phono/preamp analog front end


I have a great, older  analog system...Oracle/Graham 1.5t Ceramic/Ortofon A95/Classe DR-6(modified/refurbished)/Threshold 4000 (modified)/Von Schweikert VR4.5 Silver with all nice power cords/interconnects.....considering upgrading preamp...used vs  new, looking to spend about $5K....could stick with SS, get used Pass Labs XP-15/X2.5 for <$5k....never ventured into tubes.....no convenient stores for me to go to....any thoughts?

@sandthemall: I agree with you! I can't think of a way that resistive/capacitive loading can effect the stiffness (Young's Modulus) of a cantilever! 
He doesn’t refer to the actual stiffness of the cantilever, but to the electromagnetic damping effect the loading applies, which affects the compliance of the moving system, I think...
@testpilot 

The Herron uses external loading plugs, although the designer feels it sounds best unloaded.

Interestingly I have always found my Herron to sound better with loading - and in fact at a loading usually very close to cartridge manufacturer recommendations.  I know some stages like Sutherland's Little LOCO uses transimpedance amplification so you never dial in the loading using a switch but there is still loading.  And then you have some Boulder stages that have fixed loading but with no switches.  It seems that @atmasphere is saying that only phono stages they don't present any cartridge load are properly designed...I'm still not totally understanding this, especially since the cart manufactures recommend a load.
I like the Tavish design preamps....I paired the classic with jensen transformer and running a hana el. The adagio comes fully equipped with the Jensen’s for more money....I think its Herb’s reference phono preamp....they are tube preamps made in NY USA....
