Preamp for audio research ref110

Hi, just purchased an arc ref110. My current preamp is an arc sp9 mkii. Unfortunately it doesn't have balanced outputs (why do they sell them like that? given that most of their amps need balanced). I am looking for a short term and long term solution. For the short term I would like to at least test the amp with a minimum of investment (as I need to wait until the purse reloads). So my questions are: is there anyway to use what I have for a while? And what would be a good longer term solution hopefully under 3k. And by the way I use records so I need a phono solution. Thank you all in advance.
