I have a pair of 1977 Klipsch Cornwall speakers with the Bob Crites cornscalla midrange horns. Prior to adding the corscalla midrange horns, I drove the Cornwalls with a Cary preamp and a pair of Cary SET 8 WPC amplifiers. This had a very nice sound but was lacking in the midrange. Then I upgraded the Cornwalls with the Crites midrange horns and crossovers. The Cary SET amps no longer could get these speakers off the ground. I then tried some of my older Pioneer receivers (SX-850, SX-980, ans SX-1080). These drove the Cornwalls much better but sounded just a little on the bright side. Then I got a Marantz 2270 reciver and tried it. Wow. The Cornwalls sounded just right. The midrange and bass opened up nicely. I also picked up a Marantz 2252B and a 2285B. The 2252B and the 2285B have more detail than the 2270 does, but the 2270 has a nicer midrange and is a tad more musical than the other Marantz receivers that I own. It just amazes me how good these 30 - 40 year old receivers sound yet. To my knowledge, these receivers are all original yet.
