Got the idea to see if there is any integrated that is known for having as good preamp in it? I could use it for the pure with my Mac mc250 but also have as a backup for when I want a change or need backup? Current premium is an old Acurus RL11 and also have a Luminous Audio Axiom. Figure$1500 max used.
I recommend that you just get a preamp and not an integrated. Its very difficult to make an inexpensive active preamp. If you put the $1500 towards a good used preamp, you should be able to get something that sounds very good.
