Lintone Audio, Gateshead. I always dealt with David Baker, who is a great guy, very knowledgeable, and was always happy to let me spend many hours in the demo room without ever pushing for a sale. He now has his own company - Audio Therapy, Newcastle.
Rayleigh Hifi, Rayleigh were my local dealer for many years in the 80s/90s until I moved up north. Always great service and support.
