Hello, here we have a pair of MBL 8011AM Mono Blocks.
I have owned these for one year and they sound amazing. These have no issues at all and work perfectly. the only Blemishes are the bent heat sinks on one amp and a Small scrape/dent on the bottom of another heat sink. I got them this way from a reputable dealer who claimed that these dings were done at the CES show. Either way they have performed amazingly and I am moving up the chain. You can find specs on the MBL website. Have original boxes and manuals.
