I'll second jaybo's recommendation for Yamaha and Harman Kardon as I think they will meet your price/features requirements. I like the RX-797 from Yamaha based on auditions and I have owned a Harman Kardon HK3375 for six years and it has given me solid service so I think the current HK's like the 3490 would be a good choice. I particularly like the amp section in Harman's receivers and mine has done a good job driving several bookshelf speakers I have owned. Both brands are 4 ohm capable so your ELS3's should present no problems in that area. Good luck!
