No it's not. Your statement cannot be "objectively true" because it's not objective. It violates every rule of economics. In order to judge the "worth" or "value" of a product, you must know who is buying it and what their preferences and definition of "value" are. To someone who views low price more than good sound, many headphone amps would be a "lousy value." To some people, any CD player over $100 would be a bad value. But for someone who views sound as the most important thing, and values sound to a *much* greater extent than low price, a $10,000 headphone amplifier could be a phenomenal value.
What tweaked everyone about your statement is that it is presumptuous -- you presumed to know everyone else's values and somehow make a determination of "value" for everyone else, even though your determination was based solely on your own personal preferences.

| Compare the material value of any headphone amp with a typical integrated. |
Many of us have, and a headphone amp is an incredible improvement to us.

| And what else can you do with a headphone amp but listen to headphones? |
Not a very good argument. What else can I do with a $200 blender but blend? There are lots of things that people buy that do a very specific thing, but do it very well. Some of those tasks can even be performed by other devices. Unfortunately, not as well. So specific devices are often a good value for people because of their better performance.

| Hey, with an integrated I can listen to headphones AND speakers. Plus I have umpteen inputs, selectors, tone controls....wow! |
By that logic, the latest Sony or JVC mini-system with bells and whistles and knobs and flashing lights and buttons should be the greatest value of all...

| Get my meaning? If my Marantz sounds great to me, why in God's name would I ever contemplate a headphone amp, even one as good as I'm sure you make? |
You shouldn't. Some people can't hear a difference; for others, the difference isn't big enough to warrant the expense. If a headphone amp doesn't sound any different to you than the output of your CD player, or not better enough to spend the extra money, you shouldn't buy one. That's why most people on this board encourage people to buy from a dealer that has a return policy.
However, most of the people here *can* hear the difference, and they post their views accordingly. For example, Sennheiser HD600s *cannot* be driven to their potential by a sound card. That's a fact. However, some people insist that they sound the same when driven from a soundcard as when driven from a quality headphone amp. Those people do exist, and their impressions are entirely valid for them. Perhaps at the end of every headphone or amp recommendation, we should start including a disclaimer "Warning: it is possible that you may not hear a difference between Product A and other products."

You are. People just take exception when you present your opinion as an objective fact, when it is far from being an objective fact.

| How many "veterans" here have actually tested the headphone outputs of mass market integrateds? |
I can't speak for others, but I've tried them on many and a headphone amp has always provided better sound to my ears.
