If you had to build/mod a complete system of source,amp and speakers, what would you pick and how would you do it on a £100 total budget? If it's a vinyl front-end I think the cost of the cartridge should be excluded.
I will start with speakers and work back for my theoretical system. I'd build Frugal Horn speakers with these Mark Audio drivers:

I have the CHR's which cost me about £50 a couple of years ago
For an amp I'd use a TP3116 or TP3118 off ebay with a 24V PSU, or I'd get a non-working integrated locally, re-use the case/transformer/heatsink and add these:
I would aim to find an amp with 35-40V DC rails if possible

Pre-amplifier would be:

Using an RCRC network to drop voltage down for the 7812/7912 regs if the main rails were over 35V.
Sources, one of the following:
CD - Find a local CD player for sale that works, TDA1541/A if possible and add a new clock, like this:
http://rover.ebay.com/rover/1/711-5...0001&campid=5338728743&icep_item=291547954929
Add some os-cons and LM317 TPR regs for the main IC's
Hi-res - Raspberry PI running say VolumIO with a PCM5102 DAC like this:

Vinyl - Buy a Rega Planar 2, Goldring GR1/2 with no arm and re-use the motor/bearing/platters and put it in a 3 or 4 layer plywood plinth (I bought one for £15 I think it was). Tonearm will be similar to one of Nanook's on DIYAudio - a carbon fibre arrow shaft for an arm wand, a Parker pen refill point in the end of a pointed fuse as a unipivot bearing. Insert a threaded rod in one end of the arrow shaft and use nuts and washers for a counterweight. The head-shell is made from a scrap piece of hardwood.
Phono stage would be a Salas simplistic 2SK170 phono made on veroboard.
Cables will be remnants/leftovers or Van Damme if they need to be bought.
