The droop isn't something I've noticed subjectively, but clearly its a real effect. Its substantially less than 'NOS droop' for example which many people don't notice, or perhaps even prefer.
Incidentally I've been winding small trafos (shown on my blog) this past week and took some in to my school (where I'm a teacher) and encouraged my colleagues to have a listen, putting them between smartphones/laptops and their headphones. They all loved the SQ improvement.

I was struggling with how to regulate -ve rail but worked it out about the same time your message came in - once i had worked out what search terms to use it was easy. Thanks for all your help. I might be ready later this afternoon to put a parts list together for shopping this week. I've decided I'll have a go at making a small pcb to mount it all on. I will also look into these LM317/337 as i will have to buy multiples more than I need for this project the adjustable variety might be more use in the long term if I have spares.
Your help on cap values much appreciated.
From in an earlier post you cautioned "Plus, when picking up a supply inside the amp you always have to watch out for grounding issues. Power supply ground + shielded cable = potential ground loop." Can you tell me what I should look out for with regards this? Wasn't palnning on using any shielded cables - or do I use a coaxial from the preout?
Will report on how it comes together - hope I don't blow anything up
LM317/337
After looking at these LM317/337 I am going back to LM78xx/79xx on account of how much hotter the adjustable regulators seem to get. Am I correct in my reading that non-adjustable types disipate less heat? The heat sink size required on that LM317/337 is bigger than what space I want to occupy.

Have you tried other sites for can heads 🙂 head-fi.org for one.

Doh! I knew as I was writing that something wasn't adding up. THose extra volts have to go somewhere, regardless of what they are passing through. Basic physics.
