    Ha! You've found Mike's site too. He's a great bloke - you'll see him around the headphone forums as PinkFloyd.

    I'm currently building the Hart (Chiarra) Headphone amp - one for me, and one for a friend. The friend has gone for one of Mike's crossfeed circuits, so that will be levered into place as well. For my headamp, I'll be doing my own PSU, rather than using the Hart one (being a cheapskate, apart from anything else).

    I'd be tempted to go for an encapsulated toroidal - RS do the Nuovem ones that are well thought of, and Farnell do some which are an absolute spitting image of the Nuovems. ....Ah - just seen the bottom of Mike's PSU build page where he recommends the Nuovems...

    Man these things are like hen's teeth.
    I 've found this site in tiawan which is well thought of and has a good selection including the silmics! : don't know what duty and VAT will do to these though...

    http://www.thlaudio.com

    how about the panasonic FCs?

    The FCs are meant to be good, but I'm not sure if they're in the same league as the Elnas. At least you can get them, though (Farnell stock them).

    yep I've looked at Angelas and they don't have the values I need.
    The Tiawan site seems to have the full range and I'm tempted by the silmics...if they fit in the Xcan.

    Just finished the Hart, which isn't quite standard.
    Basically, I've changed the power supply to be +-12v rather than 15, to allow me to use the AD8620 chip (which is on a Brown Dog adapter to fit it into the DIP socket). Also replaced the regulator bypass caps with Elnas. Omitted the balance control, too. Added Mike's crossfeed board (as mentioned above), and fitted a relay driven switch to allow switching of the crossfeed on and off.

    It looks very nice in one box. Shame I can't afford one at the moment, as I'm just about to invest in a Rega P3 deck.

    Nice one Retro on the P3 - I'm an LP12 user (with DIY Armageddon - yum).
    The one I'm building for myself will use a homebrew PSU, which (in theory) should be at least as good as the standard Andante - fingers crossed....

    Sounds great - needs burning in yet....

    I'm flattered - as I am an apps enginer for Analog Devices.
    Had a look at the Brown Dog site also.
    I suppose I should not be surprised - had a tech query last month that uncovered a group of people swapping out JRC op-amps for AD ones in Marantz gear.
    I believe they have their own forum somewhere.

    Watch out for a new (unannounced as yet) device to be press-released etc. in 8/10 weeks (AD8099).

    Well swapped the original philips valves out of the Xcan V2 with some mullard ones. I was originally going to use sovteks but Sean at IES came through with the mullards...excellent!

    Easy to swap em over 2 min job.

    Results...very impressive. The sound is warmer and smoother yet at the same time its way more detailed and transparent. ( I can now hear what I think is a metronome ticking away in a couple of tracks!)

    Its not quite like having a new amp but its darn close.

    Now to find some caps!

    And I must swap that nasty red led for a blue one!
