Currently loving my setup. Looks very lovely.
This is so stressful.
I have about $450 to spend total. Is there any decent setup that can be had for this price, with or without the Q701? I would rather not buy used because i live in canada and it is difficult with shipping and stuff.
Chicolom - Have you guys heard the K/Q 7xx with a tube amp?
Not to add to your stress, but I'm very happy with my JDS Labs C5 driving Q701, K550 and Grado SR225. It runs $189. They also have the O2 ($129) and cMoyBB v2.03 Headphone Amplifier ($59). Reputable shop with attention to detail. Free (still, I think) printing of pretty much any design on the C5. It's portable and can drive a lot of different cans. Full specs, etc., on the site and the owner's blog.

The E17 is nice, especially with all the options it has and the low price. The Q701 does scale well with better gear though. My ODAC and my vintage Pioneer SX-750 do a much better job. The SX-750 is a better amp, and the ODAC is a better DAC.
You only have the K712 now right? Or still have your Q701? I know you have Q701 pads.
Just the K712 and angled pads.
Maybe the changes with the K712 and Q701 pads are much different than with the Q701.
I doubt they are that different. It's the same mod being applied to very nearly the same headphone.
Does the K712 itself with Q701 pads have more bass than the stock Q701? That may explain some things.
Only very slightly more.
After two weeks the soundstage for me is much more spacious and more accurate. Better depth as well. This is the 2nd best improvement.
After two weeks? If there is a change in the soundstage, it's minor IMO.
If you used a K712 for testing (with Q701) pads I have an idea why there may be differences..
There is no stock outer grill foam and the K712 grill is more open. This would probably give much more bass than the Q701 with the foam installed. This may explain why the mids are different for you.
When the modded q701 has no outer grill or foam the low bass is increased a little and it's audible.
With my Q701 I never heard much difference between the outer grill having foam or no-foam.
Mids are definitely fuller for me. If mine sounded less full or more distant I'd have reversed it on day one. Not a huge difference. Not any more forward or recessed for me.
Yeah, I'm not hearing any fuller mids :\
Now maybe you really have the Q701. If not you could try to re-create the modded Q701 grill by putting outer foam inside the grill. The outer grill and foam with the modded Q701 is VERY important.
The K712 won't ever sound just like the Q701. I did a lot of comparing between the K712 and Anniversary (which sounds 99% like the Q701) and the K712 was always different sounding regardless of any pads or anything else. Neither of them have any foam under the outer grill.
BTW for ME there was many more improvements i've heard. It actually now sounds more transparent, which is bizarre. Clearer too and not due to any more treble and less warmth. It almost reminds me of my DJ100 with M50 pads. That thing has very full mids and they're so crystal clear with the best recordings. I get that now with my modded Q701 too. This is with the Modi/Micro Amp (both transparent IMO).
OK. If you hear a bunch of miscellaneous improvements I won't try and argue with you. I have to be honest with my impressions though, and I personally don't hear them.
Strangely for me my modded Q701 doesn't have much of a big boost in low-bass. Probably not more than 2db.
It's not a big boost, but it's probably the most audible difference I hear from the mod. I would say mod one side and not the other and listen to those very low frequency tones I posted. The modded side was producing an audible signal at 18hz, 16h, etc. where I could barely hear it on the un-modded side.
On the question of amping - for another opinion. My understanding with the X701 series - is they require more current than voltage. I've owned the K701 and Q701 - currently own the K702.
Current amps are Audio-gd NFB-12 (SS) and LD MK IV (OTL tube)
The K702 (and for that matter the Q701) actually sound better to me out of the NFB-12.
This may vary with individual tastes - and I guess OTL vs hybrid (where a hybrid may have tube colouration, but SS current).
The other thing I've noticed (especially with the K702) - the more current, the better they respond. The bass does seem to lose a lot of control and impact if they are under-amped.
My 2c.
ODAC is one of the best purchases I've done since I entered the audio world, together with the Q's.

