Well it gave you a bit more presence and treble and made the d600 a bit more U shaped.

Ah ... They even sound good if you sit on them!

The D600 changes quite dramatically from my Ifi Micro. For the first time, I plugged it in today and it really opens out. Bass is quicker and so doesn't dominate as much but the sense of space is really very good.
I was listening outside on a bench with no amp and just came in so I thought I'd try it. Very different and the d600 sounds like a switch has been turned on. It really comes to life; dramatically so. The treble sparkles more and it sounds way more open in comparison to the headphone out from the Fiio X3.

I haven't compared directly yet Simon. The Micro has A sharper edge plus the 3d gizmo. The headphone just had more authority and isn't as flabby sounding as it is from headphone out.
It actually sounds extremely good. The change is very noticeable in that there is more 'air' in the sound. I have no idea why, other than perhaps having a lot of power gets it more controlled, so that it's not as flabby.

I have no idea why, other than perhaps having a lot of power gets it more controlled, so that it's not as flabby. i would have thought the other 2 amps would have equal power? how about trying the ifi as a dac into the other amps also? i am tempted to get the ifi, myself, but funds will be tight for another 2/3 months yet. i do keep an eye on ebay just in case a bargain comes up. the only problem with a used one is that you cannot be sure it was charged properly initially.

Tbh Simon, I wouldn't think many people would want to sell them. They are really good. I have used it as a pre amp into some active speakers and when the SeNNator arrives, I'll send digital into it and send it to the SeNNator for the HD650 which I think is going to be stunning with HQ files.
Maybe some will come on the market with a v2 on the way. I wouldn't sell this or the Ember and Polaris. They're all such good amps. The treble on the Garage amps is slightly softer than the Micro, so the Polaris for instance, would hone the edge off the top. It imitates a valve sound so isn't really the same thing. The D600 sounds really good from the Polaris as well tbh. If anything, it's a bit weightier.
What surprised me was how the d600 is sensitive to an amp. It develops more space and clarity. We tend to assume that low impedance means no amp is necessary, but that's really not so. They take more current so bass does need some power behind it. I think better low impedance headphones show it a lot more. Grados don't seem to mind, although they work IMO, much better from high output impedance.
There's more to the matching for really refined sound, I think. Even with low impedance headphones. (If they're half decent)

i think the "v2" you refer to is actually the "idac2" not the "idsd2"?

Oh. Sorry, I get very confused with the numbers and models from Ifi. I nearly bought a Nano Ican by accident before Javier pointed it out to me!! Mind you, I have one of those as well. The idsd is streets ahead, even as an analogue amp.

I measured and listened to Rabbit's D600. My findings are found here: diyaudioheaven.wordpress.com/headphones/denon-ah-d600/The short version for me is this: The Denon AH-D600 is aimed at the portable market. Boosted bass helps here. Boosted treble may not be an issue when listening to Youtube quality recordings. The bass is (tastefully) boosted. For pop music it has a healthy boost. For better recordings the bass level is way too much and after an hour or so became nauseating for me. Treble level is too high to be called neutral and will cause listening fatigue after some time. The mids sound good though and the slightly dis-attached bass makes the listening experience pleasant… that is if you can stand the elevated treble. I might try to do something about that …. When I do it will be posted.

The raised bass and treble helped with speech and the bass is wonderful for bombs with no sub woofer needed!! I've often thought that it might have been designed with movies in mind. If anyone wants to buy it, just make Frans an offer!!!

I have been tinkering with the D600. It has one of those famed Foster biodynamic drivers so should be able to perform a bit better. From stock (way too bloated bass and fatiguing treble) to modified... It was a bit tricky to get L and R the same... turned out to be a slightly different leak near the wiring feedthru. Now the headphone measures (and sounds) like this. I was wondering how low it would go below 10Hz so made this plot as well. 7Hz flat... Sounds quite good actually. Not far off from the TH-X00... The treble is a bit less refined than the TH-X00 but the bass is 'tighter' and full.

Quite an amazing change, Frans. A headphone that goes all the way down to 7 Hz? They're big on the head as well aren't they? An odd looking headphone. I see that Denon are creeping back to the old cup style again now so you never know, they may produce a nicer sounding headphone that doesn't need to be changed so much!!

It was just a matter of sealing 1 hole inside the cups (a port) that causes the boost and discontinue in the bass. Was put there on purpose probably because they did want the 'beats' market and 'added' overblown bass I reckon. it doesn't have hifi-high end looks so must be aimed at that market. 2 plies of toilet paper were needed to tame the treble. That was all. Getting L and R to match was a pain and took me several hours. You can already see a L-R difference in the stock headphone so it wasn't assembled carefully from the start.
The pads are comfortable but not suited for big ears. Model is a bit futuristic (aimed at youth ?)
The biggest problem for this headphone now is the cable. A stiff gardenhose cable with cloth covering. Too long for portable use, too short for desktop duties. And above all... VERY microphonic.
A supple and short cable would be better. Fortunately it has standard connecctors so a replacement cable should be easy to find.
The sound quality is worth it. Only slightly lacking in finesse. But most Foster bio drivers have someslight weirdness in the treble. Good with bass (now at least) and mids which sound warm, lush and full.
