Altec Valencia/Altec 604/LM 755 or O/96?

[Sancho22]

Hi everybody. I am aware o fthe posts about the match of o/96 and Shindo, Valencia and Shindo, but less so of 604 or the LM 755.

I could potentially get a very nice pair of 604 in a 620 9 cuft custom cabinet with Gret Plains Audio drivers for half of the price of used o/96 but twice the price of the Valencias (or 3 times if I find cheaper a pair of Valencias).
Which one would you guys think is best getting?

I have Shindo Montilel and Aurieges as well as Almarro 318b. Planning to get some McIntosh amps, MC30 or 225 or maybe 240 in the future.

I did not see much of published comparison between LM 755 and O/96 - any experience?
