old newbie

Hi to all. Sorry for the length but here goes, Been out of the game awhile,kids,braces,college. Get the picture. Anyhow just picked up a pair of mint vandersteen 1cis. This is my second pair owned 1bs yrs ago. They sound better than the 1bs but I believe their being held back by my old gear,adcom gtp400 tuner/pre and 535II amp and rotel rcd 955ax cdp. Thought about a liin classik or should i go the integrated amp cdp route. budget is 1000-1200. Tuner is not a concern at this time. Im thinking used, more bang for the buck. Thanks for any and all suggestions.
