There's no substitute for using your senses - eyes or ears. Good  
dealers are difficult to come by nowadays. Two channel hi-fi is much  
more of a niche market now, with many people going to 5.1 or 7.1  
systems with lots of bass boost.

I've collected my hi-fi over 30 years, having spent my younger days  
selling the stuff in a shop with a guy called Ken Kessler. As a  
result, I'm a vinyl, valves (tubes) and efficient speakers man.  
there's no such thing as a perfect hi-fi component or system. The room  
in which you listen is very important too; you just have to go to  
enough live music events (classical, jazz or rock) to appreciate how  
some venues are acoustically terrible.

I've spent a lot of money on my turntable (Platine Verdier/ Schroeder  
Model 2 arm and Allaerts MC1B cartridge) and I'm very happy now. So  
now I just spend my money on records. It's just like cameras - you buy  
the kit you want to use and then you should take lots of pictures.
