Have Jeff Rowland Concentra II am I crazy...

Was thinking of using it as a preamp, Getting the Mcintosh 2102 or Vtl st150 amps. To bring that tube sound to Sonus Farber Grand pianos. Thanks for your toughts
I bought one from bizzy bee with all the extras and used EH kt88's. Was a nice integrated but found the bass very loose and boomy, the focus switch didnt help that much. At 30 watts I wouldnt recomend it for a med to large size room.
a'gon member 'the kid' uses a cary sli-80 w/grand pianos & likes it very much. good luck.
Thanks for the responses...will let you know what happens. Still trying to get a hold of an tube amp the use rowland as pre.
