Shure SE846 Impressions Thread - Page 692

post #10366 of 17052

The problem with the impedance ratio when it comes to iems, as I see it, is that most (all?) iems have much lower impedance than do full headphones.  So you are never (or almost never) going to get that sweet spot ratio of 8:1 or 10:1 (depending on who's talking).  This includes iems like the Roxanne and the 846, but also the Altone200 and the FidueA83.   So, if you can't get the ratio, you are left with knowing that any iem you get will be, on paper, "wrong."  

 

At that point it comes down to sound.  I'd suggest throwing out the paper and going by other users' comments.  Since the AK series has an impedance somewhat close to the Pono, and both sound good with the 846, listen to the owners.  While an X3 is (from what I'm told) good, I don't think it compares to an AK anything or a Pono.  Getting it solely because of a ratio seems counter-intuitive.  The great thing about this site is that you can ask others what they use.  Look at the sigs on this thread and see what folks pair up with their 846s.  Or simply ask.  I can tell you that the 846 sounds good with the X5, and it sounds better (to me) with the Pono.  It sounds even better still with a balanced cable with the Pono.  Lots of folks here use AK and DX90s, see what they say.  Cayin has a nice new DAP that's getting good reviews.  That can be a good starting point.

I never heard other DAPs before. So I can't compare with other Daps. I only know that AK120II which I owned with a balanced ouput 1 OHM is a perfect match with SE846 which has a 9 ohm impedance I can turn to 24 increments out of 75 and have sufficient volume for indoor listening to 24/96 pops, this is also the case with AK240. When I start  with 2 ohm output impedance of headphone singled ended to SE846,  the sound is thin and treble is not so smooth and bass is not enough, volume need to turn up to 28 increments.

On my Pono I find that 25% volume gives me good sound for most songs, some need slightly more (maybe 30-33%), the only time I get even close to 50% volume is for DSDs that seem to all be mastered/mixed "low."  On my X5 I need the volume up a bit more across the board.  

post #10369 of 17052

My DSDs which are all pops downloaded has the same volume output of other 24/96.

post #10370 of 17052

Mine are from SACDs and most definitely play at a lower volume than my other files.  I have to be careful after playing one to turn down the volume before playing a "regular" file. This is in a Pono with balanced cable- and the Pono is playing the DSD as a DSD, not down sampled.  

post #10371 of 17052

I'm using the 846's with a Cowon P1, which claims an output impedence of 3 ohms - they sound quite balanced to me, and are not shelved up or down, either to or bottom.  Treble is clean and dynamic, instruments have air around them, and bass pitches are easy to hear - I think they call that 'tunefull bass'.

 

I very much like the combo.....

It reminds me that my AK120II needs to convert DSD to PCM and not natively. This may be the difference with yours.

That is not true as the most important aspect is the impedance response. If it is flat (let's say IE 800) it is not important for the frequency response to be connected to a low impedance source (but distortion my increase). When the SE846 gets connected to a higher impedance source there will be a raise in bass and upper treble because the frequency response the player puts out isn't flat anymore and will look more and more like the IEM's impedance graph the higher the output impedance is.

In terms of frequency response a close to 0 Ohms output has got the more linear output with an IEM with varying impedance.

The changes in frequency response may neither be noticable nor disturbing to some people but they are there and you can measure them.

post #10374 of 17052

Yep, I already re-posted (thanks to the original poster) a review with a chart showing various iems and how they respond.  If I recall correctly the 846 had a treble dip and the Roxanne had a treble rise when connected to a Pono.  

 

But, again, unless the effect of an impedance mismatch is disturbing, for me it really doesn't matter.  All of these devices and iems and headphones are different, and all of them have different synergies, and all of them come down to a matter of personal taste.  For my taste I like the combination of Pono and 846.  I might not like an AK120 and a Roxanne, or a Cowan and a Fidue A83.  That's what makes this hobby so interesting- putting these things together and hearing what sounds good to each of us, personally.  Science should never drive art.  And music is art as well as science.

@olddude: :beerchug:

 

By the way, that's the impedance response of the 846 (credits go to innerfidelity):

 

and the frequency response being put out by the AK240 (unbalanced) with the SE846 being attached (credits go to Bad_Robot at hifi-forum.de):

Bass raise, mid treble dip and gentle upper treble rise.

Quick poll: what filters are people using? Usually people here tend not to be fans of treble-heavy sound so I would guess balanced and warm are the most popular ones. I finally got around to trying out the filters and while I still prefer the default one, the bright filter is actually surprisingly nice too. It really depends on the recording. It doesn´t do well with top 40 treble-to-the-max pop music, but it works great with vocals/jazz/etc. The warm filter seems to be a bit too rolled off in the treble, I get a constant feel to raise the volume to dangerous levels.

 

Now I´m torn between the bright and balanced filters... There´s one big comfort (or peace of mind to be more precise) related plus for the bright one: you don´t have to worry about the foam inside the filter getting ear wax in it. I use the silicon tips so there´s no filter in the the actual tips, thus it´s just a matter of time until the filters that include acoustic foam get too dirty and ideally would need to be replaced. Does anyone know if Shure plans to sell new filters? I´m also interested in modding a filter to be somewhere between the balanced and bright one...

post #10377 of 17052

Take the foam out of the blues and it sounds very good.  Not as good in the trebles as the white, though.  

 

If you take the foam out with a pin, save it, you can put it back in the filter.  

 

Tips matter as well.  They will definitely alter the sound a bit.  So mixing and matching tips, filters, foam and no foam, is the way to go.  Eventually you'll find what you like.

 

I'm using the whites and Comply Pro tips while waiting for my Sensaphonics to come.

What comply tips do these use? TX-100?

That's a typical cable issue with IEMs that use a coaxial connector system. Slightly bending the center pin or squeezing the round part may help. I had the same issue with my SE425 and squeezing the circle thing on the cable helped.
Imo that coaxial systemmprovides better insertion comfort but less durability than the classical 2-pin connectors.

Loving these 846's.
