wow - never have issues with background noise with my 901, even with low-impedance headphones/iems. never knew that to be an issue.

In total agreement with the 3K3s. With the RWAK 240 they really sing. Will try pairing the 240 with the Tralucent Ref. 1 tomorrow when meeting up with spkrs01.

It gets about 60% good after 15 000 hours of burn in. You can accelerate the process by putting the 240 in the microwave, but it will only work in balanced mode.

I am struggling whether to buy 240 but my 901 never gave me background noise. Guess I am old and couldn't tell then...

Following up on what my-200 and Fafner have mentioned several posts back.

I'm very impressed with the IE800 and AK240 pairing as well. I have the ALO modified balanced IE800 IEM. Running in balanced mode for two months now, and I have never looked back. The soundstage width and depth, separation and clarity are so well maintained. I have an eclectic taste for music, so I had many opportunities to listen to a wide range of genres. All spectacularly reproduced. I mean, it’s as if I'm hearing the music for the first time, picking out elements, I never realized were present. Subtle musical elements hold their space without louder elements overtaking and bleeding into their space. The only con I have for the IE800, is they do not travel well when you’re on the move. The cable is heavy and noticeably tugs on the IEM's. Microphonics is present as well. So if you’re just sitting around, these are quite nice. Nothing else I have listened to comes close IMO.

 

I have also had a chance to listen with my Heir 8.A's in unbalanced mode. Great isolation, but this should be expected with a CIEM. I was not so impressed with the low end of the spectrum - too muddy. The spatial representation is compressed and instrument separation is just OK. However, the 8.A's do travel well. Don't have to worry about adjusting or re-adjusting your IEM's while you move here.

 

Next week I'll be receiving a balanced Silver IEM cable from DHC. I'm really interested in seeing if there will be any improvement from my 8.A's in balanced mode.

 

I also have HE-500's and quite frankly, these require more power to drive the AK240 effectively. The HE-500's sound OK, but as most demanding headphones go, additional amping for this portable rig is needed. The headphones will remain with my desktop setup.

 

May be tempted to pull the trigger on either the Roxannes or the Kaiser 10's. Has anyone paired the AK240 with either of these? If so, what's your opinion on how they sound?

You might also want to check out Tralucent 1plus2, or the new Reference 1 IEM's. Both sound superb with the AK240.

IE800's classical is unbeatable, instrument in general is better than other IEMs (very general that is since there are so many different instruments), male voice is oh-very-nice. People mostly complain about its female voice but to me it doesn't sound all that bad comparing to other IEMs I've heard. Oh and, its price is also unbeatable comparing to other brands' flagship IEMs.

If you have something against dynamic IEM or IE800's sound signature, I suppose ToGo 334 is a good one too. My impression of it is a BA IEM trying to sound like dynamic. Personally I wasn't impressed by it though, but I haven't tried it with balanced cable.

 

I very much appreciate the reply. I have a pair of IE800's on audition. They barely have any hours on them but I find the low end somewhat muddy on acoustic bass.  They do sound nice on classical so maybe they just need to break in.  What is the difference (sonically) between the unbalanced and balanced and where does one purchase a balanced pair? I just ordered the ones I have from Amazon.

 

Thanks again!

Was my question that silly to you?

ALO audio sells IE800 with the balanced mod.

Not at all that was a harmless joke, most of my friends seem to agree that it benefits from burn in. However I have to admit I am skeptical on giving a number of hours and percentage of the ultimate sound...

Sure. Please refer to here for unbalanced IE800 vs balanced. daseinpdx has posted the ALO link above already for where to purchase. To our knowledge (correct me if I'm wrong) ALO is the only one modding IE800 into balanced so far.

For those of you that currently own the AK240, how many hours of battery life do you get when playing standard 44.1 flac files? 

post #1109 of 2222

About 6.5 hours.

I am consistently getting 7+ hours.
