Try befreo you buy but I think adding in a tube preamp will give you what you are looking for. I replaced my Bryston BP25(SS) with a Rogue 66 tube preamp and it has made the largest difference in a positive way with both my former speakers - Acoustat hybrids and 1.5 Maggies (current speakers)
Tube Pre-amp beneficial?
Will a tube pre-amp "warm-up" my Martin Logan SL-3s if I am running a SS amp (Sunfire)? Or, do I need tubes throughout? I am currently using an Adcom GFP-565 in bypass mode, and I would like to upgrade the pre (staying under $1000) and add a remote, any recommendations from people with similar equipment would be appreciated.
