Crisp sounding tubes for Modwright 5400ES


I recently upgraded from a Modwright 9100ES to a Modwright 5400ES. While there were improvements, the richer mid-range and more powerful bottom end of the 5400ES tipped my previously balanced sounding system into one sounding a bit overly polite with a lack if crispness in the top end.
Can anyone advise me on what tubes (output & rectifier) and power cables to chose so as to brighten the top-end.
Grateful for your advise.

If you are looking for more detail, deeper/wider soundstage, much lower floor noise, sharper images and flat out overall better sound? Try the new Synergistic fuses, my Supreme Hi-Fi fuses doesn't come close to the level of performance these things bring right out of the box.

It's like switching from the Mullard 5AR4 to the Create, and could be even more dramatic. 30 days to try for yourself and they are not going back...
Forgot to mention that the Hi-Fi fuses are more warmer and fatter in their presentation, which can come off as slow and congested in some systems.
wig where did you put the fuse? in the power supply, the transport, or both?
