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.

LOL, I bought a REF110 this spring and had the same surprise.  I ended up buying a LS17SE that is still breaking in.  Sounds amazing though!!

For short term you could run an RCA to balanced cable from the SP9 to Ref.110. If you have a good tech you can upgrade the SP9 way past a MK.111. The phono stage especially will be light years ahead of a Mk.11, the line stage pretty damn good as well. You could run the phono stage from the SP9 into another Pre-Amp if desired.

The best fully balanced Pre. I've heard for the money is the Vincent SA-T8, sublime. Compares to many Pre's 2 to 3 times it's cost. No phono stage though. Have just got a Doge 8, has balanced outs, but not fully balanced. You'd need to roll the tubes. The line stage sounds promising. I havn't used the built in phono stage yet. By all reports the MM stage is very good, but the MC is crap. What cart are you running?

Don't be too harsh on ARC, the SP 9 is an old "entry level" (for them) unit, built and sold back before ARC went all balanced with their equipment--that didn't start till they brought out the LS 5 (a terrific sounding line stage, by the way).  I'd go with later ARC preamps for the long term--the LS 16 was their first full-function preamp that had balanced outputs, as I recall, but it will sound different than the SP 9, which was less "tubey".  For the short term, initforthemusic has some good ideas, you might also ask ARC or a good tech if there's a way to give the SP 9 true or faux balanced outputs for your purposes.
