Seems to me the dac end of the MX2 using the PCM1796 is a newer version of the PCM1794 which is a nice standard DAC chip. . It has a very nice clean sound to it much like the CS4398 chips  I can confirm the DAC in my ME is superior out of all my units. But it is more the OPA2227 and OPA2134 used in the amp portion that acts kinda like the LT1028 does for my FP.. The sound combo is very nicely done.. These guys clearly know their sound using this combo..

 

If your looking for a nice high end portable DAC. to use with your amp. Look into the HRT microstreamer. Seems to be just as good or better than the ME but cost $100 less.

 

Thanks for giving me your impressions. I am really quite satisfied with the FP's DAC for now. So for the time being I will enjoy my FP until something else comes alone that is significantly better for a bargain price. And I am sure I will read about here on Discovery first! :)

Don't know if you tried throwing a new op amp in your FP but if you see a dual OPA LT1028. on ebay. They cost around $16 shipped but throws the FP into a complete different category in sound. I think my MX2 is overall superior in sound to the FP but I will not get rid of my FP for nothing. It blew my mind just how good that unit sounded when I changed out the Op amps.. Those dual Opa LT1028 sold out really quick online for a reason but there is a dual op amp adapter you can buy and 2 separate LT1028 chips that will yield the same sound.

 

You won't need to hook it up with any other amp once you try this.. For the increase in fidelity I think it is worth doing for certain as you know the stock opa on there is just average at best.

Build Quality

Build quality is very good. housings seem solid and are made from aluminium and ABS plastic (which is supposed to refine the sound). housings have pretty good and flexible strain reliefs, but they could be a little longer and more flexible. They are adequate imho and should be able to withstand daily abuse with ease - design of the reliefs is pretty good and they don't create any "hot spots" in the wire, in other words - they work as they should :) also, they are finished beautifully and just scream classy :) that's a definite plus to me.

cable itself is pretty thick, flexible rubbery cord with some grooves along the length. I don't really remember what these grooves are supposed to do, but I'm pretty sure they either lower microphonics, or prevent tangling. Truthfully, tangling is almost non-existent, but microphonics are sometimes annoying. they can be lowered by using the cable cinch, but it doesn't solve the problem entirely :( It's not that bad, but still, it exists. good thing about the cable is that it is same thickness from the jack, to the housings, and inspire confidence. jack is really small, plastic, but has good strain relief and is L shaped, which I prefer to straight or 45 degree ones. 

All in all, I'd say build quality is really good.

 

Comfort

although the drivers are one of the largest dynamic types used in iems (16mm) the design is really good and enables them to be really comfortable and don't cause any kind of fatigue in the ears even after long sessions of listening (I've had them in ears for 4-5 hours straight, without any issues with comfort whatsoever. stock, tips, while do not sound that good, are definitely comfortable.

 

Sound

Bass - members here named these iems the bass kings and I have to agree. bass is the foundation for the sound here, but it is not the regular kind of bass. there is no mid-bass hump, only the sub-bass is accentuated. the result of such tuning is that the bass never bleeds into the mids, and isn't bloated or offensive. I'm no basshead, but these sound pretty good to me. almost every other iem I've had, (except for meelec m21) had quite a big mid-bass hump and I always eq-ed it down. I don't have to do the same here. bass is controlled, and quite tight. it can become rumbly, but only when the recording calls for it. extension is the best I've heard so far, and can actually feel it vibrate to 15 hz or so, but at about 20 hz it is there sonically. As I've already said, the bass is big, but very controlled. it really feels like a subwoofer at times :) I would suggest this iem to non-bassheads because while they are really bassy, they aren't offensive in any way. 

 

Mids - these Iems are bass iems, but I actually love them because of their mids first, then bass :) mids are smooth and quite detailed. they reproduce strings, piano and vocals really good. mid section is pretty flat, but there is a slight bump at around 6-6.5khz area. I would say that it is maybe 2-2.5 dbs, not more. One can always eq it out, and unlike many other iems, sound can be tweaked without much hassle on these. I just left it as is - it's not that noticeable or in any ways offensive. these will never get shouty or sibilant, so no problems there. nothing sounds unnatural, metalic, plastic or anything - timbre is really good and natural, well suited to acoustic music. I'm bad with all the terminology and describing the sound, but I'd say the mids are not thick, nor thin, quite detailed and transparent (if I can even use this word describing the mids). but this I can say for sure - the best and most enjoyable mids I've heard from anything, not only iems or headphones :)

 

Highs - highs to my ears are pretty sparkly, but there could be more sparkle I guess... they extend pretty good and then roll off. highs are detailed and never sibilant. this is a definite plus, because the thing I hate the most is sibilance. whole sound can be ruined for me just by that. not an expert on highs, so I can't add anything more. all I can say is that highs are more than enough for me and adequately detailed. they say that JVC FXD series are better in this regard, but I haven't heard them, so...

 

Sound stage, presentation

sound stage is big. I would say too big for some recordings :) just try and listen to Dr. Cheskys new album, the drum and flute piece, and You'll understand what I'm talking about - it feels like I'm listening to the single drum and flute from far away. it could be described this way - imagine you are sitting in the middle section of a stadium and the flute and drum are positioned in the opposite ends of the field. they sound distant in this piece. Don't get me wrong - it really depends on the recording, because these can get really intimate and bring some instruments up close, but they can also send them to rare plains, far, far away :D this works great with  classical orchestra music, jazz and everything, except for weird recordings like the one I mentioned above :) instrument separation and detailing is really good, and the wide and high Sound stage helps with it even more - sometimes I feel like I'm sitting in a concert hall while listening to dvoraks 9-th symphony, or I'm in the same room and sitting in the front rows on Art Blakey and the jazz messengers' jazz session. Instrument positioning is good, but still it depends on the recording. The drivers feel fast, fastest I've heard. busy rock passages are well reproduced and you can tell every string from each other.  

