EF95 tube review

After testing all EF95 tube, IMO, Mullard CV850 and Electron Tube 5654 is the best EF95 tube. Maybe the winner from EF95 can beat easyly with EF92 or EF91, but just enjoy my short review

Detail character from each Ef95 tube :

1. RCA 5654 NOS is American tube, same as standard tube in Little Dot MKIII, the differences is NOS. But the sound not much different with standard tube Little dot MKIII.

2. RSD EF95 Germany, this tube chacarter is , more soul than standard tube. But the sound heard rigid, harsh in vocal when singer scream.

3. Sylvania 5654, this tube is broken, noise in everywhere. I put in the garbage

4. Ultron 6AK5, sound from this tube heard foggy, not transparant

5. GE 5654 and Siemens 5654, this is dificult to choice one from this tube. 2 tube sounds good, very relax, but i dont choose it because there is another tube with better sound.

6. Electron Tube 5654, this tube beat GE and Siemens because this tube have more soul, more balanced, good to acustic gitar and percusion.

7. Mullard CV850, this is the winner from my testing EF95 tube. Sounds from Mullard CV850 is great. I choose it because it has great vocal, vocal in this tube is very very good, more soul, singer sing in front of you, no harsh when singer scream. Bass more control too.
