I bought a TT--Need a phonopre


OK, I did it, I bought a music hall mmf 5.1 with a goldring1012GX MM cart. My first TT in 30 years. I am going to buy a phonopre tomorrow and I want to spend no more then $700.00 new or used. What should I get? I listen mostly to jazz.

Thanks to everyone for all the imput and time!! Lots of great ideas. I think I am going to just PICK one unit and see where I go. I don't think there is another way to do this. I have gone through this process with other pieces of equipment and have found there is no short cut, but that's what keeps it fun and interesting. Thanks again to everyone for there insight.

The SimAudio LP3 is a great phono stage for about that money, and I bet you can make it sound even better by running it off a battery.
Try the Project Tube Boxes. They're reasonable priced - $450 & $700 respectively and they sound really good. I've got the cheap one with stock tubes and I'm very happy with it. It doesn't have any controls other than switching between MM and MC and I've never wanted for anything with it.
At $700, my choice would be a used Audio Research PH-3. It's an incredibly good phono stage for the money.
