I wouldn't avoid all bugle boys necessarily, sample variation of used things are wide, it's just the two Amperex (regular and bugle boy) I tried have not been satisfactory. maybe it's a tast thing. Expect more impressions tomorrow, I'm going to spend some time balancing the two channels.

 

Thanks, Evshrug, that's what I like to hear!  Out of curiosity, are you using the Voskhod "Rocket logo" 6N23P?  I know the Rockets are highly thought of, esp. for the price.  Can't seem to find any atm.

 

The Bugle Boys Brent Jessee has are NOS, so not technically used.  He/they seem to go to a lot of trouble identifying, testing and matching unlabeled tubes.  He definitely has a passion for it all.

 

Thanks again.  Both pairs will be in on Monday, so eventually I'll post some impressions of how the Q701 fares with them.  I'll probably demo them while I'm modding the HE-500 pads.  I don't want to forget about the Qs!  ;-)

Upon getting back to my house, I'm surprised to say I was terribly disappointed by how different the Q701 sound to the one I tested in the showroom, with the same AMP/DAC. Sure, I notice something changed after about 8-12 hours, but it was not before 3 days that the changes become apparent and after 7 days the changes become obvious. I questioned myself earlier, did I, or did I not made the right choice with my deviation? I guess it is safe to say for now that I don't really care about it anymore, all I know is I'm deeply enjoying this cans.

 

As much as I like to knock myths like "burn in" I've always noticed changes with the K701 and K601 drivers over time. I also prefer the K701/Q701 to the DT880 and HD600. I think more than anything, it's the soundstage that's most impressive. Great for live recordings as well!!

Hi folks,

 

As a long time owner of Beyerdynamic DT990 Pros, I am bored with the recessed mids and want to try something new. What I prioritize the most in headphones are wide sound stage, clarity, and naturality. From what I read, I understand that Q701s are a good choice for my first two priorities. Given their heavily discounted price on Amazon, I am about to order one, however I have a few questions.

 

This question has been asked before in this thread, but still I am eager to hear from more people about how Q701s would perform with the Sound Blaster Z series sound card. This sound card has a dedicated headphones amp (Maxim MAX97220) which is supposed to drive cans up to 600 ohm. I know driving headphones is not only about resistance but the issues of sensitivity also come into the picture, but I don't have much idea about how the headphones amp on the Z would react to less efficient headphones. Would the Z drive these cans to acceptable levels?

Also I read that some people complain that K/Q 70x series do not provide accurate timbre. Any musicians to comment on that?

I don´t know about that card specifically. Driving a headphone properly relates more with the power that the card can provide. I mean, If it provides high voltage, but doesn´t have power, 600ohms cans will sound very loud, but difficult to drive cans will not sound at its best because you are not providing enough current.

 

In my experience with these cans, when they are not properly driven they lose a lot of detail. As a lot of people already mention, that doesn´t mean it will sound bad, it will just not be that "sharp" and precise, and therefore you will lose timbre as well as bass (yes, even more bass). Actually some people prefer them coming out from an E17 or an E07K because of this fact, even E5/6 in some cases. They tend to sound smoother.

 

In fact, I really love them for vocals. I cannot recommend these headphones enough, and the prove is that I own two myself, but I think an external amp would be recommended. The CMOY is a really cheap option.

These were such a great headphone.  I remember I put them out and didn't realize they were SO power hungry.  Once you get the right amp setup on them, they are excellent.  There was only one other set that I got out during my retail career that were better than these...and it wasn't by much.

After a month (maybe longer), I found an eBay listing for four of these. My amp only uses one at a time, so... Should be good for awhile.

Girgle

 

I talked to the guys at Schiit regarding their, uh, "aloof" description of the Valhalla's strengths and weaknesses on the site.  They specifically told me that while some people "like" the sound of the Valhalla with the Q701, (as I'm sure I would), that it really can't power them well, is not designed for them, won't get you a lot of volume, and isn't really the best choice.  Again, they suggested the Lyr as the far better choice.

