Leonidas is amazing.
Is it just me, or is there a distinct Effect Audio house sound? Between Ares II, Thor II, and now Leo, I hear a marked liquidity and awesome smoothness I don't find in any other manufacturer.
Where these three cables depart is in tonality and transparency. Leonidas is the most transparent, and has warmer bass and mids than Thor II, but less inhibited treble. In other words, tia Fourté's highs are just as bright as ever, but it doesn't feel as bright due to the warmth of the other frequencies. Whereas Thor II smooths out and tames the treble to achieve a type of warmth, and loses some transparency in the process.
I asked Eric if EA had a cable that could compete with the plusSound GPC I found so wonderful for Fourté, and right now I'd say Leo more than competes. I can't wait to listen further.
