I would definitely take it slow before dropping down 5K on outdated technology. The Minimax is that good and it does get better with tube rolling. Telefunken smoothplates didn't work well in my system, better focus, detail, imaging but the soundstage lacked in comparison to 5814A. I have some Mullards boxplates coming soon which are very musical tubes and should match well in my system. I have updated the fuse to a silverstar hi-fi fuse and JPS digital AC powercord. The level of detail, richness and imaging is fantastic with a deep soundstage. The CD2 is great player but it's even better with the EE. EE sound is much smoother and less fatiguing.
