@Roby79 your impressions will be interesting, as I suspect you will be the only member of the forum who has the chance for a direct comparison between Spring KTE and May - and indeed May L2 vs KTE. So...
1. What system was used?
2. Spring vs May.......overall, by what % was the May better and in what areas?
3. May L2 vs KTE.....overall, by what % was the KTE better and in what areas?
4. Is the May worth the extra over the Spring?
5. Is the May KTE worth the extra over the L2?
6. Did you compare The May's Internal OS vs NOS?
7. Did you hear what the likes of HQPlayer can do?
8. If going for a Holo DAC, where would you put your money and why?
9. Were you on your own?
Sounds like someone's about to go shopping.
