I wanted a replacement AVR for a very old one preferably Denon and a match for my current flagship model a few years old which would replace the very old AVR and would replace it. My normal store could not help and I had seen Peter Tyson online many times and decided to give them a try. I initially wanted to buy over the phone but was advised online was quicker and easier. So it turned out to be, I ordered before the days deadline and the Denon AVR-X6400 arrived in NE Scotland the following morning 11am. Really appreciate the good advice, competitive pricing, additional included goodies and above all excellent service. Surprisingly the AVR-X6400 is in most respects the same as the two flagship models above it other than the number of active amplifiers. I will be dealing with Peter Tyson again I really do appreciate excellent service
