UE Pro Reference Remastered (UERR/UERM v2)

It's an active buffer that outputs near zero OI. Unfortunately that's all the published info.

If anybody in SoCal knows this guy you should ask him how it works...

Anyhow, to my ears, using the line drive with UERM+iPhone removes the OI/amp FR issues in the treble. This audibly improves coherence and clarity while also reducing potential fatigue issues. It also really shows you the limitations of the iPhone DAC in terms of tonality and staging etc.... So three steps forward, 1 back. Still a solid net gain.

 

I think marv should use sbaf funds to get a uerr custom and settle this for good

 

What about measuring a custom UERR? No need to waste a thousand dollars for something he doesn't like and would have to sell at a big loss.
He could also measure different UERM customs to compare. I've wanted to get my UERM measured by the Messiah for a long time, because I hear a peak around 9kHz that his measurements don't show.

EDIT: I also think the universal UERR measurements are telling and in line with what people have heard. I don't think there is an issue that needs solving.

 

It seems like a waste of money to pursue UERR any further. Perhaps it would be good for mastering but musically it's like a limp UERM that has potential but ultimately little/no engagement.

@shotgunshane seems to think Perfect Seal Deca is a more worthy successor. The launch discount makes it $1050 and a universal is available...

 

I would like to ask guys of SBAF, can you recommend any reasonable cable for UERR/UM, that comes without that annoying memory part? Thanks

 

Re measurements: I am bringing both my UERM and UERR to the SBAF meet in November. If there is a measurement rig there I would love to get both measured. It would be perfect for direct comparison since both are made from the same impression.

I prefer the UERR for regular listening as I like a slightly dark presentation. I prefer the UERM for mastering and music "work" though it's also fantastic for listening if the material is good. UERR is also fine for mastering but for the type of stuff I do (remastering old latin music where the issues are usually super hard mids or way too hot treble) the UERM is a better tool.

 

I would recommend just cutting the plastic sheath off and snipping the memory wire entirely if you really want it gone. Of course, be VERY careful not to cut the leads. Replacement cable is only $40, and I doubt you will find anything made to that level of quality for the same price.

 

I have just received my UE Pro Line Drive and it has really brought the UERR into life.

Was previously driving the UERR with my iPhone and I felt that while the UERR has a more pleasing sound signature, the dynamics is relatively poor and the soundstage is congested. Also, the top end is rolled off quite significantly.

However, the UE Pro Line Drive corrected all those phenomenon and I'm really enjoying the UERR now.

I'm letting it run in and have yet to listen to it with the UERM to see whether it will bring any improvement.

Will report in again.

 

+1 on pro line drive pairing awesome with UERR/UERM. The UE IEMs really want that 0 output impedance to sound best.

I've had my line drive for a month or so now... absolutely recommended for use with any source/amp that doesn't do near 0 OI.

 

With the UERM a slightly higher OI may not be a bad thing depending on your preferences for brightness. I've thought about replacing the stock cable because it seems to have a slightly high resistance, but then again I like the tonality the way it is right now from sources with an OI between 0.5 and 2 Ohm.

 

Late to the party --- just read thru the last eight pages. LOL...

So much to say, so little time... with the little time that I do have, I do want to mention that people I've talked to from GRAS and Knowles have mentioned that 711 couplers are effed up in the upper treble >10k. That's why there's the new GRAS 43BB with a smoother resonance response between 12-15k (it's an ear simulator and microphone system that works in concert). There's a great, great presentation from a Jacob Soendergaard from GRAS (he's now at HEAD, according to his LinkedIn) that he made at RMAF last year. It should be on YouTube somewhere (the moderator might make you loath to watch it, but really, it's a great, great presentation and anyone would feel a little more like Gunnar Rasmussen after watching it)

I too like the UERR (only heard the universal demo, stuffed as deeply as possible, with Line Drive attached) a lot, but like what most others have mentioned, it is quite laid-back and has more bass than I'd consider neutral. The main culprit to me is 800 - 3500 Hz. It doesn't rise properly above the bass. In my experience, with all phase being approximately equal, IEMs with laid-back 800-2700 have an "open" center image, giving the illusion of a larger soundstage and breathy vocals because the relative difference between the lower midrange and upper has been nullified, but depth and layering takes a hit.

Still considering a pair, actually, despite its shortcomings. I love the elegance of the acoustic pathway.

 

I've looked in the loaner forum and didn't see that a UERR loaner ever went out. Does SBAF still have a universal UERR around? I'd love an opportunity to hear it. I'm no where near any UE dealer to hear one. Thanks!!

 

Anyone know how to get a "meet discount" on these without waiting till NY CanJam next year?

 

I know I'm way too late to the party, but I decided to give the UERR and UE LIVE a listen today and compare them to my UERM on both my GO2A and Moondrop DAWN.

UE LIVE

• Not as warm and bassy as I expected, but definitely warm and bassy
• Soundstage is big, but not nearly as large as UERM
• Leaves out details, also due to its tuning
• Very even and soft tuning, not annoying at all
• In terms of resolution just slightly behind UERR
• The upper bass is a bit weird from having both a dynamic and ba driver

UERR

• Sadly it sounds a lot warmer than even my modded UERM
• Stage is smaller, but more precise than UE LIVE
• Midrange is too nice sounding, lacks bite
• Lacks dynamics, is also way less sensitive
• Sounds compressed in general
• Lower treble is still not as smooth as it could be
• Just sounds jumbled or confused with a lot going on, not as resolving
• Bass isn't slower, but it's less impactful and less realistic sounding

People said the UERR was just tuned warmer and is generally as resolving as the UERM.
I call bs, it sounds jumbled/confused with a lot going on
Stage is smaller which I'm not sure is purely from being a universal demo

It's also like 10-20dB less efficient... Like where does the power go?
Is it all wasted in the crossover to get the tiny supertweeter integrated?

At least extension seemed good. I could hear 18.5k instead of 16.5k on my UERMs.
