The formatting of this thread is: The impressions of each amp. Then the rankings on a cumulative level, although SQ based, it's not the sole reasoning, as you can find that out from most every review out there. With portables, I believe practicality plays a HUGE HUGE role. After the rankings...

Before - post count around 100, a modest rig for home and portable: Since then, my MS-1 is now a MS-2, the Cmoy has been given to be friend to be confiscated by the government (Thanks, JFK security) and the Ipod is the only thing left. A few months later... Post count - 1500. Portable...

Every time I check into this forum, I find more and more threads recommending portable amps for headphones like the K701 and the HD650. What? I have not heard every portable amp out there, but I've owned and heard quite a few and currently own a LaRocco PRII, an SR-71 and a Rockhopper mini^3...

Hey guys, I bought myself a pair of B&W P5's as I was tired of owning poor headphones. At the time however I did not realise that a good pair of  cans was only a start to achieving amazing sound quality. Since then I have started updating my library to Lossless Format, and I am now thinking...

I have listened to and owned some great headphones in my time and I recently purchased a pair on NAD Viso HP50's on the recommendation of Tyll Hertsens great "I Love These Headphones" review on the product.    When I first got them home, I opened the package and thought they were not the...

Hi everyone,   I am currently looking to buy my first portable amp and have narrowed down my choices to ray samuels, but am unsure which model to buy...this is where i need your help   The amps i have narrowed down to are the shadow, tomahawk, hornet, predator, sr-71a and the p-51...

It has been about 9 months since Rob (Vorlon1) and I did a portable amp comparison. Since then I have had an idea of going back and adding additional amps. I hope that the additional listening time and perspective of all these months allows us to provide a better insight especially as we all...

I was thinking that it might be worthwhile to start a thread listing the existing portable amps along with their price and website link. No reviews here, just a list. I have spent so much time trying to determine what options I have and would have loved to have a single source to get a list of...

Hi guys,    I am fairly new to the portable amp idea...but have decided to invest in one for use with my iPhone 4S and iPad 2 (both of these containing Apple Lossless Files).   The question is, at the moment I have the option to purchase either the RSA SR-71 or the Fostex HP-P1. Both of...

Following my thread with regards to the Fostex HP-P1 or SR-71.   I have opted for the SR-71....mainly because the amp is better than the amp in the Fostex....it should provide me an increase in sound quality from my iPhone 4S using Apple Lossless files and it provides an easier upgrade path...

I've heard suggestions for the ultrasone pro900 but none for the audio technica a900x is there an amp that could suit both if not could you suggest a portable amp to suit either of these headphones, thanks.

Hey folks.  I'm new here.    This all started three days ago because I was looking for a headphone amp for my laptop... Now I'm the proud owner of a pair of AKG K702s, and I still need a portable amp!  I can see already this is going to be an expensive hobby...    So after a lot of...

Hi everyone,   Suppose I have a backpack ready for hi-end audio. Suppose I'm not strong enough to carry things like RWA Isabellina HPA with me. For simplicity, let's limit setup with 4lbs. What components should I choose?   Source: is there anything better than battery-powered Apogee...

Hey all, I am planning to get the HD800's in a couple weeks and obviously, I can't drive them to any sort of decent level without a decent amp nor will anything sound great without a DAC.    I've mainly dabbled in portable audio so most of gear consists of IEMs, portable amps, LODs, etc. so...

Hey there guys. I am currently considering to assemble a portable hi-fi setup, consisting of the following items:     iMod 5.5 80 GB ---> Emmelline "The Blackbird" SR-71A ---> Sennheiser HD800 ( with a Moon Audio Silver Dragon v3 cable )     Can anyone confirm the Senns would sound...

*By truly portable I mean it hardly adds any additional weight/bulk to the MP3 player at all...   Is there anything that is that small and can push full sized headphones easily and...sounds good?   Thanks a lot in advance.

I have been in this game for as long as I can remember. The game I speak of is this ongoing quest we all seem to be on concerning the love of music and the way we hear it. It really would only be worth documenting when I got my first turntable. I was about sixteen, and I loved the sound of...

Hey guys. I kept reading that for high end headphones, you would want an amp. Problem is I only listen to music when I'm on the go. Do they have portable amps for the K702? Why do I need an amp? It is a 62ohm headphone. Would it not sound good if I didn't use an amp? Just out of curiousity, are...

I'm looking for some good headphones for classical music listening - from solo violin to big symphonic Mahler. Right now I'm using Grado Sr125's and they're a little too bright. I'm also looking for something with more depth in the soundstage but still clear and articulate. As of now I've...

I have been listening to my K701 a lot lately and really appreciate its soundstage and smoothness. However, sometimes I feel a bit like it bleaches the music in comparison to my Dyn audio speakers, and even the tone of my K81DJ. Sometimes it feels like a forced neutrality even when the music...

I am a fan of HD25-1s simply because of its portability, isolation and surely the sound. My first HD25-1 is the most common version, HD25-1 II, which comes with the 1.5 metres steel cable, terminated with an angled mini stereo plug.   Pros of  HD25-1 steel cable (523874 replacement cable...

My 1-year-old SR-71 started to act up and "brown out" a bit. Tried new batteries, tightening the thumbscrews, but the problem still persisted. Ray took it in no questions asked (it is still within warranty, of course) and had it shipped back to me as good as new in just a couple of days. Thanks...

Hi Guys,   I just returned after almost 5 years of deployment and while in field I lost my Etymotics ER-4P. Can you guys recommend some good IEMs? I also have SR71 amplifier. I mostly listen to classical, audio books, new age (Yanni etc) & Eminem (mainly in field for morale boosting). Here...
