Ambient noise when listening to open back headphones can instantly kill the bass, even with closed back it has an impact. its why you will find a lot of earphones have a boosted bass to compensate.
Maybe they should do these shows with dedicated soundproof cubicles
Show conditions are normally more or less absolutely useless for hearing how good or not good a new product sounds.
I have not been to an audio show for many years for that reason.
I was tempted to visit Canjam in Singapore since I was nearby, but I stayed on the beach a couple of days more instead.
I would even say that most shops are too noisy to do any serious listening apart from the fact that they almost invariably play unsuitable low res material anyway.
In Asia where I spend my winters there are only a few shops that will allow you to listen under reasonably good conditions.
I have yet to find one with sound isolated cubicles there.
When I auditioned DAVE I did get a room for myself for a couple of hours though. And one of the dedicated headphones dealers in KL has a storage room where one can turn of the A/C and listen in peace and quiet away from all ambient noise.
Try listening to a symphonic ppp even via headphones with A/C on.
Jaben in Singapore is very noisy and they often keep their door open with all the noise from the surrounding mall seeping in, to attract customers.
They do not offer any real quality listening facilities at all.
There are a couple of dealers in Stockholm that have listening booths for headphones.
Serious dealers let you audition at home before buying a product.
I have had lots of amps,speakers and cabling and headphones and such at home for weeks before deciding on what I want to keep sometimes.
Having said all this I am of course still curious enough to check if any of the dealers at the Adelphi has got HUGO 2 for auditioning when I get back there in a few days.
