No, not this one. ATLANTIS it's name. It has variable amounts of voltage (3; 4,5; 6; 7,5; 9; 12) @ 800 mA.
I tried aluminium Ram cooler heatsinks directly on each of the 1543 chips (instead of the plate) but wasn't happy in the fact they seemed to be even hotter then the plate, in the end I put the plate back and stuck the ram coolers to the top surface to increase the mass & conduction area (also used a heat transfer pad so the LM317 regulator next to the chips was cooled by the plate/sink assembly, it gets HOT but there's no room for a sink of it's own.
I then drilled 24 X 5mm holes in the case above the sinks (plays hell with the screen printing but I figure when needs must
When you put the case top on now the ram cooler fins are in contact with it so the whole case acts as a sink and just gets slightly warmish and together with the cooling holes nowhere gets alarmingly hot.
and how did You put this cooler with those chips together? with some glue?
max ambient temperature of 1543 chips is about 85 degrees C and of LM317 is 125 I guess, so maybe it isn't so bad...I am still waiting for the PSU...I have some bad luck, 'cause I bought it from kinda strange seller... :/
usually with RAM heatsinks, somebody will use something like ((Arctic Silver)brand) Non-Conductive Silver Thermal Epoxy. You glue the ram heatsinks right onto the chips.
It can accept any signal to the limits of the DIR9001 input receiver. That is 24 bit 96 khz. The 24 bit will be remapped to 16 bit internally, the 96khz signal remains intact I believe. Therefore highest real resolution is 16/96. I am not too sure but I believe this is correct.
Rather simpler then that, they came with a self adhesive thermally conductive 'tape' on the back, just peel & stick
The Dacs & regulator were probably fine, but I just don't like SS components getting hot and keeping them cool has got to be better for them or at least extend their lives.
Now, even with the standard 12V switchmode supply it gets nothing more then marginally warmish, with no hotspots at all. Just makes me more comfortable
How is that working out? I'm not sure I'd put those MKT caps on top of the 'sinks' surely that would insulate them again? Love the Vishay 'Cap' feet though Whats the sound quality like?
