To my ears the 780's sound totally different than the Mission m51's, they're much more musical and don't have that m51 harshness. I was asking all around for the Rega's you've bought pbirkett, but I can't seem to find them. If anyone knows wherre to look for these babies in Hong kong let me know!
The NHT's are seemingly non-existant in HK as well. Though I think its more that I don't know where to find them than they really don't exist.
DIY's very tempting, where $500 DIY speakers can beat $5,000 - $10,000 ones because they don't need the enormous costs that large companies with stores, advertisements and employees have to bear. You just pay for the drivers, the wood and the carpentry, and you're done.
