Looking for an used, inexpensive pre amp


Currently using a cheap but fairly nice sounding Dayton T120 D class amp.  Not enough inputs.  I would like to find a pre amp to use with this amp and perhaps at some point, if I can find the money, I can buy a power amplifier to replace the Dayton.

Figure my budget to be under $200 right now.  Looks like plenty of older inexpensive Solid State pre amps are available on Ebay.  

Any ideas what I should look for when buying a preamp?  I've only used Integrated amplifiers up to this point.

Look for a Hafler DH110.  It'll be in your budget and will do a most excellent job.  I like them much better than anything Adcom ever made, but that's just me.
  •   Hi , how about the Schiit Jotenheim ? $ 399 , I know it’s twice $200. Add a DAC for a hundred . It sounds great and really shines when you add a balanced cable to your headphones . My point is this , Great little pre , Good DAC and Outstanding balanced headphone amp ( maybe the best ), at its price point . When you move on , as we all do , it’s a great little headphone DAC/amp to pair with your laptop in the bedroom or the hotel room ! Food for thought . Stay hungry my friend . Mike .
Older Rotel RC preamps can be found on Ebay for ~$200+.  I have owned the 1070 series and they are pretty solid for the money.  There Power amps are on there as well.
