When I first got into this HiFi lark, mainstream products were generally dreadful, and an enthusiastic amateur with a soldering iron and a bit of basic knowledge could build an amp on his kitchen table that would outperform most of the commercially available equipment.
Magazines like practical wireless, wireless world, everyday electronics had a never ending stream of tweeks and designs that the enthusiast could build - and make a real difference to the quality of his setup.
Those days have gone. Mainstream products are now pretty good, and all the bits that matter are tucked away and beyond the reach of the enthusiast. Nanometer geometries in D2A converters, fancy digital filters and sampling techniques embedded in firmware - it might as well be magic for all the difference an owner can make.
So the keen enthusiast is reduced to dicussions about mains blocks and the difference between two perfectly good and identically sounding bits of speaker wire.
Its no wonder that forums of this nature are dying. To a certain extent they have performed their function, mainstream HiFi is now pretty good - we should pat ourselves on the back.
Hi,
There is still the enthusiasm, but I agree the lack of interest in technical/science subjects has led to a decline in an interest in Electronics. This can be seen as a decline in publications, where many electronic publications are not available in newsagents etc.
Diyaudio.com has many interesting threads, but they are technical, and less hifi music or system based discussions.
Unless you subscribe to audio or speaker building publications, then the current publications (hifi and electronic) now seem very defficient in audio projects, although, there have been class D designs recently (4 years ago). In fact for hifi, I have not seen any diy projects for decades, apart from hifi-critics speaker design.
Despite the integration and increase in complexity of DAC chips, you can still build your own DAC using these chips, since the Internet allows for ease of data sheet retrieval, and manufacturers forums to ask specific questions, which were the domain of bona fide audio manufacturers only, previously.
You can still build amplifiers, class A, AB, D, etc., or purchase modules, it is just that hifi magazines have perhaps, lost their way. You can implement your own digital filters using COTS DAC's, if you want. In fact, DSP has offered another expanse into which you can modify.
Aspects such as Wifi, bluetooth etc., are possible to implement yourself, but, you need to be an electronic, software and networking engineer to build your own project.
It seems that the expanse of possibilities has created a rabbit in the headlights effect, or people just don't have the range of capabilites required. Perhaps projects need to be a two person affair, but finding two people who live close to one another interested in the same subjects seems rather rare.
So, the enthusiasm and interest exists, but the number of people interested is woefully limited.
Regards,
Shadders.
