put it in audiophile terms and audiophile terms never completely do such small but decisive differences justice, the overall presentation sounds faster in transients, more bombastic in bass, blacker in background, more micro-dynamics (e.g. inflections in singer’s voice), wider and certainly more deeper in stage reproduction. Also noticeable with the Sony IER-Z1R, that on certain tracks with the WM1ZM2, while mid-treble can be a bit zingy, adding the Tsuranagi in the chain removes the zing, sweetens up the treble whilst also rendering it airier?
I am quite certain I am not imagining all these differences on account of the $2700 I paid for this tiny amp, lol.
The biggest test for me was that removing the Tsuranagi from the chain made me want to end the listening session and start the day, which I need to do anyway.
