Which used preamp for Halo A21, under $1,000?


Right now, I have an Anthem TLP-1 pre mated to a new Parasound A21. The combo sounds good, but I suspect that the Anthem may be the limiting factor to achieving "great." Suggestions?

Preamp: Anthem TLP-1
Amp: Parasound Halo A21
Disc player: Oppo BDP-105
Turntable: Beogram 8002
Speakers: Alon II

"Hey Dweller. Yep, I know about driving the A21 with the Oppo, however, I listen to enough vinyl to make switching cables to the amp inputs a PITA."

Try it anyway just to see what the differences are. The results may help you pick the right preamp.
Dbxdx5,
My Dodd has a remote.
Also the wooden front face plate. Different from what the site currently
shows. See it in my rack in my two channel system posted here on the
AudiogoN.
used MUSE MODEL 3 is champion at your budget, but hard to find. if you have patience, you can catch it on ebay or here.
