Phonostages with Adjustable Curves, the Concise List

If you play lots of records made before the RIAA curve became the standard, such flexibility is useful, even necessary for historical archiving. Otherwise, it only introduces extra switches, components and solder joints that can degrade SQ. I once rebuilt a Quad 22 preamp, which offered several curves — I never used them so I stripped them out. I ended up with almost a meter of wire, in many little 1- and 2-inch lengths, plus several switches, little caps and resistors, left over on my bench — and a far better sounding preamp.

Hadley 621: curves for RIAA, LP (“Old Columbia”), and 78. Also Marantz 7C and 7T.

I am indeed asking about photostages/preamps that offer different curves than RIAA.  I have some European pressings from some of the great orchestras and conductors of the 20th century that frankly sound awful with a standard RIAA curve...no bass, ear piercing cymbals, ect....as an avid classical music fan who seeks out artists of this era as examples to get us closer to the composer's intention (like when you can get an interpretation or student or two away from the original), I would like to be able to make these albums "listenable".  Thanks for your continued options 'Goners!

Yes, @phomchick...I found that particular thread however there was little mention of devices that fit the bill...was hoping to get some more concise examples of equipment that would perform under these circumstances.
