Rotel RMB-1555 Five Channel Amplifier 

The RMB-1555 is a highly prolific piece of high-power technology and is ideal for the high-end home cinema of multiroom music system set-ups. The machine utilises a hefty 120 watts of power per channel, into 8 ohms when all five channels are driven to their full output. That means even some of the more demanding speakers on the market are pushed to their very best performance.

The RMB-1555's unbeatable performance is all down to it's 'Balanced Design Concept', developed by Rotel. For decades now, Rotel's power amplifier catalogue has been revered by the hifi industry for decades, thanks to Rotel's 'less is more' philosophy, which enhances and underlines the simple approach to developing audiophile amplifiers. This Balanced Design Concept utilises specially picked components, which when used in conjunction with optimised and symmetrical signal paths and critical evaluation to assess and fine-tune performance throughout the entire process of designing the unit. This creates an absolutely excellent product. 

The RMB-1555 makes use of discrete output transistors, these have a higher thermal stability than standard transistors and do not have the same restraints as other methods that can be found in integrated circuit relatives.
