I upgraded the power supply and changed the BC109 and caps + resistors for low noise ones the parts I used were from RS (I have 250 BC550 min order for £8.50 ) this cost a lot less than the DADA kit (I have 3 quad 33 in various rooms along with both my sons who have 33/405 combos ) Also a mate who has 33/303 combo. With the 16v power supply giving more headroom they sound great
