http://www.zzounds.com/item--BEHDEQ2496 Hope this link works... I just got a couple of Squeezeboxes....the two items don't necessarily go together....but I was reading on the Slimserver forum and a couple of people said they used one of these devices as an equalizer and to set up their listening room...... It's really not that expensive, but I have to admit...I don't know exactly what it is? Is it just a good equalizer or more than that? What else would you use it for? Thanks.
