Why you’re not crazy to use repeating coils/bridging transformers between digital and analog audio.

Finemet has a few different line transformer options, has any one tried?

Currently using their SUT which sounds amazing. Tempted to try one of their 600:600 line transformerS

Stumbled across these Finemet 600:600 transformers on the auction site for a great price. I guess I would describe them as mostly transparent in my system with a Denafrips Venus II DAC. There may be a marginal improvement in clarity. I'm leaving them in. I assume they were somebody's DIY effort.

I just uploaded my journey using line transformers for digital audio.😊

Have you ever tried the 111Cs wired up 150:600 per the WE111C data sheet?

So is there a Lundahl PN suggested for this DAC application? Seems like the would be readily accessible compared to auction search and of recognized quality build if so.

Honestly, I'm unsure where to land in the attached options below - there are several 600:600 listings in the Jensen line [I actually have a set of Jensen JT-123-FLPCH left from a F6 amp parts accumulation before tubes grabbed my interest] and there are 1:1 offerings in the Landahl line. Pointers appreciated!
