Holo Audio May DAC Version

Hello everyone, I am about to make a purchase and would like to know if anyone has any first hand experience between the version 2 and the KTE. Is it worth the extra money? I live in Greece and the difference is quite a large one. 4750 euros for lvl 2 vs 5600 for KTE. I had an audition at a local dealer of the spring kte vs my dac, chord hugo tt2.

The improvement was heard within the first few notes. And the dealer told me the may is at least 40% better sounding than the spring. The main differences I heard was in the bass department and in transparency. The tt2 has a warmth to the bass which is not needed in my system. It has an extension which can sound boomy at times. Also, the instruments sounded more at the level of the speaker, whereas with the holo, it pushed the stage further back and had a more 'realistic' tone than the 'richer/warmer' tt2. Anyone heard the differences with the may v2 vs kte? Any advice is more than welcome! Cheers
