I'd suggest looking at Ascend Acoustics' Sierra-2 speakers personally (having several other models of theirs). Philharmonics are on my short list, probably Salk as well. Even for music I'd add a sub(s) to them and if going just 2-ch an integrated amp or receiver with bass management. Is the $4000 for speakers alone or everything, speakers/sub and amp? I've been using my SL1200mk2 for over 30 years....
