Excellent comparative study of the amps. Not an easy task and it would drive me nuts after a while. Thank you for the hard work that you appear to have enjoyed and for sharing the results in a very readable form.

good review. would have liked to see how the go-vibe v5 compares to the rest of the pack when listened to with the elpac psu, but that obviously isn't fair to the other amps listed and would require a lot more testing and such and so forth. Otherwise, thanks for the time and effort put into this Very informative and a great starting point for portable amp purchases who sole use will be with batteries.

Thanks for the nice review. I would only have liked to see the mSEED LABS Faith AMP included in it, besides the XTRA X-1. Perhaps the C&C BOX too...and while I'm at it, the Minibox-E.

I actually wanted to include the mSeed, but I kept losing the EBay auctions

Maybe I will get one and add it when I add the Xenos 1HA, which seems to have shipped.

Thanks Skylab for the professional review. I have just received my Tomahawk today and am already quite amazed at its performance. It even drives the HD650s really well - something that I did not expect at all.

BTW, I also enjoy the sound of Jan Meier's amps like yourself.

Thanks again and cheers,
cansman

As of yet, no. But I doubt the defective one has even made it to China yet.

Wow skylab fantastic and very professional review. You have reinforced my satisfaction in selecting (and luck) the PRII to be my first portable amp. Somehow this needs to become a reference source for all those newly traveling down the expensive slippery slope of portable ampland.

Thank you for the well organized and very informative review.

I put a great deal of stock in reviews of this nature.

Good job!

Default Update 1/24/07

I have purchased a couple other portable amps since I first published this review, the Xenos 1HA-EPC and the iBasso P-1, and I got my Xtra X-1 repaired unit back. I have run the new amps through the full battery of tests described above. I have added full comments on the X-1. I have not done so on the Xenos or iBasso amps, but will as time permits. I have decided to do an updated rankings. These are all now in the original review post.

EDIT: PLEASE READ THE WHOLE UPDATE before commenting. As I indicate there, since I no longer have the Practical Devices XM4, I could not decide directly between the iBasso and the XM4, so I list them as a TIE.

So, #3 and #4 in your list are definite? Would you consider it a close enough tie?? Hmmm...

They are indeed very close, and of course, slightly different. From the Headphonia amp on up, the amps were good enough that I could live with any of them happily. They all produced that "WOW that sounds great" feeling consistantly.

Below that, the amps for me were missing enough that I wasn't impressed enough to say I would be completely satisfied over the long haul.

I just got a Porta Corda MkIII-USB in the mail today. But it is not on this list.

Great reviews though. I really liked reading them. Maybe you can try to get people to send you portable amps for free just to test them.
