Okay, I know something exactly like this thread is always on tap here, but I've been searching and reading, and -- though I've really learned alot from this site about what's out there (heck, I've even started reading reviews of opamps!) -- I'm running into the limitations imposed by my experience and non-engineering education, and I've begun to find it difficult to compare apples to apples. Many products (or even makers!) are no longer around, others have been updated, and prices have risen. So I'm bringing it up again. Apologies for the long post, but I'm hoping this thread will become an all-in-one resource for newbies like me and people of limited resources.
I've got a Zune 80gb and just purhased some UE super.fi 5 pro IEMs (21 ohm impedance, 199 dB/mW sensitivity) . The UEs are an enormous improvement over the stock "premium" buds, but really reveal the limitations of the Zune's internal amp (and lack of equalization). Highs are great, but mids lack just a bit of definition and presence and lows aren't thumpity enough. So, I clearly HAVE to have an amp.
You'll also want to know that I'm using WMA lossless files. Not as good as FLAC, I'm sure, but it's a portable, and ultimately, I seldom use it in really great sonic conditions. Isolation may be great with the IEMs, but that airport/jet engine/taxicab drone isn't ever going to disappear, so I don't think buying a $300 amp is really appropriate. I can't justify more than, say, $125 for a portable amp, and really would be happier if I could stick to around $50.
$50, of course, would limit me to a cMoy amp, perhaps one by biosciencegeek. I've also considered paying a bit more for one of blackinches'/three3three3's cMoyBB v2.01s. Juice2214 sells for $35, which is even nicer. In the other direction, Penguinamps' Royal Amp is available at $99. Should I not even consider a cMoy? Why not? If I should consider it, does t3t3's PCB construction offer a real improvement over the other two (at least theoretically)? I do like the idea of being able to easily switch opamps out easliy.
For that matter, should I just be grabbing a FIIo at their weirdo $.01 cost/$19 shipping pricing? They seem kinda noisy compared to other options, but the price is right. No volume control, though. (on the other hand, no lineout for the Zune...)
A Travagan's colors ($59)? Like the FIIo, there's no volume control.
How about a Mini-box D at $80? Love the form factor, but perhaps that volume pot will get noisy?
The Headroom Total Airhead ($99)? I'm not sure what components it uses, which is troubling, but not unique. It's rather bigger than most other options, too. But it does have some crossfeed, which sounds like kind of a good idea.
Or the C&C Box+ ($109)? The older Box v2 fared poorly in Skylab's comparo, but C&C claims the new one is significantly better, and the size/form factor seems lovely.
Rockhopper's selling a Mini3 at $125. Based on the giant review roundup posted by Skylab, that represents a lot of bang for the buck. But it's also a lot of bucks, given my self-imposed limits. Is anyone else building them?
The iBasso Boa is crazy expensive, given the conversion rates right now. Looks like over $160 US right now, and that's out of my range (and into competition with some better products I think).
The Practical Devices XM4 may be a consideration, as they're available on eBay right now (01Jul08) at $130 Buy-it-Now. But the company's website indicated that they're suitable for 'phones with impedance as low as 23 ohms...which is 2 ohms higher than the UEs. I don't even know what would happen if I tried using it. Anyone? Anyone? It brings up a good question: how much amp is TOO much amp, when you're talking efficient IEMs?
I've seen various other options in the price-range, but honestly, I'm getting to the point where I can't keep them straight. And I'm sure that wiser heads
can point out anything I'm missing. So, please, wiser heads: do your thing!
