Vintage amp and Hi-end speakers-good match

My Coincident Conquests "sing" when run with my 1958 Pilot tube system (integrated, mpx, tuner) and Vintage Marantz turntable. All that is new are the speakers, Nordost interconnects, adcom line conditioner and ortofon cartridge.

I have a vintage sansui au-717 that sounds pretty good so I would say yes, as long as you compare it's sound to good midfi amps on the market. I have an onkyo m-504 amp which is older midfi amp and it sounds even better. If I compare them to my other two hi-end amps they don't do as well as you would expect. Now if you listen to a vintage high-end amp you could find something that would sound very good with most any speaker that they could drive.

Thanks for the responses. I have another question. How is the Sansui AU-20000 compare to high-end amplifier in to driving expensive speakers.? Thanks again.
