Rotel's amps are pretty good bang for the buck. What about it do you not like?
Some thoughts of amps with good price to performance ratios include McCormack (DNA 0.5, 1, 125), Monarchy (70, SE-100), Parasound, some of the older Musical Fidelity (A3cr, A3.2cr), van alstine, Conrad Johnson Sonographe, Marsh (A200,400).
We can provide a better answer if you have some idea of the change in sound that you would like to achieve, as well as what speakers you are planning on using and, as mentioned in the previous post, information about your room.
