- What do you mean when you say that the state of the art is that a
- hobbyist can't build equipment better than he can buy? I certainly
- cannot believe this.
-
- The first excellent example is the case of passive preamps (and
- buffered passive preamps). For a small investment you can build a
- unit as good as anything on the market, and the effort is small. Corey
- Greenburg's article in Stereophile is easy proof if that. If you want
- a good phono preamp, take a look at Jung's Audio Op-Amp Cookbook; I have
- built a couple of designs straight out of there that were astonishingly
- good, and received nothing but amazed compliments.
-
- It's harder to build amps than it used to be, just because the designs
- have become so much more complex in the transistor arena. Tube amps are
- as easy to build as ever, and sound just as good, but finding parts is
- becoming a problem, I admit. You can easily build a tube amp that will
- sound as good as anything out there, but it might be a lot cheaper just
- to buy one of the shelf.
-
- Admittedly, that's the case with CD players too; building your own is
- a close to impossible task. Still, though, you can build your own analogue
- section and your own D/A facility into an off-the-shelf player. It's a lot
- more work than making a tonearm, but it's no more work than making a really
- good tonearm. Look at Jung's modifications for the Phillips players just
- for a start. For a fairly small investment you can bring a cheap player
- pretty close to the state of the art.
-
- Speakers? Sure, you can build state of the art speakers. The parts are
- available, it's just that the designs are much more complex. Speaker design
- is as complex as it ever was, maybe even more so. But that's not to say
- that you can't steal someone else's design and build your own clone.
-
- The state of the art is a lot more complex than it used to be. However,
- the modules that the homebrewer has to work with are a lot more complete
- (and more complex themselves) than they used to be. Plus, some of the older
- designs can sound amazingly good; in some sense the real state of the art
- hasn't changed much.
