Hello. Recently I bought elac's for 140$ and now I am searching for a matching amplifier. I would prefer used or vintage one. My budget is about 250$. I was looking at Marantz PM5005 or PM6003, Technics SU-Z2, Rotel RA 970BX or RA 413, ITT 8033, Yamaha R-S500, NAD c350 or c326bee, Cambridge Audio Topaz SR10 V2 or Topaz AM10, Denon PMA 980R or PMA 860 or PMA 710AE but I have no idea if any of those will sound good with elac's. Can someone give me some recommendations on any of those or something different that will sound good at this price point?
