I've had an interest in HiFi since I was quite young - my grandparents had a lovely Quad setup (ESL57s, 33/303 and a Thorens deck) I used to listen to most Sundays. I've spend the last 30 or so years trying to build a system to replicate the sound without the hassle of living with ESLs. My first system (purchased from Richer Sounds with the proceeds from a summer job spent working in a pub kitchen and consisting of Cambridge audio amp/Eltac speakers) has been steadily upgraded over the years and I'm now living with Harbeth SHl5+ speakers, quad 99/909 amp and a Michell Gyrodec and I couldn't be happier with the sound.
In terms of what to listen to, it's probably a case of 'a little bit of everything' although recently I've become increasingly interested in Jazz, piano trios in particular. I've also recently discovered the London Jazz Collector blog and reading through past posts has certainly provided a lot of inspiration for things to listen to/discover.
