Amp recommendation


I’m looking for a recommendation for an amp to use with a pair of Acoustic Research AR-91’s. I’ve read that they are power hungry but I need a little direction. This will strictly be for 2 channel use, a mix of CDs and vinyl. The room is roughly 10x15 and listening distance will be fairly close. Current equiptment includes an Arcam 300 and a newer low-end Onkyo. Do I start from scratch or add an amp to the Arcam? 

Thanks

I would go with the highest power integrated you can find for 1500.  I see a few used Hegels here which may be just the ticket.
These speakers are 87 db,  so they could run on 50 watts or so,  the problem is that they are 4 ohm and dip below that, so they will need an amp capable of producing some decent current. Even though the Arcam is 120 watts,  it has a poor power supply and does not produce current well.  I'd look at some thing that greatly increased its power from 8 ohms going to 4 ohms.  Its not a tell all, but it is a good indicator that an amp can produce the current needed for a power hungry speaker.
