I have yet to experience a headphone that can throw a proper soundstage to make it seem like the image is coming from the front. While the Denon/Fostex are closed, they still IMO offer realism. Listening to live events, the reverbs are perfect to match what it sounds like to be there. I couldn't get that with Audeze.

 

Having said all that, speakers > headphones, any day of the week. That's why I got rid of LCD-3 to fund speakers and then get a TH-600 or TH-900 on the side to replace my D2000 eventually. No need to carry separate amps or DACs. The Dangerous Music Source will drive both headphones and monitors with a good dac and amp. Not to mention solid features.

 



If you have time you can visit Bay Bloor Radio, I bought my 2nd HD800 from them at Black Friday special price.
It really come close to the speaker experience IMO. You can ask them with HDVD800.

Also I know lot of people hate Grados, but PS1000 is just another headphone that sounds like speaker, something really nice about. You can also audition at Bay Bloor Radio. smily_headphones1.gif

 

In my mind, I had a plan to eventually get a HD800 along with a subwoofer running in the background. I think that would get you the closest to speakers. Although speakers will remain speakers.:D

If you're trying to replicate speakers with headphones and a subwoofer... why the heck don't you just use speakers?

Lol true. Maybe try zo2?

LOL I am getting speakers. This was just an old plan. I used to do with Audeze's and Denon's. It was quite fun for ships and giggles :D

Yep.
That certainly does sound kind of sideways......rolleyes.gif

And headphones will remain ear speakers as Stax calls them.

This is a little off topic but for you tube amp guys I put up a web page tube bias calculator. It has a database of the 29 most used power tubes.

Oh, I do love crunching numbers!  But not enough to buy any tube gear!   :D

Pardon my newbie-ness here but I've got a question for you amp inclined folks. I've got a Hifiman HE4 that is almost inefficient as the HE6 I'm trying to run on the speaker taps of my Tubemagic A1. Through the HP out in the front of the A1 it sounds OK but that's with the knob maxed out and some recordings are still to quiet. Running them out of the speaker taps, they get to decent sound level but the sound can become unbearably bright.

At first I thought it were the tubes I was using (Raytheon 6AK5) so I switched them to a warmer Mullard. Now the sound difference with the Mullard on the HP out and speaker taps to Pioneer speakers are warmer. With the HE4 plugged to the speaker taps it is still unbearably bright/annoying to the point where extended listening would cause headaches.


-My question is, am I doing something wrong here with the HE4 out of the speaker taps?

-Does the chain need resistors in line to make the sound not overly bright/unbearable?
  It seams speakers through the speaker taps benefit in warmth with warm tubes but not the HE4. Which leads me to the next question..

-Is it the 0.1% THD rating on the speaker taps making it unbearable with the headphone?


Appreciate any input on this. I just want to know if it's the nature of the amp or if I'm doing something incorrect.

The amp uses a LM1876T chip for the output. If the chip is using bridged mode it is not a common ground amp at the speakers outputs. How are you connecting the headphones?

I've got a balanced cable to a female 4 pin xlr adapter. From the adapter it goes to 4 separate wires which goes directly to the speaker taps.

0.1 % distortion is in audible! sounds like you do have the headphones hooked up properly.
Adding resistors should not make the amp sound less bright.
I don't see why you should have any troubles.....
...OTOH, some recordings are so bright you wonder what they must have been thinking when they mixed and mastered the recording.
I have a few recordings that are almost unlistenable unless I EQ them a bit.

The sounds is excruciatingly bright out of the speaker taps with the he4 though vs the Pioneer speakers that sounds warm (with the Mullard tubes). I've tried many albums with the same result. Even through the Yulong D100, which leans to the bright side of neutral, is bright but not excruciating like the a1 and he4.

Then I'm stumped!

I have no idea why the A1 + HE4 are misbehaving!
