Integrated amp shutting down

I had to downsize after the divorce and lost my beloved system, BWN803/Classe CA 300 amp, and Classe pre-amp. I picked up a cheap set of Vandersteen 2cis and am trying to run them with a Harmon Kardon AVR 500, which is really a surround sound processor with 80watts. The thing cuts out and shuts down with any volume. I suppose that means, the speakers are trying to pull more power than it can supply?
If that is so, wonder if you guys could recommend a good, inexpensive integrated amp, ss or tubes?
thanks,
