JBL L300 Summit vs. Olympus w/S8R system

As you mentioned Olympus S8R would work with low power amps. Do you have any suggestion. I am useing Jadis JA500 to drive with S8R. I found the mid range density is pretty good and musical. Somebody told me MC240 is the best matching with S8R?? Do you have any idea, pls. let me know

It sounds great with a pair of modified Leak TL-10.1's and amazing with Radford STA-25.

I am not familar with Leak TL10.1's and Radford STA-25. Those are single end?? What about MC-240 compare with single end?? Can anyone give me any suggestion.

I have an L300 system in Apollo cabs that I drive w/ a restored Dynaco ST70 - They work just fine with the Dynaco.
I have an Olympus S8R system in the living room that is driven w/ Two JBL Urei 6260 amps and a 6230 amp w/ an electronic crossover set at 760 and 6500 hz - The olympus system is quite loud - Nearly earsplitting

True, the L-300's are an efficient speaker.
A slight correction DoubleBass, that 4400 Marantz you have/had puts out 125wpc in Stereo if memory serves me correctly (I owned a new one back in the day). Mark
