Can a portabl amp really push cans?

As I told the OP, the Mustang is in fact pushing the K702s. It's an observation.
I hardly think the deities in charge of desktop amps should charge me with blasphemy

Look, given the opportunity, I will be happy to listen to, evaluate, and (i'm sure) praise full size amps. Unfortunately, money and circumstance are against me at present. I am looking forward to moving to the next level of this great (and expensive) hobby.



There are a wide variety of headphones which a portable amp can provide sufficient power to drive properly.

The issue here is that those same headphones can be driven properly by a DAP or a sound card as well, rendering a portable amp superfluous at best.

I understand that money can be tight; I had to scrimp and save to buy what little I have. But what Red, Uncle Erik and I are pointing out is that a portable amp is not especially cheaper than a full-size home amp and provides far less performance and "bang for the buck."

A used Gilmore Lite with Elpac PSU can be had for $200 or less; a used CIAudio VHP-1 can be had for the same price. PPAv2, Millet Maxes and various other DIY designs pop up on the FS forums all the time for prices less than what one would pay for a top-of-the-line portable amp. Sometimes even half as much.

The idea that one can save money by purchasing a portable amp is something of a myth; not all home amps have $1000 US price tags. Many, especially DIY designs, but even many commercial designs, are much lower than that.

For the cost of a Mustang, you can get a damn nice mains-powered home amp and still have enough left over to buy music with. =)

The Starving Student is cheaper, but if you have to buy tools, that pushes the price over $100 too.


Right, but the RSA Mustang is not a $100 portable amp. It costs almost $400. If you take a look around, you could easily get any number of new or used mid-level mains-powered amps with that kind of money.

And when it comes to cheap portable amps, the under-$100 range, all of the ones I have used did not impress me at all. For that kind of price range, if you can't do DIY or don't have the tools, you can't go too wrong buying a vintage Marantz or NAD integrated amp and using the headphone jack. I used to use an old 80s-vintage NAD integrated amp for my headphones and it worked well.

I brought over my philosophy from building computers; I can upgrade a few parts at a time to the top of the line, or just go whole hog and upgrade the whole thing...knowing I would end up making compromises.

I got the cans I want. Now I'm working on amps. Next is sound source. Backwards? I know, but it just worked out that way

Like I said, your so-called "upgrade" was at the price of nearly $400. And $400 dollars later you are still "working on amps"...

I'll never forget when I asked Skylab (on his portable thread, bottom of page 217) about how the Pico DAC/amp compared with the $200 Eddie Current Lunchbox. He said they were incomparable.

When I inquired about further details, he didn't respond, and after I felt a bit frustrated, but later I understood his point completely.

He didn't need to "compare further". There was no comparison whatsoever. You could have got the Lunchbox and a good source for the price of your portable.

I sometimes think people around here just get this impulsive desire to have an amp because everyone else here does. They don't have too much to spend, and want one right away, so the portable market becomes enticing. They read about all of the hype created by many around here and end up getting the portable. It becomes their first amp, and being their first amp (and possibly trying to justify the price), they run amok on these threads and create a "cult of personality" around a certain product.

Sure, they look nice, but do they compare? Skylab's "silence" made it all so clear to me...

You are probably right. I stopped looking at the mains-powered home amps after I bought my LD MK IV. I just haven't used it much and so focused more on portables for various reasons (I travel a lot). I have to say that I won't be exploring the portables much anymore because I found what I wanted.

So, now I can look toward other things (amps and sound sources). I really would like to attend a meet. I know there is so much out there I am missing. Also, I need to explore a good sound source. It's kind of silly running a portable media player through a desktop amp. Do you have any suggestions for a good cd player?

And that is why I stick to a iBasso T4 as my portable amp. Small, slim, portable and just what I need for IEMs. If I wanted something to power big headphones to lug around, I'd get a reasonably sized headphone amp or the Lisa III. I don't know anyone who uses full sized headphones on the go or while commuting. It's just a waste.

You should see me with computer video cards

No. I tend to stay in a particular track until I find what I want (single-minded...heh). Once I do, I move to the next thing.
I am not trying to form a "cult of personality" around the Mustang (Heck, I've only had it since Friday!). I was merely letting people know that I was d*mn*d impressed with what I heard. I have too many little portables of different makes lying around. And for people convinced that I was only wasting money on portables, consider that I went through four tube-driven desktop amps (albeit all from Little Dot) before I settled on the one I have sitting next to my chair.

My Dad loves it...he keeps getting all my cast offs

Well the problem is I have tried and offered to pay for iem's for him. He has a cheap pair of zune iem's and pretty much refuses to get anything better. He wants full sized cans for his portable use, which I do not agree with, thus why offered to pay for customs. He really does not understand why I am against using full cans with his zune. He has never heard great quality audio. I tried his 555 from my ipod last night and from his zune and it sounded like utter crap, thus why I am serching for a good set of cans and a portable amp to show him what he is missing. When I get my pico in I will test his phones with it, but I still feel the 555 will sound like crap no matter the source.

Sennheiser PXC-450 noise canceling phones. With the switch set to bypass, they sound very nice.
My walk arounds are Senn PX-100s

We're basically agreeing. I couldn't imagine spending $400 on a portable amp. But I'm also with Uncle Erik in not being a believer in portable amps for portable headphones. I can understand people who travel a lot spending money on a smallish transportable amp like the Lisa III. Personally, I don't want to deal with batteries at all, so I'd buy a transportable desktop amp what uses a wall wart.

Edit: Also, all my headphones that are portable, can be driven from my iPod without any problem.

Does he listen to your setup? Consider "accidentally" misplacing his gear and "allow" him to listen to yours. Maybe he'll come over in time.

I suppose..

Portables should just stick to powering IEMs.
Transportables and home amps should be used for full sized cans.
There are limits on what a portable amp can and should do and I'm sure people lugging around full sized cans won't mind lugging around transportables.

It's hard to find a plug on a plane. That's when I do a lot of listening.

Alright everybody! The truth: I bought the RSA SR-71A Blackbird and the P-51 Mustang because I Like Airplanes. OK?

The fact they got good reviews from portable amp reviewers helped (yes, including Skylab). But I wouldn't have given them a second look if they were named after cars, boats, people, dogs, cats, whatever.

I had the money to spend; I spent it; I'm happy.

'nuff said.

I can't believe I've been on this forum all day justifying myself.
Good night. I'm tired and going to bed.

All I have are customs now so there is no way he can, thus why I am trying to research the matter. IEM's are my forte where he prefers full cans. So I need to study before I give him options.

HK (sleep posting): It's not easy to change a persons mind when it is set. Try to work a compromise, or at least agree to disagree.
