However, the AV.com extended warranty scheme provides an enhanced service, and is designed to offer a higher level of protection than many 'free' warranties offered by some retailers and manufacturers.
The highlights of this enhanced warranty service are:
Please note that this extended warranty is currently only available on products sold within the UK, EU or EEA, and is subject to the terms and conditions as detailed on the extended warranty certificate provided.
For customers in outlying areas of the country, the price of the Extended Warranty may be marginally higher, due to the potential for higher collection and redelivery transport costs.
This enhanced warranty is in addition to the standard AV.com and manufacturer warranty policies, and the AV.com terms and conditions of trade. No statement or condition of sale contained within these terms affects or restricts your statutory rights as defined under the Consumer Contracts Regulation 2014.

Key Features
The Topping Pre Series B100 Class AB Power Amplifier is a mono amp built for high-fidelity systems, featuring the T'ang-ku-la Module which uses a brand-new three-stage feedback circuit to minimise distortion and enhance dynamic range to 151dB. This makes it a strong choice for powering premium passive speakers. It is capable of delivering 100W at four-ohms and 83W at eight, ensuring dependable performance across different speaker loads.
For connectivity, the B100 features a combo XLR/TRS input alongside an RCA input, making it easy to pair with a wide range of preamps and DACs. It also features a 12V trigger input, meaning seamless power syncing with a second B100 and connected pre-amp equipment, adding convenience to your system. High-quality speaker terminals ensure a secure connection, while three selectable gain settings (low, medium, and high) let you fine-tune the output to suit your setup.
