I have many CD's that have a quality variance from song to song as well . Cd's , especially classic rock , are not very well done . That's just the way that it is .
I have found that tubed components will help with this issue , the more the better . And I do have rather resolving speakers .
If I were you I would change the amp to a tubed integrated . Pick up a used one here and try it out . The worst that could happen is that you loose a couple of bucks on the resale and shipping charges ! Or you may like what you hear and keep it . Just a thought .
Good luck .
