As I sit here rocking to Mussorgsky's Pictures At An Exhibition you know which route I'd go, rebbi.
The thing is if your enjoying your system with the Krell, buying it would be a good way to go as well.
After a year of looking into a new amp I went with the Nuprime IDA-16 because of the excellent price/performance potential and the 45 day trial period.
After living with it now for eight months I believe it to be a fantastic value; When you consider 200 watts of amplification combined with a great dac and excellent functionality (it has one of the best volume controls I've used).
Good luck in your search, rebbi.
