Replacing Vintage Spendors is not as easy as I thought


I have a pair of 1989 era Spendor SP1 s and was thinking of updating them as I have heard of the vastly improved technology and materials used by current speaker manufacturers.  So off I have been listening to new speakers, many of which come advertised as natural sounding, or neutral etc. My search has been a bit constrained by my Leben tube amp which is a modest 32 watts. I have heard Harbeth, Aerial Acoustic, Devore, new Spendors, Totem and a few other brands all of which lack the natural vocal qualities of my SP1s.  Some are more dynamic but at the expense of more fatiguing treble.  I have limited my search to the 5000-7500 range but am coming up empty handed.  I am sure if I was ready to spend 15,000 +  I could find a good upgrade, but college tuitions preclude such an expenditure.  Anyone out there with any suggestions?
Thanks

I would be auditioning Audio Note speakers--I have never heard of anyone complaining about too much treble response with their speakers and they are quite easy to drive so they work with a wide variety of amplifiers (by the way, what amps would you be using with your new speakers?  It helps with making recommendations).

Someone who is a fan of old Spendors would also probably like ProAc speakers.  I am particularly fond of their stand-mounted D2 speaker, and their floor-standing speakers with ribbon tweeters (they are more successful at blending ribbons with other drivers than most speaker companies that try to do this trick).
Agree on Proac ribbons. The first ones I've had zero fatigue with.  AN (their more expensive ones with all silver caps and wiring) were musical in the way an FM car radio is/was.  They just didn't move me.  I like the Harbeth's better, but I like VAndy and then Proac better than the top AN speakers.  Again, this is why it's so subjective ...
I like the Harbeth's too, and they certainly do have some similarity in sound to Spendor vintage speakers.  For me, the slight hardness/sibilance in the upper midrange/treble region in all of their speakers, except the 40.2's, is a little bit of an issue, but, this adds a little bit of zip and liveliness to the sound so that might be a plus to someone else.  I feel the same way about Tannoy speakers--just a bit too much hardness.  That is why I prefer ProAc and Audio Note.

I on't know what are the current prices on Shahinian speakers, but that is another line that is easy to listen to and is not excessively bright.
There are some members here that sold their speakers and regret it .If you are ststisfy with your Spendors I don't see any reason to replace them.
I agree with itzhak1969.  If you enjoy your Spendors, why make the change?  Have you tried a little tube rolling with your Leben?  It might give your speakers a nice tune up.
