I have to recommend the MC352 you will not be sorry, it is super fast,very big wide soundstage and is slightly warm with awesome detail and slam! Plus it never has any issues, it just always is very reliable. I however recommend a tube preamp and it dosent have to be McIntosh. Your audio research 260ohm output will work fine with the RCA (20k) input on the MC352.The Balanced input on the MC352 is 40,000 so you could pick a preamp with BAL outs and low output and it will really mate well. I hope you make the right choice as you can waste a lot of $$ in this hobby trying to get your sound the way you want it. Happy listening.
