Audio Note M3 Pre- Amp, Valve upgrade


I have been comparing my AN M3 Pre to some other highly regarded Pre's & it seems to be a bit lean.
It has 2 x Jan Phillips 5687wb's (I suspect they are the culprits) 1 x EH 6BM8 & 1 Unbranded 6X5.
Can any experienced Audiophile offer a valve upgrade suggestion for the M3?

Many Thanks

My M3 is the Black Kit Pre with Noble Volume Pot & selector,
Sounds deatiled, but a little thin, doesn't throw as wide an image as some other Tube Pre's

Thanks for the advise.
