Yeah, I would have to say go for the $500 offer from Magnapan. Damn hard to beat that one, even going DIY.
Keep the budget low on the digital front end and get a Toshiba 3960 or 4960 universal, even better and mod it. That would run you about $200 tops.
Then take the savings from your front end and buy a used Pathos Classic One integrated (does that have enough juice at 70 tube watts for the Maggie's). I've seen them on Audiogon for less than $1000 in the past.
Oh yeah, then go make your own cables from one of the many, many recipe's available.
Yes, I'm advocating a lot of DIY and used stuff, but that's the only way to get good performance and value these days.
Enjoy,
Bob
