i havent listen to much stuff. I've only listened to what i've owned. My main headphones with the most head time is the hd650 and hd600, both are being run through the valhalla2 with genalex gold lion tubes(not a fan of stock). I also have the k7xx,400i and soon the thx00 which i run them out of the m9xx. Since i got headphones of varied impendence im thinking of needing something versatile. This is the order of what i like best.
Hd650-valhalla2-m9xx
Hd600-valhalla2-m9xx
400i & k7xx-m9xx (tied)

Initially i had wa6se and mjolnir2 on my mind but after some looking around im uncertain of what should my future upgrade be.

With that budget I would go with either Audio-gd DAC-19 or Schiit Gungnir Multibit. Regarding amplifier I have good experience with Cavalli Audio and Eddie Current.

Check out my new Fiio sellout setup: X7 -> K5 -> HD 650! Anyone else doing this?

Does the X3 v1 go into that dock?

I believe it only supports generation 2 of both X3 and X5. I happen to have both of those, but I wouldn't be able to use them. It doesn't matter to me now since I'm content with my X7.

if somebody knows why and the possible benefits of doing so, I'd be interested.

I'm not a technical guy whatsoever but here's an example that was very noticeable for me. Listening to Snowblind by Black Sabbath (FiiO X5ii coaxial out>Bifrost 4490>Vali 2>HE500) with V2 in low gain. I really enjoyed the clarity and detail of the song but wondered why the bass was so thin when it occurred to me that perhaps I should flip the amp to high gain. So I dialed back the volume knob, flipped it to high gain, made another minor volume adjustment to earball it the same volume as before the gain switch and then hit replay. There, the bass thinness was gone, bass was present in perfect measure.

shiit writes this on the vali2 

Output Impedance: 1.2 ohms in low gain mode, 5.8 ohms in high gain mode

if I go treasure hunting in all my resistors, I might just find those values(minus my amp's impedance) and try to measure the difference in the bass. but I wish those damn resistors would be labeled with more than desaturated color rings. :angry_face:  if I get lucky I'll try, but don't be too surprise if I just give up because it wouldn't be the first time I gave up on those damn resistors.

but anyway, while I don't know if the bass increase from that impedance change would be significant enough to be audible, it certainly goes in the direction you're mentioning on the hd650 with its impedance bump in the bass. higher impedance will mean more bass(the rest is attenuated, but the result is the same) audible or not.

 

it might be interesting to try and see if after adding some resistors to the low gain to match the high gain, they would still sound different?

 

 

 

for the other 2 fellows, I couldn't find anything for asgard2 and liquid carbon. does it mean they have about the same impedance? or is it only that it's not documented? IDK.

I'm sure there can be more to it than just impedance, but again I'm not knowledgeable enough. I just noticed that impedance changes with gain sometimes for some amps, but it's merely one more possibility. I wouldn't claim that it's the reason for all sound differences when switching gain. but if it is the main cause, then it can become a matter of analog EQ, not a matter of better signal fidelity. so we would be talking about taste instead. my post was mainly about trying to get the best SNR/dynamic range when I suggested to stay on low gain if it's loud enough. and even then it might not be true for all amps and all gain settings. just a general rule of thumb. I'm guessing that asking to your respective manufacturer would be where the best advices are.

Lol that's a pretty tough question. A lot of the fun is trying a bunch of gear and seeing what you enjoy.

Tried the high and low gain setting on both Asgard2 and Lyr2, there is a slight difference in the bass, a touch more in the high gain setting but its not consistent across different headphones.

 

HD-650, HE-560 and SennGrado its a very slight increase

 

HD-700, DT-990 (250), SRH-1840, Momentum no increase

post #32456 of 33771
With so little output impedance difference between high and low power it's surprising that differences can be heard. If I go from just above zero to 120 ohms output impedance on my Polaris, the effect isn't huge.

I womder whether something else is going on with them?
post #32457 of 33771

sure, I wouldn't expect much of the all affair going from 1.2 to 5.8ohm would most likely stand in the 0.1 to 0.3db area of added bass. I hope I didn't give the impression it would be anything massive. I did question if that one cause would be audible. after all we're expected to stay below 1db of variation as long as we keep a good damping ratio. which is easy with a 300ohm or more headphone. ^_^

You will have many, many options....which is best all depends on your ears.

 

Have fun, should be a wonderful journey with that budget.

That bass when you crank up the volume, I love how it rattles my ears a bit:L3000:

Haha... have you tried Audeze headphones? Leather pads tend to offer very satisfying bass. 

 

I would also recommend the ZMF Omni's for well articulated, satisfying bass:

The 650's have nothing on them, with respect to sub bass.
