Greetings to all Head-Fiers, everyone please post opinions,advice,photos,etc.... As i am still in dilemma right now to choose  between this 3 portable amps to pair with my JH16 Pro and i still have around 1 month time only to consider to upgrade my JH16 order with JH Audio to the JH3A combo.  ...

Hi there.   I've been steadily upgrading my portable setup since I started here, and I've recently come to a very happy point where everything is sounding really good.   Right now I'm running a Whiplash Audio modded iPod classic (5.5, with the Wolfson chip), using a Whiplash TWAg LOD...

Hey Guys, in the market for a portable headphone amp. In my limited research, I have found that the RSA predator and Practical Devices XM6 are popular and have had many good reviews, but haven't really found anything putting these 2 amps head to head. Can anyone recommend one over the other? or...

Bought one to use with usb out of my iPad camera connection kit. When I tried it the Ipad's usb bus couldn't power the dac. I knew this might happen but I wasn't too worried as PD offers a 30 day money back guarantee. Only problem is they have so far ( about 2 weeks) been unwilling to give me an...

Any thoughts or opinions on which of these two choices ?   Thank you

I love my XM6 with the OPA134 and buffers in it but I was interested in upgrading the op-amp to the best I can get and came across this thread (http://tangentsoft.net/audio/opamps.html) where the guy compares all sorts of op-amps and is pretty convinced OPA627 is the top gun. Price is not a...

Evening.   I'm a couple of hours away from splurging on an AK100 and I wanted to ask for opinions on the options I have. I'd be lying if I didn't admit that the AK100+Continental V3 is pretty alluring to me. However if I, just for a minute, ignored the cost of the V3, I couldn't ignore the...

Ok, here is my question. I am looking to get a portable amp/DAC . I want an amp the will allow me to tweak the BASS and that has cross fade. I like the XM6 because I can roll the chips. However, I like the thin size for the arrow.    My current headphones are V-Moda LP, Shure 215 Limited...

Posted this in the wrong thread by accident so I am copying it here where it belongs...     I am in need of an XM6 expansion connector to RCA line out adapter.  Does anyone make these?  I have emailed Practical Devices about it but got no response.  I don't really feel like hunting down...

I'm looking foward to buy a new DAC/AMP combo for my Galaxy S3, and make sure it´s better than Titanium HD DAC and integrated headphone AMP. I have a budget of ~300; I was thinking in going for this uha-6s-mkii/ but no have idea of others alternatives. I Mainly will be using Grados 325 for...

I’ve been reading through a lot of posts here and have learned a lot. I’m hoping y’all don’t mind if I ask a few newbie questions to see if I’m on the right track.   I’m using mostly my iPhone 4s (but sometimes my iMac) to listen to AAC files recorded at 128 bit rate, but also have a few...

Hi all,    What player is good for ER4P and XM6 !?  is DX50 suitable for my exisitng equipments? thanks

I know this is covered in other threads, but it is so buried that I'm going to make a thread dedicated to it Anyway, so you just bought a Nexus 7, congratulations, you actually got a device that will make your ears happy.  There is one caveat though, you do need to do a bit of work to get it...

Hi,   I couldn't find such a list anywhere so I wanted to create a resource for people to post android devices that can run USB DAC. So far, I was able to get Nexus 7 tablet to run my Practical Devices XM6, and a cheap-o USB audio plug-and-play device. To do this, I had to:   Buy an OTG...

Not sure if its the right section sorry in advance if not :) Hi all, All this adventure started with buying headphone for my iPhone and Will finally cost me an arm and a leg. My girlfriend dont like that i burn So much money For my sole person.... So my portable/desktop hybrid rig Need to...

Due to discussion over at the Fiio x3 thread many users seem to be calling for a transport system whereby implementing the use of the users own DAC and AMP sections configured by themselves.  So i would like to start a discussion based on idea's/solutions/demand for such a product.  What would...

hi Guys, I just recently started to use my headphones more freqently while listening to music and now that I am about to get the Beyerdynamic dt-770 pro (32Ohm) I thought about getting myself a DAC/Amp combination that wouldn´t hurt my wallet to much. I also am thinking about getting the Grado...

My new XM6 just arrived and it sounds awesome both through USB from my macbook and from my ipod headphone out.  I have a few questions however:   1. What is a good Dock to Line Out adapter to use for my ipod to get even better sound and does using line out make it sound that much better? The...

I made another thread for dubstep music type headphones and got some good feedback.  Now I also plan to buy some expensive headphones and a laptop for listening to music and movies.   I want the movies to be imax quality sound.  I know it cant be that good but I want it to feel as close as...

Trying to simplify my setup now.  Want a portable Amp/Dac for traveling with my laptop and then when I am at home, just output it to a desktop amp via RCA for bigger headphones.  Only two I know is the U-Dac2 and Ibasso D7.  D7 has a quality DAC chip, but I heard it is flaky with driver issue...

Hi guys   My current set up is an iPod Touch 3G -> Predator -> Jh16 I just got a pay raise, and coupled with my accumulated savings, i was wondering if i should start looking around and trying out something new. I love my jh16's and predator to bits, but have become very very intrigued by...

Yes, this counts as mini for me.  I’m prone to rambling...   Since Lord Voldemort was kind enough to send me one of his Objective2 prototypes in return for being one of his loyal minions (or maybe just giving him some useful advice from a different perspective) I figured I should write up...

I like many of the features of the E17 amp -- digital control, and EQ for bass and treble. The reason why I like the EQ should be obvious -- more control over the sound of my music. I like the digital control because it makes it harder to accidentally turn the volume way up while the thing is in...

I have decided on the Beyerdynamic  DT1350 and i have the iPod Classic latest gen. 160 gb, but i need a amp/dac and as a noob here i cant really decide on which i want to get. size (relative) and weight is not really a problem.   I have eyed a few brands and models and here they come:  ...