 

I don't think this is at all a "we want more money" situation, but simply a "we want you to be really satisfied with our stuff, so buy what is properly designed for them" situation.  And having used a lot of underwhelming amps with the AKG in the past, I would certainly have to agree.  It's worth doing the research and ponying up a few more dollars when possible to get what is designed and what will work well with your headphones.  IMO of course.

 

Elwappo

 

To better answer your question, I think it'd help to hear in your own words what you like in the M-Stage, and what more you might be searching for.  What I loved about the M-Stage was that it handled my K (not Q) effortlessly, and drove them well.  It also sounded great, and fairly warm for a SS amp, again with my K702.  I have not heard it with my Q yet.  However, when comparing it to other amps, I could clearly hear a loss of detail, sustain, and sparkle with the M-Stage.  It wasn't so much that it sounded bad; it didn't.  But that I knew the AKG was capable of so much more than the M-Stage was able to provide.  I'd assume it'd be the same situation with the Q701 as well.  That's just an assumption, based on the same driver being in both cans, and others can chime in (or chide me) on that.

 

The Matrix was my tide-me-over amp anyway, while I saved the money for a Glow.  And that is the amp I am extremely happy with, and I've stuck with, after many trials including the Grace 901, O2, some quality vintage gear, several low-end Headroom amps, two Wheatfields (both of which I loved), and many other portables.  I'm sure there are a ton of great amps I missed, but I love the Glow and about the only other amp I'd love to try would be the Woo 6.  I'm into the idea of the Lyr, but everyone has said it's painfully easy to blow your cans and your eardrums with those, so I've passed.  I suffered an ear injury a few years ago, and don't want to repeat that experience ever.  Plus, according to several threads on this site, the Garage Amber sounds comparable (dare I use that word anymore in this thread?) at a much lower price.

 

62ohm

 

Check out the Garage Amber.  I was all set to buy a Lyr immediately, but after a lot of reading I figured the Amber would be worth a try, and it works well with the Q701 and has great customer service, just like Schiit's stuff.  But it's a $130 cheaper.  I have not heard either; but if you're struggling with cash, it may be worth a try.  I personally decided on the Amber, but then got a lucky break and was able to get a Glow again.  I'm currently in a holding pattern waiting for both my Glow (newest model) and Q to arrive.  I live overseas and buy from the US, so it's always an issue getting heavier stuff sent to me.  I may have to just go pick it up in person when I visit.

 

On burn-in, I've only experienced a whopping difference between out-of-box and 100 hours (or so) after use with two headphones: the M50 and the K701/2.  I've heard a lot of people with the Q701 have experienced the same, and of course one person reminded me that he thought they sounded great out of the box.  But, you're not alone if you've experienced a little harshness or other unhappy sounds "just out of the box."

I saw one in the forums with upgraded op-amps, but don't know if it's a good deal or what.

Thanks for the pic.  I've only used audiotubes.com for info at this point, as well.

Though I'd recommend skipping the actual amp unless you're into soldering and modding, I found the Bravo tube amp thread to have a lot of info for people just starting to learn about tubes and stuff.

I think it was ironic that, after buying the tubes over 6 months ago, I only just finally got around to rolling one in the day before you said you were getting yours ^_^

The Amperex tubes I found were listed NOS, but I assume time or some manufacturing defect took their toll on my particular units. Brent actually seems to test a wide variety of tubes, and trying to build a good reputation, so tubes from him may sound a world different. You'll also pay relative to their worth, so... no lucky bargains, LOL!

Tubemaze also seems like they'd be a good option. And then there was a guy who cryo-treats tubes, even if you don't think the treatment is necessary (scientifically it makes sense) the units would be of reliable quality.

