So you are saying $1060 for everything or just the cables?
I mean I might be wrong but its like $100 per board plus about $100 for the psu and another $100 for the enclosure and you can mill it yourself so about $400. I guess if you include the jacks and cables and everything else it would come to about $500. ya your right never mind.
That's also a very basic 2 channel based off the prices from GJA. Don't forget you'd need a pot which is not very expensive but adds up to the cost overall. Not to mention if you're going DIY the whole point is not skimp out on quality just because you have a small budget to begin with (but also saving money compared to retail), most would also opt for a better transformer.
