Willsenton R8 Tubed Integrated Amplifier

The Excellent R8 integrated Amplifier Provides enough power (Especially with the KT88) to drive almost all speakers and has been tested with speakers up to 86 dB.

The amplifier also comes with a headphone out for those headphone lovers.

This version has the KT 88 tubes for an excellent grip and base response and the Preamp tubes have been retained to the Willsenton to keep that sweet tube flavour.

The Cage has also been included as an extra for customers who buy from Hifimart!