At the time I bought the tubes I have now, I was between college and a "real" job, doing little graphic design jobs, so if I REALLY wanted something, I had to bargain hunt. Then I got a stable job, and now I've started something more career-worthy and I'm putting money into savings monthly, which feels great. Now, if I can only find a roommate to keep me from being lonely or going overboard (sometimes I get obsessed with things and spend too much time), I can move out of my mother's house XD

Still nervous to actually compare the Q and K712 head-to-head, except for the obvious things of wearing comfort (only long-term issue that causes discomfort with the K is... my sideburns get scratchy after a while with Earpads resting on them, but that's my own problem biggrin.gif

All this talk about bass mods (yes I've read all of the hundreds of pages!) got me trying some EQ to bump up the bass. I tried a 2db increase at 30Hz. Not much difference, just some extra presence but no more warmth. Then I tried 4db at 30Hz, 2db at 60Hz and 1db at 120Hz. More warmth, more presence ... but I didn't like it! Somehow, it just doesn't seem to sit with the Q701's signature (mine is unmodded BTW).

 

For me, the Q701 has a fairly good combination of bass speed and extension, and it has a stab at weight and impact too if the recording lays it down. For the money, I'd say it's not just fairly good but very good in doing that type of thing. It's not bassy or warm though, for sure. But, if my EQ test was anything to go by, it seems what I would like is not just warmth! (This sort of thing is down to personal taste though.) Even more speed, extension and impact would be great ... but EQ doesn't give me that. I think you need a more expensive headphone for that.

 

I have heard the Abyss headphones, at over £4k they should deliver dream bass speed, extension and impact as well as everything else. They should ... and I can tell you they do! A warm balance doesn't give you that and it never will.

 

I'm pretty happy with the Q701. Some comments here have been "bright" and "harsh" treble. Mine are not bright and they are not harsh with my Benchmark DAC1 HDR (configured specifically, as I referred to in an earlier post). They aren't perfect but bright and harsh don't come into it for me ... it's detailed and civilised. Maybe this is why I'm not desperate for better bass, even though I know it exists. I can and do listen for literally hours with pleasure to all genres.

PS: It might be that the bass mod works better than EQ. I am open-minded about that.

This is the most likely possibility. Physical modifications can affect damping and other properties that software EQ doesn't touch.

I found this to be true. I always gave my Q701 a 2-3db bass boost, and after the mod I am no longer using a bass boost. Doing the mod isn't quite the same thing though. It sounds different than just adding a couple DB with EQ, the bass definitely sounds different. There is definitely more impact, much better sub bass extension, and the bass simply no longer sounds over dampened. In terms of how much extra bass, I'd say it added maybe 2db from about 100hz and below, and maybe an extra 2-3db from 50hz and below on top of that. The bass is definitely more linear now. I don't sense any extra warmth, it's mostly just better low end bass. 

 

I will agree with the others that said that this mod also makes the Q701 sound even more open and added a touch of depth to the soundstage as well, and if possible makes them sound even more clear and detailed. I honestly still after a few weeks have no regrets of doing this mod and still haven't noticed any negative side effects.

Yeah, no "lucky bargains" there, but assuming he's honest (rep herein seems solid) and his testing methodology is good, the $69 Bugle Boys might be worth a shot.  Well, I need an amp first!  Seems it won't be here until Friday or Monday.  Good thing I'm a patient man.

 

I got my Reflector 6N23P-EV Military Cryo from the Cryoset guy.  Upscale Audio will also cryo-treat their tubes on request.  That site is nice, as they will state plainly that certain tubes they have simply aren't up to snuff for pre-amps, and thus only rate Drive Grade.  I figure later, like at least a year, if I'm unsatisfied or itching to try something new, then I'll go bargain hunting.  With three pairs to play with, I'm definitely going to be patient.

 

Ah, I remember those daze ;-)  All my erstwhile roommates were usually trying to coax me into bad behavior, so caveat emptor.  I'm not sure it improved once we all had decent jobs.  Down to a club for a concert, then off to our local watering hole.  But hey!  Don't knock your hobb[y | ies]!  ;)
