A topic I just thought I'd bring up, as I've been reviving my own modest hi-fi system (mostly stuff bought in the 90s, plus an 80s tuner and 70s turntable) which has not been getting the use it should. I've recently got a Cambridge Audio Dacmagic 100, which allows me to get very good quality from my digital music files and plug my laptop into the hi-fi system - it's great, the improvement in quality from even mp3s is very noticeable. I can also use it to improve the sound from the cd and minidisc players.
I've also bought a Cambridge Audio Dacmagic XS, which is a small dongle kind of dac/headphone amp thing that you can plug into the USB of a computer, and it bypasses the computer's not very good digital to analog circuitry, replaced with really good stuff, and you can plug your headphones in to listen in high quality.
Another recent purchase is a pair of Philips Fidelio X2 headphones - the most I've ever spent on headphones, but the sound is superb I have to say. Anyhow, spending money I can ill afford, oh dear, I will have to go on an austerity drive now...
At the moment I'm setting up the hi-fi in a small room which will become a "man cave", and also I'll have the guitar gear in there (at least as much of it as will fit - I have too many guitars), and it should make a good practice space.
Anyone else got a bit of a hi-fi bug?
