I was visiting my friend who is a professional violinist and couldn't help but notice that his music system was probably the worst sounding I've ever heard, basically plastic salvage crap from 80's. I decided to try and build a musically satisfying system that a poor musician could afford...
The point of this exercise was to see what would be the cost of a relatively high quality sound system using the least expensive DIY components.
FOR SALE:
1. The source - Sony PS-1 SCPH-5501 Modified CD Player with integrated remote. (SOLD)
2. Preamp - 128-Step Relay Controlled Attenuator with remote control kit in mid-sized aluminum enclosure (all eBay) - $195
3. Amplifier - TPA3116D2 in lg-size aluminum enclosure (eBay) - $100
All cables are DIY.
Programmable remote controls PS-1 CD functions and volume on the preamp.
The amplifier is equipped with delayed trigger input which allows on/off operation via preamplifier.
Unfortunately I could not make my own speakers so this component is not included in my project price calculations.
The results were quite excellent. For a comparably low cost (very low cost) I was able to put together a system that would rival systems many many times its price in terms of sound quality.
The total parts cost for the entire system was calculated to be under $200.00, the most expensive part being the remote controlled preamp. It took me approximately 5 days to cobble this entire system together once all the parts were in place, and now I have a great present for my friend!
EDIT: Friend politely refused. Now it is for sale - $390 takes it.
