content: The fact that it's called "High-Rez" was enough to turn me off. It's like they want to allude to "High Resolution" capabilities of their product but really it's no different to your bog-standard stuff already on the market. A quick CTRL+F finds only one reference to anything High Resolution concerning their product -"Ultra-wide bandwidth for high-resolution listening"- whatever the hell that means (or are they referring to their "unique backer's" own ears?).The whole thing is a very clever play on words. It's like labelling a food OrganikTM-- It has zero meaning.The other thing I noticed was "Designed and Assembled in the USA". All well and good, but probably sourcing all parts from China?

content: You know, what really strikes me is that this enthusiastic guy in the video just has to know what he is talking about. I would believe him that he actually did the design of the board, but geee ...You can't be an engineer and and a mystic at the same time!Hence if he really is the electronics designer in the project he sooo f***ing knows that he is talking complete bullshit. So WHY?But hey, apart from the nonsense, the video is much more fun to watch than the batterizer guy with his (un)compensated probes and test-signals and his unused soldering iron ...

content: Quote from: free_electron on August 21, 2015, 03:03:41 amUh oh. I smell a new product here. Through painstaking research we have found that flux cored solder really does not provide a favorable sonic environment and translative medium for the electrons so we have developed coreless solder. (FIll in little animation here "Explaining" how it works) the solder and flux are devided up into particles so fine that they are indistinguishable from one another and governed by the laws of Brownian motion and thermodynamics creating a structure when flowed that permits sonic clarity and wellbeingness that must be heard to believe. We need an investment of $300,000,000 to bring this to market, and buy Lamborghinis for every day of the year.

content: Honestly, why don't they just tell people to upgrade their computer's sound card for one with a breakout box and good quality DACs for much less money? Then they will get many more features like the ability to record high quality audio via XLR, line, high-z line in for guitar, etc.It's the most useless audio gear anyone could think of designing, since many other things out there can do exactly the same job with similar/same/better results at a cheaper price for what you get!EDIT: Forgot to mention that high quality output of audio is NOTHING without high quality headphones, amplifier and speakers. These are the absoluteB I G G E S Tlimitation (probably by a couple of orders of magnitude) in any system nowadays, not the DAC's quality!EDIT 2: $3,000,000. Wow... I might just have to build some cheap audio crap that nobody needs and sell it for a high price.

content: I had a guy tell me in a phone call that too many solder joints will effect sound quality! I kept my mouth shut and played along cause he was selling some stuff I wanted but was on the fence about the price. He also was a proponent of using only silver wire with silver solder and slipping teflon sleeving over it cause traditional insulated wire was "Not made right"

content: Quote from: AF6LJ on August 30, 2015, 09:18:54 pmPersonally I don't have any problems with that. I kind of like gear that has been ridiculously over engineered. I mean why not! It's just another type of luxury. Some people like to pay for design, others pay for 100g of silver in their pre-amp.Like building your garden fence using calipers. Completely useless but you know that the fence elements are mounted within a tenth of a mm. However, it would not keep more burglars away.Or like a kitchen knife made from exotic steel or a cutting board made from special wood. However, the hobby-chefs typically don't insist on the idea that the cutting board makes a difference in taste though ...

content: I would love to play around measuring that using high end equipment. It seems kind of stupid to hook up a "nice" amplifier to a speaker though, i mean you can have a great time listening to some guy bang on a garbage can in the subway if you had a few drinks.. unless maybe you connect the speaker to some kind of laser displacement measurement device or such to try to categorize it betterif you think about it as a precision device for controlling displacement via EM field then it becomes interesting.I would find an analysis of the gain drift and distortion etc very interesting.. i dont care much for the music enjoyment part of it though+ Why don't they shield stuff with mu-metal or w/e if they are going through all that trouble? I'm sure all sorts of hard to measure things happen when HF is conducted into a speaker btw, stuff like the magnetic material heating up in diff depths and causing a diff responce to a field, center of mass change, etc etc.. but its probobly hard to measure PPB shit. I don't think its stupid to investigate the physics and keep pushing decimal points, so long you keep in mind the "euphoria drift" of the mind.. most people are just not interesting in detecting things that are probobly not going to be useful for hundreds of years or will just be published in a esoteric physics journal/book...if I had the money I would probobly make mu-metal cans for DC circuits that light up light bulbs lolidk why people cant just appreciate some stuff because it does something better in some way then every thing else (if you believe something is truely better without any kind of trade off you are an idiot (unless your cracking jokes about your ex)) and study it as a curiosity?the only truth is that sales guys will be sales guys lol-what it is ) curious novelty circuit-what sales guys pitch it as ) time travel-what the chinese ebay version does ) ends up being used as a compact radio jammer in nuclear weapons decoys
