I'm sure we can come up with something if theres enough interest, I've never tried this chip yet so may have a go at hardwiring one up first, see how much potential it has although Alex hasn't filled me with confidence
I do have hearing damage courtesy of Telstra employment, and my hearing in right ear varies with blood pressure. Shit, I can't hear a thing with my right ear, some f'wit must have upset me with such a nasty remark ! Anyway, Rick posted a while back about people with hearing damage being able to sometimes discern things that other can't re audio deficiencies. In any case, several Grotto members are able to better comment on whether this hearing damage has affected my ability to listen to and modify gear for extremely high quality ? I am sure you are aware that one of the guys on your extended listening panel has already been able to tell for himself whether I am completely deaf or not , and whether I am able to judge audio quality ?

Soon as I can find a good priced UV box, may actually have a bash at building one My mates got a scanner thats faulty so may rip the innards out and fit a couple of small tubes in there, should make a decent little light box

I just couldn't resist having another little go at her Thought some nice gold plated phono sockets would do nicely....
Then I remembered I asked Mike to send me an extra purple LED so....
Also had a black ali knob which I didn't like on the X-Cans. Wasn't completely happy with the joints on the Rifa so re-done them. Finally thought I'd have another crack at bypassing power cap...... ;D
Powered her up and she's a lot less noisy I'd love to think it was those nasty old sockets or the corrosion on the old power LED leads or even the cap bypass but most likely damaged one of the solder joints when I re-fitted the Rifa when it was fouling the lid.
The project ideas sounds interesting - wouldn't mind having a go at a build - design goes over my head
Mike and senj Why is there a WIMA .1uF capacitor across the diode near the DC input jack ? Does the other side of this diode connect to the on/off switch ? If so, it should not be there. If this diode is in series with the input from the DC supply, it will provide reverse voltage protection, as well as giving a little extra filtering, due to acting like a small value resistor between the output filter capacitor of the PSU and the input filter capacitor of the amplifier.(In effect, a CR network) In this case , connecting a capacitor across it will let more HF rubbish from the PSU through, although the extra 50/100HZ ripple rejection won't suffer.

I'm using ATH-500s which are 62ohms I think, and I get a low level of background hiss, although its soon lost amongst the music. Over time I'll try other headphone & amp combinations (the Doudou group buy is tempting me, but I think I'll try new phones first) as I'm fairly content for the time being.
