I have not tried the Pico as a pre-amp. I may try it later though and if I do, I'll post the results in this thread.

I don't think the Pico is lacking bass, rather, its' neutrality simply shows headphones for what they are. Neither the AD2000 nor W5000 are particularly bassy (something that going balanced helps).
Anyway, the fact that you could even have a reasonable comparison between the Pico and several high-end CDP's speaks volumes to the prowess of the Pico's DAC. It performs at least as well as numerous $1k+ DAC's I've owned. I think your comparison shows that Justin has probably extracted about as much as possible from the parts and form factor chosen.
I don't feel that the low gain setting is an issue for low-impedance cans, even IEM's. Sure, you don't have as much range on the volume knob as you might from an amp with little to no gain (  ) but it's not to say that the proper volume cannot be reached. You just need to be more careful in adjusting the volume, particularly with IEM's. The Pico certainly sounds better than amps designed specifically for IEM's, so I think this minor issue shouldn't be a deterrant from obtaining better sound quality. |
That's a good point about my "boringly neutral" comment when you said it shows headphones for what they are - I indeed found that to be the case. And at least in the area of the bass differences between it and the AE-2 that I noted, I believe that's mostly coming from some bass "distortion" off the AE-2's X7R ceramic caps, as I've been informed. I did prefer this bass distortion.
I did think the CDPs that I compared the Pico to were over-the-top, and I did briefly look for products that I thought could serve as worthy competitors but found none. I think
that also speaks volumes about the Pico's DAC prowess. And my listening did form and cement my opinion that the Pico is the ultimate "extraction" from the parts used as you put it.
Oh I agree that adjusting the volume does need to be done carefully with IEMs. A good volume level can certainly be attained with IEMs but I found the precision control lacking, particularly in comparison to the AE-2's Low gain. I needed to be extremely precise with the 32 Ohm UE triple.fi 10 Pro which created frustration, I would've appreciated more gradual fine-tuning that a lower gain would've brought.

I'll take your question as a joke.

If it was, I never saw it mentioned by Justin. On the AE-2, 2 is Low and 4 is Med, and I definitely got better volume control on the AE-2's Low gain compared to the Pico's Low gain, so I'm sure it's probably 3.

Insanely thorough review. I had to wait until I was at a desktop computer to read it, though. Heheh.

Well I once received feedback from someone that my reviews contained no information about the sound that I personally look for from amps and affect my biases, so I figured I'd start adding that part to every review. And as HeadphoneAddict noted, I tried to think of common questions that readers would have so I fleshed out the review with answers to all of those. I tried to compact the review into fewer pages when I saw it was 13 pages in MS Word but really couldn't see anything to remove. Sorry if this makes too long to read quickly but it is at least my definitive review of the Pico.

This isn't meant against you specifically but I'd like to formally and publicly rant about "warm-sounding" amps. I absolutely believe that solid-state amps should not add their own colorations to the sound. I did say the Pico departs somewhat from the HeadAmp sound established by the GS-1/Gilmore Lite/AE-2 but even then, it's not really
that warm-sounding in comparison to other amps I've heard. It's more of what a HeadAmp product
should sound like to achieve an ideal pleasing frequency balance and the mid-range doesn't interfere with the bass or treble at all. There are plenty of other amps that I would call warm-sounding. And I may be in the minority on Head-Fi but I do not desire a warm mid-range from an amp at all and I don't understand why many other people here seek that quality from their amps, it unnecessarily adds to the variability of system-building.
Its a great phone and easy to use and its driven my headphones well so far!
To update in depth shortly.
I loved these buds to bits, they were the perfect everyday headphone. Small and light and comfortable and barely protruded past the outside of your ears. I like the fact that no one can really...
These and the PL50 are terrible quality buds, I went through both of them in less than 8 months. Both times they failed they left me in an awkward position where I really needed earbuds for...
