What's inside these aluminum/metal cases?


I have three links below to pictures of amps with their lids removed, one is an integrated, and I am curious to the thoughts of those that have the technical knowledge of amps to discuss the inner componants and order of design.

We tweak our systems with expensive cables, yet I look at pictures such these pictures and wonder what all the signal must go through.

Let me put the disclaimer out, I do not own any of these amps nor did I single them out, I just happen have pictures of them with their "hoods" off, if I had some others, I may of included them as well.

I call this incomplete engineering. Nice front panel and jacks but a rats nest inside. Layout is an art. All audio designers should take a course in RF, where if the layout is compromised it won't work. Proper layout means everything being in the best possible place for the least ill effects caused by its location relative to everything else. Some of the best I've seen are Accuphase, Krell and Luxman (check their web site-wow). Too bad the present Lux stuff isn't available here. Their engineers actually still use shielding and lots of it. The old stuff is quiet, I can't wait for the new.
Bishopwill, I have to know the name of this 10K + tube amp you described. Was it made in Italy, by any chance (just a guess)? Ascribe it to a different mentality or interest focus, but most every German audio magazine publishes at least one photo of the component with its "lid removed" in each review. Some photos even are accompanied by arrows to special features that make the component more attractive! What is funny is when the arrows go around the areas where there is poor assembly work! With the hood removed and the electonic parts catalogue in hand you can easily calculate the cost of the parts. It is usually about 10 to 15% of the retail price.
Both brystons look OK. I agree that there's a bit too much "loose wire" floating around for my liking, and much more than my densen integrated (which is a $1000 amp). The ML383 is neat, but it looks like you're paying for lots of stuff which may have little direct impact on the audio quality. I wondered why ML stuff cost so much.
As for components costing 10-15% of the amp ... I think that's a little low, but it does reflect the food chain of components->manufacturing->marketing->distributor markup->hifi shop margins. Such is the way with all electronics, with the general rule that the higher end you go the more you are gouged. Also the price of things reflects what people will pay for them, not how much they cost to make.

The bottom line is "how do they sound"? (I'm a fan of minimalism since minimalist designs (passive preamps, selector switches located near to the RCA inputs etc) usually sound better to me for the same $$). I've never heard any bryston or ML gear, but from what I've seen above the bryston looks to be better value for money.
Seandtaylor, it is an interesting issue you bring up, at least one I have been thinking on lately. Now, how to put it to words!

There is part of me that says it's just about the music, I want to hear the music the best I can.

Then there is the part of me that remembers the pure joy of using the features that the 383 includes, and I really enjoy the performace to boot. I don't doubt that those features cost, but like I say, I enjoyed them.

Now, to those like you that may care less, no need to pay for them, as in todays market, there are plenty of choices, although I sometimes think this is not such a blessing!

Funny thing about your "minimalist" desire, I have an article that talks how Mark Levinson was the originator of that. (Two notes on that, first I will point the obvious, back them it was ML the person. Second, as far as the signal path, I don't think they have deviated from that.)
