some R&D info released by ibasso forks.... i guess it is to vs pico.. D2 R&D Report

Okay guys and girls, I've been out of this stuff for a while (been busy with life). I am getting tired of my UE Triple.fis. They sound great, but I want something new that's fun, better bass and easier to put on and take off. I adore the clarity and soundstage of the triple fis, but don't like...

Has anyone had any luck sourcing a replacement battery for the iBasso D2 Viper?   The specs I found cite an "8.4v 470mAh Li-polymer battery".   Upon teardown of the Viper, what I found were two batteries, wired in series, that both pretty clearly say 3.7v each on them.  Other identifiers are...

Hello everyone, I am searching for my first amp/DAC. It's for my grados SR80s, I will upgrade to Alessandro MS2i soon. There is not much information about this ibasso model, but I plan to buy it with Hiflight OPAMP to add some warmth. Or maybe buy the Schiit stack which has very good reputation...

First of all, I love this amp but for a while now i've been having issues with the output.  If the jack is moved a certain way it will cut out a lot of the sound.... it won't cut out a channel entirely but will get significantly quieter or the bass will cut out.  I listen to it while riding my...

So Im searching for a portable headphone amp within the $100ish range. Ive narrowed it down to the three stated above. I know the iBassoD2+ is a bit more however since its so well liked on these forums I figure the extra money may be worth it. The e7 and the D2+ have DACs however I'm not sure if...

Not sure where to go here. This is my girlfriend's setup and she says she wants better sound. The only thing I could think of, other than a sub, is a tube preamp. To go between the DAC output of the D2 and the amp in the AudioEngines.  Would this help with the sound?   Any ideas are appreciated

I just got this amp and have been out of the head-fi scene for a year or so.  I modded the HD555 and ever since I really enjoyed modding and listening to different headphones.  I had the AD700, HD555, RE-ZERO, TL-02, and a cheap Sennheiser model.  The RE-ZERO's had to be my favorite because of...

Arrgh! In just happily throwing my ibasso D2+ into my bag, I seem to have broken the "charge" on/off switch by pushing it into the unit, so will need a replacement.   Now, I've been happily listening for a while and lost track of the "bang for buck" portable amp discussions. I actually don't...

I've got my iBasso D2+ last week, and I'm very happy with the purchase.   Just one question to everyone who owns it: Does it use USB port power when it's connected to a computer regardless of the charge switch position?   I never turned the charge switch to 'on' position, but it's...

    I have this great LOD for my ipod classic and I have no issues with it (http://microshar.org/product_info.php?manufacturers_id=&products_id=125)   But it does not work with the iphone 4s, so I bought a Fiio L9 to try it out.   It plugs in properly, but the bass is cut off and...

Howdy So I can either get a good deal on a dac I know little about due to unpublishable reviews (m stage dac) or just use the d12 which has a nice dac. Also I have a d2 boa kickin around which I will either sell or maybe use as a preamp? How would this do as a preamp? So d12 vs mstage dac And...

i was looking on ibasso's website and was comparing some specs and was kinda confused as to what the differences were between the ibasso d2 -boa and ibasso d2 + boa   specs of ibasso d2 - boa:   Main Features: - Wolfson WM8740 DAC Chip + TI PCM2706 - USB signal input, provides I2S...

I just got an used iBasso D2+ BOA amp and I am wondering if this annoyance i observed on mine is normal for this model amp.   What I am observing is that everytime I turn off the amp I get this loud "noise" that sounds like at time like the "ray gun" sound in the older movies -  a high to...

Hi, fellow head-fiers.   This is my first posting, but I've been reading the forum for many years. :)   I'm currently using Fiio E7 with my Macbook, and it drives my Sennheiser HD595 or Beyerdynamic DT770 (250ohm). If I get iBasso D2+ Boa, would it be an upgrade?   I don't actually...

Looking for a dac/amp combo. I've seen ranting and raving aboit fiio products, but I've seen the same about most everything on here. I doubt ill he problems with it driving my 'phones them beng gradp sr80i, shrue srh440, and fischer audio dba-02 mk1. That being said, if there's something I...

I only know a couple of them E7 which I have and im thinking of selling it to get a better one UHA-4 Pico Slim Headstage arrow any other dac/amp that are portable, where I can use it with my ipod touch and 1964 T.??

Hey,   I am looking for a portable combined headphone amp and usb dac, is there anything that betters the E17 without going crazy money? Can get the E17 for about £85 brand new now.   Was considering a Xonar STX but it would then restrict me to one source, where as i can use the E17 as a...

I've been umming and aahing over a new amp for a while now, and asked some questions before. My ibasso D2+ has been chugging along OK, so I've been postponing a decision. But last week the left channel started going after 30mins or so use. I've checked cables etc, and it's def the amp.   I...

Hi All, I've owned a iBasso D2 viper (with replaced opamp chip) for quite some time now. Since using it when connected to my Mac via USB it slowly developed a loud cracking/scratching sound when I change volume. It also continues to crackle lightly in the background. If i very gently adjust the...

The D10 is out! With optical in, Coax in, amp only, dac only or both, a run time of 20 to 30 hours and this time, gain control, it will offer many features on the fly. Sockets, so you can roll opamps and a kit with opamps will come with it. There are a few sensitive chips so always ground...

Hi friends, I have recently purchased an iphone and have gotten a pair of headphones with it. But I didn't like the sound quality of headphones. So i want to get a new pair of headphones. Sound quality should be awesome, light weight, needs to be attractive and stylish, heavy bass required...

Ok, here is something i though would be a no-brainer...Which it almost is,, but now i thought it would be...David vs. Goliath:  Goliath is represented by the following setup: Optical input to a Cambridge DacMagic Desktop dac, which then feeds 24bit/192 into a Argon HA2 tube/ss hybrid. David...

Hello, i currently own the ibasso d2 viper and thought my Denon D7000 sounded amazing through them compared to Fiio E5 and no-amp (my only experiences).  However, my D2's need to be fixed so I'm starting to look in to a new amp.  It doesnt' matter if its portable or fullsize, but I'd just like...

I know that "worth" is subjective to each person. I'm willing to spend 170 bucks on a good headphone amp. From what I can tell this is an excellent unit for the money... I am very new to this and am not intimately familiar with other brands/units available. I'm looking to spend ~150 dollars on...
