So you can adjust bass and treble?

 

[daredevii]

The reason I ask is that when I hook my Ety's to my home amp. I get great sound with much improved bass when I can adjust it. My Airhead can't give me as much.

About a year ago I did a lot of searching, but couldn't find any. I ended up using an equalizer. I did find some rather expensive preamps that might have worked. Depending on how good the headphone circuit is, some regular stereo amps will work just fine. Hopefully someone else knows of such a headphone amp. Perhaps you could have one built for you with tone controls, or build one yourself. I'd really like to see amps with balance control too, but back then I only found one. I ended up also using the EQ for channel balancing as well.

I recently sold the Corda HA-1 as it lost out to the headphone jack on a B&K PT-3 preamp/tuner. The PT-3 is a full-featured stereo preamp from B&K with full tone controls and an obscene loudness boost that I have enjoyed with etymotic 4s, 4p, Beyer dt931, and now most frequently Grado SR-225s. It can be had used on Audiogon occasionally for about $300. Mine has been working flawlessly for 4 years now.

My only beef with the B&K PT-3 is with its lame FM tuner which lacks detail. I use a Cambridge Audio T500 instead and love it.

Maybe one day, those of us who actually have no issue with tone controls will get some respect.

Thanks for the link. I'm still pretty new to all this stuff. I know the Ety's are capable of good bass, I just haven't been able to get enough for my tastes with the iPod and an Airhead. Maybe I'm asking too much of em. Is the solution a better amp? Maybe there is no solution. My latest thought is maybe trying a super mini instead of the airhead. Anybody have any thoughts on that?

i'm wishing for just a balance trim pot; doesn't even need to be a front panel big honking knob, just a slotted pot on the back. nothing is exactly balanced, especially ears. oh well.

I put a simple bass boost switch on all my DIY Amps. the circuit is within the feedback loop so as to not require more circuits. and when switched off the circuit is compleatly devoid of any Reactive components at all.

I think that with Headphones more so than Loudspakers need some type of EQ most often bass Boost. but the EQ on most portable CD players are lame and really do not boost the bass but just reduce the Midrange. i am sure there are exceptions. I am not a big crossfeed fan but EQ is a must for me.

 

[daredevii]

So where can I get one?

 

[dougli]

Are you looking to use an EQ at home, or for portable use, or both?

 

[PinkFloyd]

YES.

The B-Tech 928 has tone controls. It's a £29 head amp that sounds like a £200 amp after a few inexpensive tweaks.

See the tweaks at my site: http://freespace.virgin.net/rock.grotto/index2.htm click on "Headphone amp upgrades page"

The B-Tech is a SUPERB amp for £29 and is an absolute miracle after spending around £10 on components.

I'm looking for something portable, dougli. At the moment I'm trying to decide between the super mini 4.0 and the Airhead. And how much is 29 pounds?

OK, I'm no help with portable EQ's because I've only researched and used home/studio units.

 

[Orpheus]

many of the professional headphone amps have EQs built in, including versions by Behringer, and Redsound... but i doubt anyone here would like them.

Orpheus:

Why do you say no one on Head Fi would like the Behringer or Redsound headphone amp w/ tone controls or equalizers? Lack of power, not a good sounding op amp, poor design, poor components, etc.? Have you listened to either?

Thanks
