OP, here are the common means to integrate your TT:
1. phono preamp>line preamp, which does not include phono preamp>power amp
2. phono preamp>integrated amp
3. integrated amp, which includes phono preamp
4. line preamp, which includes phono preamp>power amp
if you want to use your power amp you must select #1 or #4; but, either of these means to pleasure is expensive. The least expensive route will be door #3, perhaps, a Marantz integrated amp, all include a phono preamp. They run from $500 to $1000 and all but the least expensive have both analog and digital inputs.
