Accuphase C-200, X, L, V What is the difference?

There's very few Accuphase owners here. Most say they're over priced in the US but those same people have never heard one. My friend is a local dealer so I got a demo E600 integrated years back and I've been away from Agon ever since. I fell off the upgrade wagon for the first time in my life. Good stuff. I wish I could answer your question but I can't. 

The Accuphase museum might have that information. I owned the C-200 many moons ago!

" I owned the C-200 many moons ago! "
so what is your impression  and what dou you have now?

It was a very nice preamp with an abundant amount of features. It’s been 40 + years and I have owned a numerous amount of gear since then. I use all tube gear now! BTW, I also owned the matching P-300 power amp!

I've been looking at the C-200 lately and here's what I've gleaned:

The C-200 came out in 1973.  The X version came out in 1980.  The L version in 1984 and the V version in 1987.

The cosmetics basically stayed the same, but each version changed the internals.

The X version is DC coupled and added a head amp for MC carts.

The L version changed the layout of the internal cards and power supply to be similar to the 280 and added a balanced output.

The V version changed the internal cards again, added 2 balanced inputs, but dropped the 2nd phono input and the front phono input.

The specs for the 80s versions are very similar, but the measurements they put in the brochures definitely look different.
