its interesting to go to hifi conventions,
I think its a must do for anyone interested in audio reproduction. However you must be prepared for a shock that you might not like HIFI.
Also just how bad some equipment can sound and the different opinions of others things they like and dislike.
I have said this before, I think some HIFI is like perfume the bottle looks great!
The trouble with HIFI is its all about opinions and what one person wants another hates.
During a HIFI show some time ago I remember being un-impressed with a lot of the equipment and walking into a room with some refurbished PYE amps and instantly wanting one

the reason was it was relaxing like a breath of fresh air after listening to the hundreds of rooms of equipment.
One of the most impressive systems I have listened to some time ago was not tube (shock horror) using a counterpoint DAC with Krell amplification and magnepan speakers running a sub woofer that made a church organ materialise in the room all quite spectacular. I had a long listen to Ongaku and the Gaku-on etc..all very interesting but you know when you get that ermm moment..
I'm not convinced these days something seems to be missing.
Personally I like small equipment its not a case of MIDFI etc its the divide between practical and sound. With formats changing so fast its hard to know where to begin. Years ago I got disillusioned with HIFI and scrapped all of it and bought a reasonably good MIDFI. It ran for a few years and got ditched again

I have watched people I know change expensive equipment like buying sweets. Then they listen to something else and their equipment suddenly becomes rubbish again. I believe the reason is that not much equipment can play different types of music well and when people change what they listen to the equipment can't cope. So the MIDFI argument may have some merit if it can play most music reasonably well but nothing fantastic.
