Introduction

There are few names that are both as well known and associated with high-end as Rotel. They have a reputation for quality and power and great aesthetics. At only 100 watts, I couldn't say that the RMB-1085 was a huge improvement over the internal amps of my receiver with my 8 ohm speakers. It does have an undeniable cool factor and plenty of power if your current amplification needs are inadequate or your speakers have lower impedance and are giving your current amp/receiver trouble. If you are looking to beef up your home theater or just have a touch of the upgrade bug, the RMB-1085 is a little firecracker of an amp that might be what you've been looking for.
