Hi, I got my O2 a few days ago, and it was working fine for the first day. On the second day i turned it on, used it for around an hour, and it cut off my audio and starting making popping sounds. I couldnt get the audio to come out so i plugged the adapter and it started working again...

I have a Titanium HD sound card in my computer and every time I want to change headphones I have to plug them directly into the sound card at the back of the computer which is a pain.  I was wondering if a stereo extension(something like this) would affect the quality of the sound?  Also I am...

Hi all. After looking around for a while, I've decided to go with HD 598s for my first high-end headphones. I can't decide what to use to power them though. I will be using my desktop for all listening with these, so I figures a sound card would be best. The Asus Xonar STX in particular. The...

Well I re purchased the HD 650 I sold a few months back really missed the sound. I have only used them with my Essence Stx sound card and have enjoyed the combo. But I would like to use them away from my computer so I am hoping to hear some advice on a more portable solution, amp. I read a...

could be my cheap phono cartridges, but using either a Lounge Audio IC preamp or a custom split RIAA eq CCS 6SL7/12AU7 anode follower phono stage with the Indeed doesn't quite cut it.  Also I'll be using the amp in home with several DAC of different character (transformer coupled CS4398...

-I'm a 16 year old starting out trying to understand how i should go about spending my money. I'm not some intense producer or have plans of building some crazy studio in my basement i just make beats who also likes to record solo artist like myself and eventually bands. I have never had any...

My budget is 200-350 euro, for a box that has both things.   I'd like one that is praised by many users, as to not buy something that might not suit my tastes.   I listen 80% classical music, 20% metal.

I've been getting some help in the official HE-400 thread, but more opinions are always good.  I have a new pair of HE-400s that I'm using with my LD MK1+ and HM-601 right now, but I and willing to spend $400 total on both an amp and DAC.  So far I've been recommended the LD 1+ as an amp but...

Hey, just wonder say for HD600 or so do I still need an amp for if I'm connecting to an interface such as this: http://www.m-audio.com/products/en_us/ProFire610.html  

Could someone describe the bass on the LCD-2 for me. I've heard them before but I wasn't able to listen to much. I'd like to compare the bass of the LCD-2 to the Denon AH D5000. Will the LCD-2 still have the same "rumble" effect if I watch movies with large explosions and what not? In what ways...

Hello everyone,   This is my first post but I know this community has a vast amount of knowledge. I'm asking this question in hopes of tapping just a bit of that knowledge  I appreciate any help and advice in advance.   I have recently bought a new computer which includes the xonar...

In my pc I have an Asus Xonar Essence STX, and I recently bought a macbook pro to use for video editing and stuff, but the audio sounds terrible.    Is there any way to get audio output with the quality of the Xonar Essence STX on my macbook pro?

What is an excellent portable amp for Audeze LCD-2 headphones? Would the ALO Rx Mk3 or Continental, Or Ray Aameuls Sr-71B fit the bill?   Am I netter off with balanced or single ended?   I am using it with a Alogrythm Solo DAC.   Thanks, Ken

Good afternoon Head-Fi'ers,   Been lurking around for quite awhile now and just starting to get back into headphones and such. Long time member over at Overclock.net as well   Anyways, I am starting to piece together a new system and audio setup and would love to have some advice in...

Anybody ever tried both? which one is better for K701's? Thanks! 

i got iphone 4s+shure se215 and i'm looking for to buy portable amp The budget is 60$ i think about cMoyBB what you guys say? thank you.

I'm looking for an upgrade/companion for my DT770 Pro 80ohms. I like how these sound, but the soundstage is too bunched up for some genres and everything gets muddled together, especially in music like this. Also, the mid range is a little too recessed, and the upper frequencies sound a bit...

I was thinking about purchasing the O2 and ODAC. I am debating between a separate O2 and ODAC or getting the one enclosure combo. The reason I would go separate is I can then use the O2 portably (or at least just move it around in my house), and I can't do that with the combo without moving...

I have bought the Sennheiser HD598 and I'm using it combined with the integrated sound card on my motherboard. I want to buy an external soundcard or DAC since I'm already using all of my PCI/PCI-E slots. The furthest I am willing to go is around 100USD unless there is some significantly better...

As I was searching for a good amp/ dac, I decided to save myself the trouble of picking between numerous options and get an O2 amp/ dac.    Now I have to choose between JDS Lab variant and the EHP variant. I can only see the rear view of the former...

I own and enjoy the DACport but recently bought phones with a dedicated amp (Stax), so am thinking about getting an LX, seing as it's purported to sound better. But when I spoke to David at Centrance, he mentioned that the LX is basically a Dacport with the potentiometer gone and the volume...

I have to admit that I took immediate interest when JDS Labs announced their C421 project. Not only because their cmoyBB has impressed me before, but the fact that they are offering C421 alongside with the much acclaimed NwAvGuy’s open source Objective 2 (O2) amp (*End Note 1) is a great sign...

Watup dawgs? I'm looking for a desktop amp/ dac. I have a 50 ohms sennheiser HD 598. I'm a noob when it comes to the audiophile world and a couple days ago, I read an article by NwAvGuy regarding headphone amplifiers. From what I can understand, buying an amp such as the FiiO E9 (an output...
