I wonder how many people skip out on the Micro due to it's size. I can't wait until I get some people commenting about how my headphones are underamped if I don't like them normal_smile%20.gif Based on how small it is, many people might wrongly assume it's a portable! This thing is tiny! Half the size of the E9 unless you add in the power brick.

 

This Micro amp seems even more powerful than my E9 and Asgard by far. If I use High Gain (Medium is enough) for my HD-650, I could probably blow up my headphones if I wanted.

 

It does kind of bring forward the upper mids a tad, but not too badly. It makes most music a little more fun to listen to. I don't think say a W1000X or an ATH-AD2000 would be a good match for them, but maybe. I bet the Denon D2000/D7000 would sound great on these.

 

Yesterday I was comparing the mids on my K702, HD-650 and K601 with female vocals. It was a bit confusing. On my HD-650 female vocals sound a bit more forward than the others, which I like. This seems to go against what I heard previously before I had the new cable and amp. I'm not complaining. With my setup my silver screened HD-650 isn't too laid back or boring. Just about right. I still don't find it to be a detail monster, but I don't want that. Still has enough detail for me. My HD-650 sometimes can't even pick up recording hiss on any amp. That could be a positive or negative.

 

K702 was strange because often vocals would feel quite distant and other times they were more forward than before and more in your face (depending on the recording). Perhaps the K702 is just more accurate to how it was recorded. Who knows. I imagine this is true.

 

The K601 mids are somewhat more forward sounding to me than the K702 with nearly all music and never randomly sound distant like on the K702. I think maybe it's not as accurate as the K702. Perhaps the K702 is more true to the source and how it was recorded. It's just strange.

 

My K702 is nice now, but it's treble is an issue. I've been burning it in non-stop to see if it gets tamed. With brightly recorded Japanese pop music it can sound a bit un-natural on the K702 at times.

 

After a few hours of comparing them I prefer the HD-650 and K601 for 90% of my music. Still prefer the K702 for specific genres, but nothing wrong with that. I love soundtracks and ambient music with the K702. It's also my gaming and movie headphone. I HATE the HD-650 for gaming and movies (HD-600 is ok though). It'd be nice to have a headphone for everything, but that's nearly impossible. The closest I've come to a do everything headphone has been the HD-600 and HD-598. K601 is fairly close to that also.

A few things guys:

 

1) After a certain point, quality of the amping matters more than the power. This is especially (and obviously) true for cans that aren't very hard to drive, like the HD6x0.

 

2) The HD650 scale higher than the HD600 and will improve more from component upgrades BUT, the HD600 sound better from lower-end equipment and it's easier to find a synergy with them.

 

3) Just because an amp can pump out high volumes with a headphone doesn't mean it is driving the headphone well. In fact, none of my headphone amps (or soundcards) have ever had trouble achieving ear-piercing volumes. Some of them just sound mediocre and others sound far better regardless of the volume. Listen to how good the headphone sounds on the setup, not how loud it goes, to gauge the amp's worth.

I agree, the Micro Amp is one under appreciated piece of gear...just 'cause its small doesn't mean that it can pack a whollup. I much prefer it over the FiiO E9.

HeadRoom amps in general don't seem to be very well appreciated here on head-fi. Maybe its the price, my full size amp/dac did cost 800 bucks. It is so worth it though.

Convince me that my plan to make the 650s a complementary can to my MS2i is a good one!

Give us the whole story on these cans!

Yeah!


I had my HD650 for 2 years and i sold it off to a friend of mine cause i was pretty sicked of the sound. I bought DT990/600 ohm instead, to pair with my bijou tube amp. The pairing is awesome! Great detail, highs, good distinct bass. But the one thing i miss bout my HD650 is the lush mids! I miss the hd650 with female vocals! i practically dream bout hd650 already.

 

So here i am, going to grab another pair for hd650. It's gonna be a keeper this time!!

 

I've heard of MS1 and you bet, 650 is going to be a good complementary can to ur MS2.

Also because of the 1/8" out. With the 650 I had to use an adapter, which was not too bad with the stock cable, but when I got the Cardas, which is heavier, then the 1/8" connection really sucked.
 

 

post #3082 of 36885

Oh yeah that's the one complaint about it I have so far. Using an adapter is kind of annoying. I actually expected this amp to be much, much bigger. I actually imagined it to be at least 3 times the size of the E9. They sure aren't kidding when they call i the micro amp! I wonder if there is an even smaller amp out there that's even more powerful?

 

Using a nice new cable and having to use say a Sennheiser 1/4" to 1/8" adaptor with that cheap wire on it would annoy the heck out of me. Luckily my new cable I built has a 1/8" jack on it. Using a larger metal adapter seems like it'd wear out the connection after awhile due to stress.

