    Excellent PIC primer, dude - having got the hang of Arduinos and AVR stuff, really wanted to have a go with PICs but it all seemed waaay too advanced until I came across these pages. Many thanks :)

    Started working in my head on a preamp using the PGA 2310, so this site is going to be looked up pretty often! Lots of interesting ideas here. I too chased the 5-gang mech. pot with servo control dream. The major problem with pots is the noise that gets out of hand with time.

    This is for a 5-ch version of the Leach amp. I built some time back.

    I do some woodworking too!

    This is the first time I am coming across such a complex preamp. It has completely blown my mind. I may not be making this design, but it has certainly inspired me to carry on with my DIY audio work. I have been stagnant for a number of years, as components are easy to come by over here.
    keep up the good work.

    thanks for itching the scratch that so many of us have as found listeners of our Rogers speakers. Your conclusion of the sound quality of the LS5/9 was spot on. Love my LS2, LS6 & LS5/9's. Don't have enough rooms in the house for any more.

    Mark - just to say thank you for the extremely well written and genuinely helpful and interesting PIC getting started guide.

    Looks like the pages haven't been updated for some time, so I won't hold up much hope of the 'applications' section being completed any time soon!

    But as an introduction to PIC programming, I found your guide invaluable. Thank you.

    Great website, Mark! I programmed PICs in college for an Embedded Design class, and thought I'd get back into it recently. Your beginners assembly tutorial was a great refresher. Thank you!
