Personally I want to simplify my system and reduce my box count & recently moved from Boulder separates to a Vitus SIA-025. The Vitus' linestage is made from one single buffer module which is also used in the Vitus SL-102.. so..really good. The SIA-025 was upgraded in early 2012 with most focus on the modules in both pre and power amp sections which resulted in higher resolution and better power handling. It also comes with a very nice programmable remote. As for power and authority, well the Vitus is surprisingly powerful and so no problems there. Another integrated that comes to mind is the Boulder 865 which has a very good preamp section imho.
