Re: Hardware to room play the collection

 

Hello All - 

I am very happy with EAC and my audio systems and just keep an eye on
the forum for anything that grabs my attention. The recent debates on
improvements to systems have piqued my interest so I looked up Peter
Belt to find that he is still in business and selling his snake oil
"treatments", some of which sound rather Tolkeinesque to me. There was
some debate in the UK audio world about 20 years ago and his methods
were debunked as nonsense. 

If you want a chuckle have a look here:

All the best, 

Ian,

> Could not agree more with Gerry on the voodoo factor of Audiophile HiFi. The amount of money some people are prepared to put into extremely questionable equipment has always fascinated me. Examples include £5,500 for a one-metre mains cord to supply AC from the wall to the amp; special paint to paint the circumference of CDs so that they sound better, small plastic spacers shaped like powerline towers intended to suspend speaker cable at a certain distance above the floor and small pieces of wood (£1,500 each) that if placed on top of your speakers are supposed to improve the sound. Once you reach a certain quality of equipment, I would argue that the best investment you can make in improving your sound would be to change your room layout, furnishings, carpets, curtains etc. - that wil
 l have an audible effect on your listening enjoyment.

When they __can__ demonstrate a perceptible difference, it pretty much always seems to be the case that they've simply altered the sound in a way they like, which is fine, but if you do that, now you're an artist, changing the sound that Miles Davis or Kanye West intended. Ultimately, the 'audiophile' community of today seems to be primarily about tribalism, and so the most important thing is to elevate their ethos above the unwashed masses. That's why any form of 'proof' of claims is derided as unimportant and irrelevant, and rather substituted with florid descriptions that can't be quantified. What you like is grea
 t for you, it's just not science.

This was the last time I checked- it might be that there are newer, more cost-effective DAC's out there, but at that point I think you've got to get realistic- what is your listening space? Ambient noise? Your speakers? Are you sitting down to listing in the best position?

While publications funded mostly by advertisements from makers of expensive cables, power conditioners and outboard DACs don't want you to know this, the iPhone 5 is a better audio source than most DACs will be when connected to a computer or CD transport. The only difference is that the iPhone has a level 6 dB lower than a proper CD player, but the iPhone still has more output at 1 V full-scale than some outboard audiophile DACs!_

If you secretly put an iPhone 6 inside of a case with a 1/4" thick milled front panel sporting a pretentious sounding name in cursive script and a $1700 price tag, many of the same "reviewers" who panned the iPhone 6 would be telling you how wonderful this "new" audiophile DAC sounds. That's because they are like so many of the "wine connoisseurs" with "refined palates" who praise $7 wines from grocery stores when they do blind tastings but call those same wines undrinkable dreck when they watch them poured from the labeled bottles before tasting them.
