While most of said equipment is far beyond the means of the average consumer, the ability to duplicate it or even improve upon it is possible within the average budget by "doing it yourself". See Cary Audio
Designs, Sophia Electric, or Manley Labs for instance in regard to "state of the art" or "high end".

239:). The DIY community started building replicas (or improvements, or modificiations, depending on how you look at it) of the Gaincard using various chip amps from National Semiconductor and other manufacturers in an attempt to see if good sound could be obtained. The simple circuit was easy to make and some even started offering printed circuit boards and kits to make construction even easier.

437:"DIY audio involves "projects" directed to audio. Many DIY audio people fancy themselves to be audiophiles. These people use rare and expensive parts and components in their projects. Examples are the use of silver wire, expensive capacitors, non-standard solders of various alloys, and use of parts that have been cryogenically cooled."
235:) These construction techniques went against the current thinking at the time, which favored large power supplies and discrete amplification. Estimates are that this amp cost less than $ 100 in parts, but it sold for $ 3300 with its small power supply. Controversy ensued, with a number of positive reviews (see

Ok, some DIY audio fans are audiophiles. Why else would they be building audio gear. But saying "these" people use "rare and expensive" parts is dumb. The examples are not rare, for example silver wire. And most kits I have seen built by DIY audio fans use common components. Look at gainclone

Gainclone or "chip amp" is probably the most commonly built and well known amplifier project, it is extremely simple to build and involves only a few parts which all are readily accessible, and is very inexpensive. As an amplifier it is highly regarded by many in the DIY community. The term
