Review: Portable amp roundup! 56 portable amps reviewed and compared - FINAL update 12-20-10... - Page 121  

Thanks Miguel!

Wow, thanks for the very kind words Steve!

Indeed - Larry will be able to give you a nice comparison between the 2Move and the iBasso D2 very soon. I am expecting to get a Decware ZenHead in a few days, and will be focusing on that.

Thanks so much for the kind words. But I don't want to put the rankings at the top - it would just encourage people not to read the review itself.

I currently have the TTVJ Millett Hybrid and the Decware ZenHead in the house, and will be reviewing them soon

I have just added the following to this review:


Update 4/9/08

I was able to listen to this amp under TTVJ’s loaner program. The PMH is of course the only portable amp with tubes in it that I am aware of. But it’s a hybrid – the tubes aren’t used to drive the headphones directly. Based on what I had read, I expected it to sound tubier than it did. But there are some sonic attributes that can probably be ascribed to the tubes. Less happily, the tubes are also likely the reason that the chassis rings very audibly through the headphones if tapped. This is really a bummer for a portable amp. It means that while it is portable, care will have to be taken while listening not to bump it, or unwanted ringing will overlay the music.


Build Quality: A: Very attractive and sturdy chassis. I guess I won’t subtract here for that annoying pinging…
Treble: A-: The treble is reasonably clean, transparent, and neutral. As I expected the amp lacks a little top end extension and air, but not nearly as much as I thought it might. I don’t think the treble is a real problem, generally, unless you try to use it with dark sounding headphones.
Midrange: A+: WOW. Simply gorgeous. Cliché or not, I have to assume this is due to the tube impact. But the mids were musical, lush, detailed, clean, open, and very enjoyable. The amp’s strong suite, no doubt.
Bass: A-: Full, punch, and fat. Perhaps a little loose. Could have a little better depth. But it was very enjoyable nonetheless.
Neutrality: A-: More neutral than I expected. Aside from lacking the very frequency extremes, it is essentially neutral . In fact, I was surprised to find it more neutral than the Decware Zenhead, which went through the review process at the same time.
Soundstaging: A: Great depth and width, and a very palpable image. Excellent performance here.
Transparency: A-: Occasionally just a bit thick sounding, but generally very transparent.

The TTVJ PMH provides very good, and in some respect truly excellent sound. It’s generally well built. But it’s at the very top end of the price curve of portable headphone amps, and for my $450, for portable use, I’d prefer the iQube, which performs better overall and doesn’t have that very annoying pinging/ringing. It might be better to leave the tubes at home.

Conclusions (4/9/08)


OK, so now it’s now 38 amps! Here is my view on how the amps stacked up. Note that the sum of the "Grades" I give does not always tell the whole story in how I rank them, since the whole is sometimes greater or lesser than the sum of the parts, and I am often forced to split hairs here, since the list has gotten so long. Also please note that even if these amps include a DAC, that DAC performance was NOT a factor in these rankings AT ALL. Also, for clarification, this ranking is based on sound quality ONLY, and does not take things like size or battery life into account.