 

overall, these are bass iems, but I actually prefer listening to non-bassy music with these. This is mainly due to its relaxed and laid back, immersive presentation and excellent mids, but also for the simple fact that majority of hip-hop recordings is of low quality and the bass sometimes is bloated. but good quality hip-hop sounds excellent! (nujabes, DJ Okawari, Tsuchie, Tech N9ne). great bass extension also helps with some classical pieces, like the Bach toccata and fugue, that really needs good bass extension for the organs, is really enjoyable with sonys.

 

I would say that these are quite good and at about 90-100$ are a good buy. I enjoy the hell out of them even now, as I'm typing :)

 

oh, btw, listen to this excellent piece with your XB90EX:

 

you can thank me later :)

 

edit:

 

I just discovered that youtube is an *******. I uploaded this yesterday, and it sounded almost as good as it sounded in the source flac, but just now I've listened to it again and it sounds like **** :( could they process it more after uploading to reduce the size even more? 

 

Great review, I'm thinking of buying these as I'm disappointed with the Bass on the XBA4, would you recommend these? in terms of sound quality do you think it'll be a big downgrade from the xba 4?


Cheers.

Thanks for the suggestion, but I like my Little Dot way too much to go back to an SS amp... But thanks again! :)

first of all, I don't own the xba4, so I can't give you a definite answer, but my guess would be that xb90ex won't be a big downgrade from those. maybe some detail will be lost and instruments won't be that well separated, but I think you will like these for what they are - relaxed, smooth sound with lots of presence and energy where needed, big soundstage and presentation, excellent timbre and realism of acoustic instruments and vocals. base is big but it doesn't muddy up the sound and stays away from the mids. if it sounds overwhelming to you, you can always equalize it to your preference...

 

I highly recommend them, after owning these for a while now, they didn't become boring (as many others do) to my ears...

Hi, Thanks for your reply, I currently have the XB41's and the bass on those is really good so I have high hopes for the XB90's. Real Shame the XBA 4's aren't what I thought they would be, considering it has a woofer and a super woofer.

armature's aren't as capable as dynamics when it comes to reproducing large amounts of bass, so even if it had one more superwoofer, it would never comeclose to xb90ex in terms of bass quantity...

Ah right, I wasn't aware that was the case. Other than the Bass they are excellent, I kept them on for a while and thought na i'll sacrifice the bass since the sound quality is a lot better, went back to my XB41's and thought damn, the bass is just so much better I'm happy to lose some of the clarity for it.

all I can say that you'll be even happier with the xb90ex :D

Maybe you can try to argue with them that a $36 fee for an $70 iem is just too outrages and see if they will let you off with paying less or might give you one time exception. It doesn't hurt to ask, and try to argue your case, but just be nice and firm about it.

 

What happens if you refuse pick up/ delivery and tell them to send it back to the seller, will there be fees involved??? If this is the case it's good to inform the seller of the situation as well. But it's up to you Gee and i have not idea how they do things in Scotland so................... take my advice with a grain of salt.

 

Yeah I thought the price was a bit much myself but as the letter states, they don't do disputes over pricing etc so I didn't bother arguing my case. I just tested them now before burn in and wow these things sound great. I'm not an expert and can't really describe in that much detail what I'm hearing but I'll try.

 

When I first put these in my ears I got butterflies in my stomach when the music started playing lol biggrin.gif Everything sounds so clear! Lol, the detail is awesome. Mids on these things are amazing, they are smooth and sweet, very detailed. Highs are nice and sparkly and extend very well, they don't really offend me, I'm not experiencing much sibilance either. I was worried that the bass would be lacking but no, it's definitely there! It reaches all the way down but is only there when called for. When you play a bass emphasized song, it really shines.

 

Separation of the frequencies is amazing, each frequency can easily be heard in the mix but it's all balanced, none of them interfere with each other. I would imagine this is similar to what a 3 driver dynamic would sound like! It actually sounds as if each frequency has its own driver lol. Instrument separation is amazing and soundstage is pretty good too. I have to say the best thing about these are the vocals, wow the vocals are awesome sauce! You can really hear the emotion in the artists voice! Overall, these produce such an energetic sound and they are very exciting, everything is in your face but not offensive in any way smile.gif

 

Anyway, as I said before I bought these, as long as they were on a par with the JVC S500's in the bass quantity department and had a better sound overall, I would be happy. Well I'm pleased to report that the bass for me is actually better in quantity and quality than the S500 when the music calls for it. I also reckon these do have the superior overall sound to my ears too so yeah you can consider me pleased with my purchase, the price was worth it in the end despite the shocking customs fee smile.gif

 

Let burn in commence!

^ So glad to hear you're diggin' them Gee. This calls for a gif of major celebration which suits you. GEE GEE GEE babie babie!!! Oldie but a goodie. biggrin.gif

 

post #8142 of 25871

Man, I LOVE the sound on my CKN70s but the J cord..If they had a Y-Cord I'd stop my search for IEMs pretty much. Is there anywhere in Europe/UK I could get them recabled?
