The DK were over-hyped when they first came out as the best integrated amp ever beats and competes with separates at 3 to 5 times its cost. That's not true but it is a very good integrated. Then LSA bought out DK and IMO made the comapny stronger and improved their product line across the board. Their Signature and Statement models have received, from top line reviewers, high praise.
But like any audio component it is about personal taste and budget. I once had the DK MKII and really liked it but got the bug and decided to upgrade to the Audia Flight Two integrated. I kept the Audia Flight for about 3 month and sold it because I really missed my DK.
I bought a new Moon Audio Integrated made by LSA. I had no problems selling my DK integrated. I love the sound and probally will keep this for awhile.
Resale comes into play if you don't like the sound but the Moon new for $2400, which is better than the LSA Standard, is a great buy. The quality and the workmanship are first rate.
I believe it is a great deal others might disagree but it works for me.
