Well, yah yuck. But I gotta tell ya, portability was the thing for me. I was spinning during the vinyl to CD transition, and I traded off carrying 3 to 4 cubic feet of plastic 12 inch disks for one 24 inch by 14 inch by 6 inch box of jewel cases. I could carry more titles for requests, but I was amazed at how heavy that many CD's were. It was heavier than my 18 inch subs. I then burned all my music to the little 21 minute 3 inch cd's with vinyl sleeves...that way I could take everything.

Now, one memory stick carries everything.

Might have to do that. Most of my big singles are 33 (1700 pieces), with the occasional 12 inch 45. I hate the 45's, it's easier to spot mix the 33's.
Most of my 12's are 1978 to 81.

I guess it's slack engineering. Possibly the designer give more importance to the 5.1 outputs than to the stereo outputs.
Anyhow, in many cases a well designed discrete I/V and/or analog output circuits will sound better than the best IC out there.

For sheer silliness, how about the integrated amplifiers that gold-plate only the CD inputs?

There is no accounting for mid fi decisions.

It's the accountants who make a hi-fi BOM into a mid-fi BOM.

As I think it was John who said so in another thread or perhaps here, the difference between a good designer and a great one is knowing where you can cut a corner or use a different device and still attain the design goals. In a cheap consumer product it is going to be a little bit of cutting everywhere, a thinner board, cheaper capacitors with lower voltage ratings, wider tolerances and every other aspect of the design will be compromised to an extent. In a mid fi product a great designer can achieve most of what they want and still not use the most exotic components to get there, he knows how to get the most out of each part and what to do to get there. Good design or great designer, take your choice.

Actually, I think it is a different comparison. Mid fi, is getting the most 'specs' and features with circuitry that you can barely get away with. Hi fi is doing the best design possible, that shows itself with improved sound quality.
It DOES take a good engineer to make cheap yet passible audio or video equipment, but it is not hi fi, or hi end video.
Think about autos. Can the best automotive engineers use just cheap stuff and get superior results, through superior engineering?

I have been working recently on a design made by those special engineers who make something that works well for an 'affordable' price. And you know, they are really sharp and even 'overeducated'. Yesterday, I had lunch with a young woman, who is in charge of the project I am working on, and she has a PhD in engineering! Wow! The circuits I am working on, are pretty good, but not 'hi end'. Still, the results are pretty darn good.

OTOH, if you take a no-compromise design (I know, an oxymoron) and manufacture 100k units, it becomes dirt cheap AND very good. Numbers save you or kill you, depending

Jan and John,
Points well taken. So to restate what I am saying then only talking about hifi. A great designer can do more with the same components, how about that. Given the same components a great designer can design a superior circuit implementation than someone who just knows how to use the components but not optimize every aspect of the design. Jan you are so right that with volume sales you can use more expensive components due to quantity price breaks and a low volume product would require a higher sales price. The only problem in this industry is that brands that become known for quality and sell in quantity often end up being bought out and end up being only a trade name in the end.
