Perhaps you might want to update the list?
AOS Electronics and Xenos (alas!), are no longer in the headphone amp business.

I didn't see this one posted.

This is where I got mine from:

www.miniatureaudio.com

I loved my purchases, took only a day to get here and the prices were really good for me. At least in the range that I can afford to pay.

out of all the amps listed on the first page ( the updated one), what amp would be the best for under 300 $ ( but preferrably less ) to use with darths? Preferrably should have a dac but it's not essential.
thanks

Personally, if Im looking for a DAC and a Amplifier I really like the Fubar3. Its a great little gadget, love the casing and quality and its also under 300$ so pretty affordable IMO.

Hi all, I've been out of touch with reality for a few years, what happened to Meier audio's portable amps? he's only got one listed on his site now and it's the one for us head-fi'ers. I was hoping that he had upgraded the porta-corda line or at least had some mods for it.

I was wondering, would the PA2V2 amp be a good match with my creative zen v plus and modified grado sr80's

When I had a PA2V2 I paired it w/ an SR125 and ER6i. I felt they had good synergy and enjoyed the sound. As a first amp or an starter amp it is IMO a nice one.

I don't know if this has been done before, so maybe I am reinventing the wheel. I will start and maybe others can add to this. Maybe we could get a sticky if this gets filled up enough. I would define a portable as having battery power. This list also includes portable DACs, no longer sold amps, and DIY amps. Prices listed are in US$ dollars.

Man, this list is completely outdated.
post #148 of 169
Hi All,

New to this post so please bear with me...

To be efficient here is my question (and maybe I am insane)..
I am looking for advice on purchasing a portable amp/DAC that is on the small side that can actually drive bookshelf sized speakers. It must have the following:
-one USB input
-one optical digital input
-one stereo RCA input
-be easily switchable between these input (a remote would be amazing!)
-the DAC needs to accept 96khz and possibly upsample 44.1 and 48 to 96khz

Is this possible? Is there a product that can do all this? I have looked and cannot find anything. Perhaps a 2 part solution would be best--an outboard DAC and receiver?

...I am going out of country for possibly 2 years and would like to pick something up that can handle SACD output from my PS3(optical), iTunes output from my mac mini(usb) and be able to run an unforeseen third device through the RCA's. Also it'd be nice if this magical piece of hardware could then be incorporated into my soon-to-be high-end setup once I return home.

Thanks for listening all. If anyone can point me in the right direction on this I'd be grateful.

Please feel free to drop me a line at brettra2@yahoo.com.

Many Thanks!
Brett
