[LIST][OPINION] Amp recommendations for Fostex/Denon Headphones. - Page 4

Poll Results: What do you think of amp recommendations in general?

 
  • 12% (17)
    Disgustingly not thought out, just recommended from the single amp they have tried
  • 13% (19)
    Poorly thought out, mostly blind brand loyalty
  • 41% (57)
    50/50, a lot of zealots but about the same number of helpful recommendations
  • 11% (16)
    Mostly people here know what they are saying
  • 15% (21)
    WiR3D is a zealot.
  • 6% (9)
    I disagree with you most things, people can recommend from there own experience, even if it is just the one amp that they own.

That is correct.  I remember reading a thread where the output impedance was 32 ohm but never confirmed.  I usually use mine with Grados and Ultrasones, but was curious about the specs.

 

How about this:

 

Power Output-

 

650mW/25 ohm

160mW/100 ohm

 

Output Impedance: 1 ohm

 

And this:

 

 Output impedance:  7 Ohms. Sensitivity: 0.3 V for 10 mW output. Output power: 100 mW. Frequency response: 10 Hz-20 kHz -1 dB

 

 

I own these amps and curiosity crept in with the Denons and this thread and the amps I have.

 

Thanks

The top one... SNR figures and Voltage or current figures would be nice, and the bottom one, mmm, the bass will be bloated and sloppy but nowhere near as bad as the LD

WiR3D, you're killing me...lol. I vowed over three years ago not to listen to the equipment anymore and concentrate on the music...

Second one is my Mapletree Ear+HD. Has Low Z and Hi Z head outs. Been a while since I plugged the Denons into it.

First one is the NFB-16. I was comparing it with the Denons last night vs. one of my portable amps and like I wrote before it spanked it. Bass is tight and defined, speed was accurate. I like to throw on some blast beats to see how phones hold up. On my portable, you can notice it was trying to catch up with it and sort of sluggish.

I have four head amps that I like, with output going from 0.05 ohm to 220 ohms. I've never noticed big bass difference between them. A few years ago, I even used a 80 ohm preamp to drive my cans and the result was pretty good. You've convinced me to test them all again and pay attention to the bloated bass thing.

The D7000 I heard on a meet last week sounded pretty good with my Lake People G100 and Audio-GD NFB-17.2. Lake People/Violectric aims at having low output impedance and the pre-gain switch gives a nice range on the volume pot.

I did the "stairway" like I call it...lol

Headout from a couple DAPs for a while, then portable amp for a while then NFB-16 for a while. Then reverse the order.

@HeatFan12

The AudioGD stuff on paper all looks good for the Denons, I do wish someone with the C2.2 would pop by already.

and the Mapletree I gather the 7ohm output impedance is on the low Z? 

 

@Headdie 

Lol dude I'm sorry, but it had to be done, remember the impedance thing is not about subjective sound signature, its about response, the bass response being the most notable, and if you have a good ear microdetails. The issue comes in eliminating the amps sound signature as some amps just have bloated bass to start with. 
 

For me it was easy, since I have an STX, and the faux impedance decreasing adapter I made clearly yielded a difference. 

 

@Anda 

Did you compare it with any other amps for frame of reference? Mainly some that I would not recommend.

South Africa, you da man OP...Cheers!!!

 

A soundcard? Are you serious?  Please tell me you have a dedicated dac and amp to plug your D7000s into before comparing.  A soundcard is a soundcard no matter how you slice it.  It is good for gaming and movies with a headout so you could enjoy your games and movies.  I run 7 computers through the house, three with STXs and the STX could not drive me properly to the corner CVS pharmacy for smokes let alone any of my headphones.  I once thought my 0404usb headout was the best thing since sliced bread until I purchased a headphone amp.  Forget the specs and plug those Denons into something music worthy sir.  You're very knowledgeable but thinking too much...

 

At the top of your "NOT RECOMMENDED" list should be the STX...lol

 

You bash the LDI+ in favor of the STX?  Are u serious?

 

Good luck in your search for the perfect amp for the Denons...Enjoy!!!!!

 

Cheers!!!

I'm finding the built in amp of the Fostex Hp-p1 works really well with the D5000. My D5000's had sat on the shelf for months until I tried them on this amp. I prefer it even compared to my far more expensive Apex Peak which supposedly has a 1ohm output impedance and in theory should do well with the Denons. I find the same thing with the AKG K550, even though I have a much better source feeding the Peak I prefer the Hp-p1. With the HD800 it's a totally different story.

:facepalm: its going on the list, thats what eventually lead me to this crusade, The STX is not the only thing I have plugged it into, but after reading all the ****ty recommendations and the disappointments I created this thread to rant, now its become a source of info. I think I am going to buy the Yulong A18, next month, that or save up for a long time and try get the AudioGD master 8.

I am interested in hearing people's impressions on DIY amps with the Denons.  Anyone listen through a SOHA II?

+1 I'm also interested. 

And while we are at at, can someone give me its output impedance?

 

Same story with the Minimax.

I forgot to mention the E9.  It has been recommended around here a lot, but it is basically the same as the STX on the main headphone jack.  10 ohm output impedance on the 1/4" jack, 43 ohm on the 1/8" jack!

post #60 of 431

For high impedance headphones like the HD650s the E9 is acceptable. But not with sensitive low impedance cans.
