Rather than king I would think anyone would want to be "the most interesting man in the world".


you want to be him?

None taken Nezbleu. With that kit, you could do well to DIY the firmware to enable the volume control functionality, and replace the 5532 buffer with something more interesting.

I honestly didn't know what you were looking for, and, well, most of the dac kits out there read like a copy of the factory board. I think they fall-back to the Chinese prefabs is largely predicated on the soldering difficulty.

I honestly don't know what I am looking for either. :). I have built several pieces of audio gear, some using circuit boards from group buys on this site. I think most of the things I have built are better than much of what I can buy in the same category, at least for anywhere near the same cost. One of the few non-DIY items in my system is a Logitech Squeezebox. It does a nice job of making my digital material easily and readily available, although probably 80% of my listening is via vinyl. I think of the Squeezebox mostly as a transport. It also contains a dac and has audio outs, but it has a reputation for less than stellar D/A performance. I don't know whether that reputation is deserved, since I don't have a standalone DAC. So I have an urge to build a DAC. We are often told here that things like component quality, power supply, and especially board layout along with overall construction and wiring are the "important" factors that distinguish a good piece of gear from the usual... That's why I built a Salas DCB1 preamp, and I built one of PMA's phono preamps and powered it with a Salas shunt regulator, etc. I have a lot of fun selecting components, soldering boards, doing the casework and wiring, and making a finished working unit. It is very satisfying, and so far it all sounds good.

Has DAC design reached the point where the chip maker's reference design is as good as it gets? If so I'll shut up, buy a Chinese ebay board, box it up, and be done with it. There's not even any real point building something like a Salas Reflektor regulator if the board already has (perfectly good) series regs already populated. I realize that with SMT parts and very small chips it gets harder to DIY this stuff and expect great performance, and I'm not really interested in messing with firmware.

Finally, I am just a bit disappointed that on a DIY forum we are arguing about which expensive retail DAC we can buy, instead of which killer DAC we can build.
 
being 'medically interesting' is particularly unfortunate - they parade interns through and run you through your paces, demonstrating symptoms, when you are a once in a decade case

Yeah that happened to my wife last year. She had what turned out to be a hard-to-diagnose and fairly rare autoimmune disease, and while she was in Emerg every resident and intern came through to retake her history. Hopefully that saves another​ life.

I never disturb my neighbors with music, though I have been known to mow the lawn only once every two or three weeks. Ancient history now. One of my heros is a guy whose yard maintenance came under his homeowners association scrutiny. He photographed an endangered bird nesting in his yard and threatened them with a federal lawsuit.

That's good.... Maybe I can use that here. :) But I don't even have a lawn here. Lots of trees, plants, flowers etc. But good, funny idea.

WoW ! Thank you very much.... sorry I haven't been writing articles for a long time..... but still interested.

I am older than dirt, but still above it.

Well, it appears I've come to a major crossroads....... I'm a survivor of -- wooden spoons, lead paint, no car seat, no seat belt, no bike helmet.

May your coconuts never hang lower than your grass skirt.

I'm so old I remember when water was free and you had to pay for porn.

But old enough to pretend I can't hear.

I'm old. You're ugly. Life's not fair.

Anyway, the first to forget is the happiest.

I might not always drink milk,
but when I do, I prefer Dos Boobies.


THx-

Richard