Well, it's not like the difference is so large that it makes it sound like a K501 or AD700, but it's really a nice improvement. I would say for me it's a little greater than minor. It brings it closer to the K701's soundstage but without anything sounding too distant or losing the full mids or good center image. This is so far only the 3rd headphone i've owned where it felt like the sound was almost speaker like. The "out of head" sound was more common on the K501 I had though. That thing kept making me look behind me like something outside my headphone was happening.
With my Q701 I never heard much difference between the outer grill having foam or no-foam.
I've compared this many many times and it's really (stock q701 with foam and no foam) subtle. I like it with the foam installed stock because it reduces the soundstage a tiny bit and makes everything sound closer. I know this is weird, but that's what I hear. I wish I could remember some examples of songs. Here is one interesting test I remember. You can take really really harsh recordings with annoying upper mid/treble peaks and it's actually less bothersome with the foam removed. Not sure why and I guess this would vary depending on what frequency it was.
On the modded Q701 for me the difference is much greater. There is a tad more bass than I'd like with foam removed so I keep it installed. You actually get more present low bass with no foam and no grill. I bet the K712 modded is closer to that sound but maybe not.
I doubt your K712 is now modded still but seriously try a tiny piece of foam or paper towel inside the outer grill. I bet that's the trick with the K712 and even the K702.
The K712 won't ever sound just like the Q701. I did a lot of comparing between the K712 and Anniversary (which sounds 99% like the Q701) and the K712 was always different sounding regardless of any pads or anything else. Neither of them have any foam under the outer grill.
Oh I know. I should have worded that better. I just meant that adding a piece of foam would get you CLOSER to the modded Q701's sound. This is obviously with angled pads and the mod installed (well duh).
I mentioned this a few weeks ago but I bet there is a good chance this might not work as well with the K702.
One amusing thing to hear is to have the mod in place and then remove the foam behind the pads. You actually get bloated bass and not LESS bass. I was really surprised.
OK. If you hear a bunch of miscellaneous improvements I won't try and argue with you. I have to be honest with my impressions though, and I personally don't hear them.
No problem and I bet adding some foam would make it sound slightly different even though with stock Q701 there's not much. I think the K702 and K712 grills let the driver just get way too much air. I guess it's all about getting the perfect amount. I bet for the K712 a piece of tape over the hole that's slightly open would be good. I believe that's either 3M Transpore or Micropore. Whatever one was fairly open.
Some of my impressions of the mod are a little off the usual consensus but that's OK. My brain is now so adjusted to the sound that it now starting to all sound normal. When I give myself a few days off it almost sounds like my HD-650 on steroids.
Really just can't understand why my modded Q701 sounds clearer. In comparison the stock seems like it almost has an ultra tiny veil to the sound. I mean it's still pretty clear but never was crystal clear to me.
It's not a big boost, but it's probably the most audible difference I hear from the mod. I would say mod one side and not the other and listen to those very low frequency tones I posted. The modded side was producing an audible signal at 18hz, 16h, etc. where I could barely hear it on the un-modded side.
I think the low bass I'm trying to hear is probably WAY to low to be really audible with the mod. I guess the mod can only do so much! It's funny hearing weird bangs on the floor and other random weirdness that never even registered before. There's stuff on my Tony Bennett CD that even requires very good low bass extension. Hahah, never would have imagined. They would always show up on my KRK KNS-8400 and DJ100 but almost never on the HD-650 and Q701. Well, now they're there. Someone banging on the floor is sub-bass?
I'm trying to figure out what frequencies all the low bass rumbling sounds are at in Fallout 3. Definitely not mid-bass but no real change with my modded Q701. On the DT-770 Pro 80 I got a nice ear massage. I think on an open headphone those low-bass sounds I'm referring to are actually SUPPOSED to sound more distant but I was fooled.
No headphone has ever gotten close to how that game sounds on my DJ100. Maybe someday I can find a headphone that has fuller mids than the modded Q701 and HD-650 but yet no lack of treble. Maybe HE-400, but I don't know if it has really full mids or not and that's totally off my radar.
BTW you ever listen to a headphone and feel like you can feel the bass in your toes? This is extremely rare but happens sometimes. Must be imagining things. I don't mean on a bass heavy headphone. Heard it once on my KRK 8400 and everyone tells me that's bass light! No way!
Oh one last thing. Did the modded K712 and stock pads have way too much bass or did you just check it with Q701 pads?
When I jumped from the DAC on the E07K to the ODAC I said... HOLY COW! So I imagine you will notice the difference even more than me. At that point I was already bypassing the amp on the E07K and using the O2 so I know the change was the DAC. I noticed and improvement in the bass details, but especially in the upper mids and treble. If you are curious about it you can try the Sabre first that is much cheaper and some people reported to be pretty similar.
I think that was the moment in which I unleashed the full potential of the Q's. I don't mean to hype the ODAC either, but I think is a good buy for sure.

Another interesting thing is that on my E9 I could barely tell the difference between the ODAC and MSII. Wow, terrible. Good job E9To hear the difference it took a better amp. Had to do that with the ODAC and Modi too.

I bet they are. I don´t think anybody proved the ODAC was colorless (unlike the O2). I chose the ODAC just for convenience in doing one package with the O2. As I said, the Sabre is apparently at the same level as well, but around 50$ less. I just didn´t want to take the chance in my first DIY proyect. I might be trying variances in the future.
