Love watching things like that. Used to have access at work to very high end recording and audiophile equipment though and honestly, past a certain point you really can't tell the difference and are just paying thousands for the sake of it. I have found the optimum price for separates to be around the £500 pound mark each. After that with my hearing at least I struggle to hear a difference. I use a Rega Planer turntable and love it.
