Modern Linestages


This is a general question about how complex and expensive some linestages have become. I'm looking to understand why? I can grasp that really good volume controls are complicated and that equally good switches are not inexpensive. I also have a general understanding of the importance of a high quality power supply, which again is not going to come cheap. I just don't comprehend how you get to a 50lbs. plus preamps that cost well over $20k. Is this level of complexity really needed or is it the equivalent of the spate of 500hp "sedans" for every day driving?

After purchasing Dr. Peppard's Mapletree 2A/SE Linestage I asked him this question. He said he did not know why they were so complicated. After all, his is simple and inexpensive, and IMO is a classic giant killer (granted, no balanced or digital inputs, but I don't care 'cause the sound is superb!). Seems to me they need not be.
If simplicity also meant inexpensive it would be nice. All to often something that is very simply made, almost elegant, is a work of extreme craftsmanship. A simple circuit will do but when you extend that to better/purer resistors, capacitors, etc. etc. and so forth, simplicity adds up to a lot of costs real quick.
A Swiss watch is a thing of beauty, not a lot of moving parts but try getting one for the cost of a Timex.
Sometimes paying more gets you more and sometimes it is a case of a fool and his money are soon parted.
Let's look at the cost of some of the key components in a top quality preamp - like my tube preamp.

- 45 step Shallco volume control $300 - $450
- Duelund/Vcap or like quality coupling caps can cost as much as $200-$500 each depending on size. Mine takes two of them! Two Duelund 3.3 uf caps cost $400!
- Large power supply caps (computer grade). You know the ones that look like coke cans or even bigger. They cost up to $30-$60 each and my preamp has 12 of them!
- Large transformers are also very expensive. They can cost $150 - $300.
- Mine came with 7 tubes. 4 of them are NOS RCA 6sn7's from the 40's and 50's. Tubes alone can cost $300 or more for all 7.
- In addition, my preamp has chokes, expensive solid core copper wire, ceramic tube sockets and other parts....
- What about the cost of a good, well made chassis with all needed hardware, knobs, footers and the particular finish. I bet such a chassis made from heavy stock, with a thick face, special finishing, nice knobs etc... can cost up to $1000. I am not sure, but speculate here.

I see a lot more than a $1000 in parts here folks.I see closer to $2800 in "parts" before all the labor needed to hardwire (point to point) this puppy.

I suppose some preamps have a higher mark-up then others, but once all the costs are considered, the mark-up on some is not even 100%. Costs also involve, R&D, labor, insurance, building, utilities and on ......

So how much should a preamp like the one above sell for? I mean sell for direct from the builder with no additional mark-up? How much? $5000 - $10,000?
Uru975,
Well stated post! In my experiences simple circuits with fewer parts count(but of premium quality) with a high standard built do usally sound better than than complex (multiple stages) designs with many parts crammed into a chassis.

My linestage is very simple in actual circuir(no signal path capacitor or resistors) layout but admittedly heavy(73 pounds) due to the weight of various transformers,chokes and the two separate steel chassis.
