Hello I currently have a JDS Labs C421 (OPPA227) and an ODAC. I think it's time for an upgrade from a portable amp to a more powerful desktop amp and perhaps a new DAC as well. I enjoy this setup, but can only imagine how much better my setup would sound with a powerful desktop amp. My current...

using shr940 on desktop, has right now E10 + BB cMoy really like (and always using) the Bass-Boost feature...   listening to  Classical Alt. rock Electronic (new-age, chill-out, etc..)   what would you do ?   thanks! /Eyal.

I just recently bought my first high quality headphones, Grado Sr 80i. I am so impressed and I love the soundstage and I think that the treble which some people complain about being to sharp is perfect. However, although not a bass head i would like to increase the bass on the Grados with out...

I have KRK 8400s and they are nice and all but I'm looking for an upgrade. Max will be $400 for everything. If it wouldn't be a noticeable difference in quality then I will not bother with an upgrade. Or I can just buy an amp as I do not already have one. I listen to everything including a lot...

I narrowed down my choices to these amps (JDS Labs C421 and Fiio E11) ... the iPhone is my source of playing music ... Are the differences are noticeable ... I want to use it on-the-go ... I know the prices are very different but does the C421 worth the investment  ... sorry for being noob guys :) 

Just received my Schiit Bifrost,(BF from here on), DAC to run my iMac audio library through my Lyr/LCD 2s. Had been DAC-ing with the JDS Labs happy little C421. No problems with that, gorgeous sound. Checked to see that my iMac recognized the BF...there it was, in the output options list...

Hi all,   I'm pretty new to amps, so I'm not really sure what to do. I'd like an amp for my headphones to enhance my listening experience but I'm not sure what to get.   Is the JDS Labs c421 a good match for my modified Grado Headphone?   And which is the better choice...

Hi guys! I need a little help here :D i am looking to buy a new portable rig iPod > ??? > JH16 I am looking for a balanced sound, slightly towards bass. Since my knowledge on the audio market is narrow, I need help on this ^^ My budget is SGD900 Another detail would be that the input...

Hello-I've decided on a pair of 1964 Ears V3s and have heard that they greatly benefit from having an amp (of course). Now, the question is exactly how much I ought to spend. I have allotted a $300 budget for an amp, but feel as if it may not be necessary to spend all of it. So far I've seen the...

I've been reading a lot of amp comparisons and reviews here and elsewhere. I'm looking for an amp to pair with my Shure 535SE IEMs. A lot of the shoot offs group amps by budget under $100 or $200 or $300 and up. This makes it hard to find comaprisons of amps on opposite sides of the price...

Title says it all.   I have been pondering over this for a few days, its for a friend, I suspect and AT or Beyer is the solution, and I am not familiar enough with those brands.   Criteria: Circumaural - comfortable Atleast decent isolation (leakage not an issue) pretty much drowning...

Got a cMoy BB 2.03 2x9V and for some songs the bass is sounding a little more crackly that I think it should, my question... is this a lack of sufficent power from my amp or an issue with audio quality   Here's the Song where I first Noticed the lack in bass   Nujabes Luv Sic Part 1...

hey guys,    Anyone recommend any particular closed-back cans for taking places and preferably with a decent case so I can store in my school bag and not ruin them. Probably willing to spend approximately 300 USD, but could slide a bit either way.    I'm one who mostly listens to rock...

Hi I'm a Newbie here! I was planning to get the HiFiMAN RE262 IEM's which are rated at 150 ohm with a sensitivity of 95 db. http://hifiman.us/Products/?pid=101 My iPod amp is the JDS Labs c421 http://www.jdslabs.com/item.php?fetchitem=c421 My friend was just telling that the c421...

Hi.   Long time reader, first time poster.   It's obvious that my Galaxy Nexus phone is not doing my Etymotic ER-4s justice so I'm thinking about getting a portable amp.   As far as I know no one is able to do USB audio on the Galaxy Nexus just yet, but that might change. I also have...

I am relatively new to head-fi and am even more new to iems, but i hope this will provide some at least useful information on the re-zero. Now that i find myself on the go more, i've immersed myself into the world of iems and have decided to upgrade to the re-262, in memory of the re-zeros i...

Currently have Dr. Dre Beats. (They were a gift). I was wondering if it would be worth selling them, and buying the headphones mentioned in the title (HiFiMan RE-262). Also, if I could get enough money for the beats to purchase them. They are used, but have 0 signs of being used. Would also be...

Good morning,   I am in a bit of a quandry with regards to whether I would gain any major benefits from using a portable amplifier with my iPhone / iPad?   At the moment I have fairly easy to drive headphones (Grado SR80i's / Beyerdynamic T70p / Sennheiser IE6) all of which are used with...

Hey. I currently own a Fiio E11, E6 and an E10. I use the E11 primarily. I got them initially because of the pricepoint and as it turns out they are fairly highly rated on here. I saw the shootout thread also. I am considering getting another but if I did I would want something that would...

Hello all, I'm currently using a Xonar DX and a C421 headphone amp. I've been doing a bit of research to try find at what level to properly set my sound card's volume, but there doesn't seem to be a definitive answer so far.   I had read that setting the Xonar DX to 100% volume was the best...

TouchMyApps review is live.   In the last week, I've had the pleasure of listening to the new Fischer Audio DBA-02 MKII, and along with them, a combo I feel really matches, the GoVibe Vest. From what I understand, the name comes from old view or TW cameras. Who knows.   What I do know is...

Hey guys so I was looking to replace the Fiio E11 with a better amp. I think it is a great amp but there are a few things Id like improved with a better amp:   1) Better instrument separation (not necessarily wider soundstage but it would be a good benefit and might be necessary) 2) Better...

It's been a long time coming, but I finally purchased my first headphone amp this week, the luck device in question being a JDS C421 with the OPA2227. I didn't really think that I would need a headphone amp considering my current collection is fairly low impedence-wise (highest being 44 ohms)...

Just Plain simple ill buy the DT 770 Pro 250 , i want to know which Portable amp (see here can could prolly fit in my pocket ) i should use . (0-100 , i can go to 130 BIG MAXIMUM if its worth it ) I know theres a thread with 8 review for 100$ and less but lots of people say E11 won't be able...

I wondered if anybody could assist in me choosing a new portable amplifier???   My set up:   Iphone4 (not s) - music is lossless or 320kbp's, dance, pop, etc   Sennheiser hd 25 1 ii's - stock cable   LOD - silver plated copper   I did (until last week) have the fiio e11...
