Hello-
Way back in the day I was as oblivious as the next guy, more bass is better and the cooler looking headphones are the better they must be
. But then I discovered Head-fi (and my poor unfortunate wallet). I learned about good headphones and stepped up to entry-level audiofidelity and re-encoded my music library (at the time it was 96-128kbps wma ouch!) into high quality format (EAC ripped Lame encoded "alt preset standard" VBR) and got some good headphones (KSC-35 and Ety ER-4P). I had read a little about amps and that they were the next level of headphone listening but never really experienced "amped" audio or read too much about it.
Now I'm curious. I have some basic questions about headphone amps. First of all- what do they do exactly? I am confused on the concept of an amp- because it seems to me like adding additional devices in the audio chain from the source to your ears can only degrade the audio, since it can't ever really improve the audio that it recieves from the previous source. I also read that the high echelons of headphones pretty much require an amp to be used to their potential- and if you buy an expensive set of headphones and use them without an amp you are basically neglecting 75% of their performance capability.
For example- if I go straight from my 2G iPod (my only real "source" BTW- like I said I'm at entry-level audiophile still) into a pair of headphones, versus iPod>amp>cans- does that not introduce an extra device which can degrade signal quality, or extra connections to reduce signal quality, etc?
I know enough (or do I...) to know that amps are not really used for their volume-enhancing properties... but how does that all work? I guess ideally you are using line-level sources (which actually are extremely loud, if you plugged headphones straight into a line-out port right?) and the amp actually attenuates the volume and makes it adjustable via variable levels of gain.
Would not the "ideal" amp be merely a volume attenuator from the line-level source? (I guess that's why you can buy a $1000 pot!?) Why would you introduce extra elements into the audio path if you can take the unadulterated line-level audio coming straight from the source and reduce it to a listenable level?
Unless it is the "flavor" or "interpretation" of the music that the amp imparts onto the audio which people are after? A rough analogy of what I'm trying to say might be having different orchestras play the same piece of music. Each will play it slightly different, and some people might prefer this orchestra or that- based on the type of music they listen to. Obviously listening to a particular song played by the London Philharmonic vs. Podunk's High School Orchestra will provide pretty clear indications of "better" and "worse", but there are also many "lateral" comparisons where better and worse aren't as appropriate as "different". So the London Philharmonic might be the $5000 amp + $3000 headphones and the high school orchestra be the el cheapo amp one might find in a standard consumer-grade electronic (like PCDP or iPod)?
So- I'm looking for kind of an "introduction to amps"... even links to webpages where this has been previously hashed out would be great. I'm just curious to see what it's all about. Although I do not plan on entering the "amp arena" in the near future I could forsee myself eventually buying an amp to enhance my ER-4P's (when using the 4P>4S converter cable?) or any other headphone I pick up in the future.
Anyways, thanks for reading and I would love to hear some replies to help me understand
