Are you mounting both FETs on the same heatsink? If so, how about drilling and tapping a hole between the two FETS and using a short piece of metal bar and a bolt to clamp the FETS to the heatsink (with thermafilm or whatever in between the FETs and the 'sink). As long as the metal bar only...

^^^ Looking good, Gurusan. FWIW, I drilled a quite a few vent holes in my DAC's case (top and back, close to the VRegs). As you say, the regs' heatsinks get pretty toasty. I got some larger value MCaps (1.5uF) and am going to install those tonight to get the -3dB point below 10Hz when the...

Finally got round to finishing it. I put the transformer in a separate box. On my desk beneath my desktop Starving Student Sounds pretty good. I swapped the op-amp for a LM4562NA and it sounds nice and detailed.

Thanks everyone. Seeing the thread on The Art of Sound certainly clears things up - especially this post which covers just about everything discussed here so far. I've already bypassed C27, C28, C30, C31, C6 & C54. I don't really feel like tackling the resistor and capacitor changes required...
