shure ksm 44 vs neumann TLM 49

I have a Shure KSM 44 mic. $799.97

I am thinking about a Neumann TLM 49. $1,499.00

My preamp is a Vintech x73i



Here is my question. Will I hear a noticeable improvement in recording to justify the extra expense? Thank-you 8)



P.S. sorry didn't see the other thread I could have posted under.
