The Eagle 2A (120 watts/channel)or the very rare Kenwood L09M (300 watt monoblock)would be great choices. Or the Audio Research D-350, which turns up on ebay from time to time. These are all bass amps. Or, believe it or not, the Bose 1801. Mark Levinson used the Bose on the Hartley woofers in the HQD system before he had amps of his own.
