So an extended home demonstration / trial is the only way to accurately judge a complete hi-fi system or component.
I have lost count of the amount of times i have read how a purchase is made, and, initially the buyer is overjoyed with their purchase.
However after a week or so this joy turns to anguish as they suddenly notice aspects they don't like and did not notice upon first listening resulting in the item being returned...
Is this because the component purchased has changed sound quality wise via "burn-in" ?
Or has the initial "excitement" of the new purchase simply gone which allows a true assessment of the purchase to then be made ?
Essentially, yes. A complete system may be tricky, but anyone interested in say, replacing their amplifier, isn’t going to get any meaningful feedback from listening to an amp or two (other than a direct comparison) in an unfamiliar room, potentially on unfamiliar speakers, and maybe even with different cables and source. You HAVE TO hear an amplifier with the speakers they will be driving, not necessarily in your own room, but if you take along your own amplifier you should get a meaningful comparison between it and your intended amplifier. Of course, differences will be more apparent at home because you know your own listening space. And speakers really have to be heard in your room. Speakers are the only product in the system that interacts with the room, so you have to get feedback on that aspect - it’s one of the two main aspects, along with getting the right amp/speaker match.
Borrowing a demo unit initially negates the initial burn in period of new products. Burn in seems to affect some products more than others, so it’s knowing which ones aren’t going to change much, and which ones really come out of their shell.
After the excitement of a new toy has worn off, if the user is then feeling less than overwhelmed with the item, it’s usually down to a few things. Either it’s a product they saw on a deal and they just bought it blind with virtually zero research, or they fell foul of a good salesman and it’s not really the product they needed. Either way, it could be that there’s some mismatch in the system, or the speakers just aren’t right for the room (usually the case with speakers). And it all comes down to lack of research. I don’t mean garnering opinions, as opinions are like the proverbial butt hole, and many opinions come from others using mismatched systems or without the real experience to be offering that opinion. I don’t mean that to sound condescending, but I t’s like someone buying a car - which car shall I buy? Oh, I like the look of that Peugeot, and Which? gave it five stars so I’ll just buy that. Plus, they get a deal on it too. Score. They rave about it online saying it’s an amazing car and trying to get other people to buy it because it’s so good - with ZERO experience of any other car available in its price range. Is it a valid opinion? Valid recommendation? All they can say is that they’re happy with the car, nothing else.
Everyone can read reviews until they’re blue in the face, but it all comes down to your own research, and it doesn’t need to be anything extensive or hugely time consuming. All it takes is a day out to a dealer or two and listen to some products. The most interesting sounding one, the one that seems to be the answer to your needs, ask to take it home to try it out. Even if for a few days, you’ll be able to form an opinion on how it performs in your own system. Maybe it doesn’t work as well as you’d hoped, maybe it’s a little bit forward sounding, but from your demos, you recall another amp that was a little more laid back - try that one. It may be more time than you’re willing to spend, but it could save you time on just buying one based on reviews only to find that the negatives that aren’t mentioned don’t suit you, and you have to arrange for it to go back, then look for another one, go through the whole process again. Compare that to a day out and making the right decision in the first place. What’s on day for a purchase that could be costing £2,000, £3,000, maybe more.
