plz suggest a tube preamp to match Parasound A21 amp

Hi, I'd like to add some tube attitude to the signal entering my Parasound A21 amp. Plz suggest decent tube preamp under $2,500...New or used, but no 20-30 years old, vintage stuff plz. Fully balanced design is preferred. Combined XLR / RCA inputs/outputs are necessary. Recently tried Schiit Freya Plus, but didn't like it due to weird volume control function and delayed start. Tnx.