 

I think I might build another cable. I heard in some forums that the Canare wire adds extra warmth to the sound. I didn't notice this, but it could be true. I guess if I'm OK with the sound than it doesn't matter. I also read that the silver plated copper seems to offer the most detail.

 

Has anyone compared Mogami vs Canare cable for the HD-650? Probably not, so I guess I can be the first to try both. At least now I know what I'm doing when building cables, so it'll be less time consuming.

 

At this point I'm loving my new HD-650 Canare cable that I can't imagine going back to the old one. For only being under $40 it was totally worth it. The only thing that made it a little more expensive is those overpriced Sennheiser connectors. I'm just glad Cardas didn't decide to sell them for $40! Some websites have them for $13. It's kind of annoying how shipping the 1oz item still costs $8.00. I wish it was easier to find a place that sold BOTH the wire AND the connectors. It'd be make it easier.

 

Making new cables is addicting. Next week I might make an extension cable out of some Mogami cable. Sure, you can get them for $2.50 at Monoprice, but what fun is that? For someone that has very little experience with a soldering iron or build cables, it's fairly easy to make them and i'll get better at it.

 

BTW never buy a Radioshack extension cable. I was forced to use one today during work and it seems to degrade my sound quality severely. I thought my new headphone cable build was bad but it was the extension cable that shorted out every few minutes. I've now purchased a total of 5 things at Radio Shack that have died. Bad luck or something I guess. At least my SPL meter is still going after about 10 years.

 

Also, I bet Canare wire would be a perfect match for the AKG K702.

If I could just have the HD650 sound on a deeper, wider stage.  It'd be my end of the journey.

Works great, doesn't affect the sound and very well ergonomically designed to not get in the way.

My HD-650's soundstage definitely got larger when I upgraded my amp, but I wish it had the huge soundstage of the HD-598. If someone says the HD-650 can have the same size of soundstage as the HD-598 then I am going to say you are lying normal_smile%20.gif

 

I find it hard to believe that Sennheiser intended the HD-650 to have a huge soundstage anyway. No problem there.

 

For me the largest soundstage I've heard is the AD700, then the K702 and HD-598. People always said the ATH-AD2000 had a small soundstage but I felt it was larger than that of the HD-600 and HD-650!

 

Personally I don't need a huge soundstage, but when it has the mids of the HD-598, it's kind of addicting.

Unfortunately I'm back to square one with cables. I've now switched back to stock. The Canare cable I made offers more detail and more mid-bass and perhaps better quality bass, but it's not a good match for the HD-650. It took me several days to really get an idea of how it really sounded. I often get the feeling that it did improve the mids a little. Combined with my new amp, that was a good combination!

 

The negative is that whatever it adds, also seems to reduce the sound clarity. It's just not as clear sounding as the stock cable. The main killer is that the Canare severely rolls off the high end. It will totally smooth out the treble on the HD-650 to me. It made very bright recordings much easier on my ears. I like this, but I don't want my headphone to tame my music if I can avoid it.

 

I added back in the stock cable and the sound was more clear and there was a lot more treble. Some songs just didn't feel as smooth as before when you listened to them with the Canare. I guess in the end the Canare is nowhere near a neutral cable.

 

I guess I need to find one that's perfectly neutral and offers the clearest sound. Maybe the Mogami will work. I think I read somewhere that for sound clarity and detail, silver plated copper is the way to go. Silver is tempting, but these are bright enough as it is and I don't want them to get even brighter than they already are! Maybe the Canare would be good for my K702.

 

I also removed the Canare cable from my Sextett today and the sound clarity shot way up and it's like I have a new headphone.

 

Still love the HD-650 now with my new amp. Today I tried it again with movies and games and it's not as bad as before, but I still prefer my K702/K601 for that.

 

Guess I will try Mogami and hope it's neutral and doesn't change much. There's also Belden, Gotham and Redco Quad cable. I don't feel like spending $70+ on cable right now though.

The "clarity" of the stock cable is just the etched treble that's part of its presentation. Listen closely, your copper may sound thicker and warmer but there are micro-details there that aren't as well resolved through the stock cable.

 

It sounds like you need to give the DHC nucleotide a try. It has the characteristics you like but presents a more balanced signature. I wasn't initially too impressed by my DHC Molecule but for me it was a matter of finding the right synergy with the hdam in my dac. I'm not sure if it's undergone burn in, but I swear it's changed significantly for the better the last few weeks as well. Now when I switch back to stock it sounds tinny and cheap, without the resolution and width of soundstage.
