A new review site starts with a few products that measure well. However as it digs through the rest of the market it finds more and more products of similar competitiveness. (Yay capitalism) The personal perspective however may not catch up. Or, with a site that produces one review every two days, it is difficult just to comb through the data.
Hence a recommendation is to put price and date info below the SINAD numbers chart.
I'm not one who buys into SINAD telling the whole story in these evals. So, perhaps the other features round it out enough to put it in the "buy now" category. Seemed like a solid performer overall, though I hate those top hat knobs, had 'em on a few Gibby's, they're impossible to grip quickly, or roll with your pinky.
--OR--
Because Amir is getting soft?
Customer's requirement vs supply plays a big role. I like to use the iLoud as an example, because if judging based on performance/price alone, there are many (bigger) speakers that perform much better, even if only in terms of bass frequency range but that is very important in overall performance.
However if we're talking about performance from a size no bigger than a soda can, then nothing comes close. So depending on situation, it can be "meh" or "there's no alternative".
So what does Burson FUN offer? Class A output stage (yay no crossover distortion) and you can use any class AB op-amp you want (yay crossover distortion), even those not meant for driving headphones and still get good sound out of it.
