I used to drive my system with a Classe 300 amp with Jadis tube pre up front. The mix was unexpectedly successful. Great slam and speed with a bit of added imaging and airiness. A friend also enjoyed a CAT pre with a solid state amp ( don't recall mfg.). I do not believe combinations, of any sort, can be impugned without first listening. Some threads and reviews have dissuaded the mixing of interconnects, espousing one brand link the entire system. This may hold true with certain manufacturer cables within certain systems, but I have found nice synergy in combinations. Best to listen, then decide.
