Quality of Cary SLP-74

I am looking to purchase a used Cary SLP74. Can someone out there get me the 411 on this tube preamp? I am switching from Adcom GFP 750 ss pre which i liked but....want to go tube and I am considering used Cary or newer Rogue Metis....or something like that. Both are good based on my research ..will be matching with SS amp, Snell K-7 or older Mcintosh speakers which have been reworked. I listen to a a mix of vinyl and cds. Any advice would be appreciated.
