I'm not Richard, of course, but what's wrong with trying something different that works equally well, or even better? I've been loving diamond buffers since the first time I saw the LH0002 schematics, but Richard's buffer is as elegant and simple as the DB, and its figures are quite amazing.

Because this isn't about "flavor of the week". It's about what works. To me, this is engineering, not fashion.

I was thinking that the circuit being discussed as in post 1 could do this, so there is even more parts involved. This unless you see the last CFP pairs as a buffer which I dont in my point of view. Too complicated then for what it can do, like I mentioned before JLHs design can do same or better and is less complex.
Its not difficult to do minor changes to give the circuit in post 6 voltage gain, have the kind of performance described and (there is more than one way), its basic stuff and already done ages ago.

I have nothing against Linear Audio btw but I can see some reason behind the commercial argument made here. This has come up a few times in the forum but resolution is not easy on this topic.

Guys, we're talking about an open-loop small-power buffer capable of 0.001% THD into 30 ohm - it seems there's quite a lot of good engineering behind these figures...

Interesting attitude.

Thank you!

I got the idea for Linear Audio in 2009 at the European Triode Festival, when discussing audio pubs in general and lamenting their disappearance. Since I always seem to be the sucker at such occasions (and/or the guy who drinks too much), I took euro 20k from my retirement fund and started Linear Audio.
By now, it seems to be able to pay for itself. Whether I ever get back my euro 20k - who knows?

You may have noted that I take one article from each issue and put it online for free, as soon as a new issue is published. But LA is a printed issue because I personally like printed books, I like to have them at my side, open where I am, and leaf up and down the pages to check things, enjoy the smell of ink. Unfortunately, that doesn't come for free. And it would be very disrespectfull of me to people who pay for LA if all the contents would be available elsewhere for free.
It is something the whole publishing world is grappling with. It's a risk I take - if all content is stolen, and nobody buys anymore, I'm [starts with an f and ends with ucked].
BTW Linear Audio does have it's own thread here but that's more admin in nature - obviously I can't have a thread that shows all LA content.

What I find interesting is that people are willing to shell out $ 100 for a boutique cap on a simple "I did, and it's great, sound stage has never been as good"- type post, but have issues with getting a printed book for $ 28 that REALLY can advance them in understanding what it is they are doing. Very few appreciate the knowledge and insight people like Scott Wurcer and Dick Marsh put in their articles, and they will never appreciate and understand it from a scanned circuit diagram. One of the few riddles in life I still have to solve

or possibly at the post-event, where indeed too much drinking was going on.
