I used my iPod Classic as the source with mostly lossless files on tap with genres covering a very wide range. It was with a smile on my face that I flipped the power switch, experience a short snap as the amp powered up and then was greeted with was blissful silence, which as I've stated in past reviews is exactly what I expect when I turn on a professionally built piece of audio gear. Double that expectation on a portable device that it likely to be used with highly sensitive IEMs. That's not to say that if you crank the volume pot to max on high gain with no music that you won't get a little hiss, you will, but if you're listening to IEMS (or most anything else) at that point it won't matter, you'll soon be deaf. In the usable volume range on all three headphones that I tried there was nothing to be heard even without a source connected. Channel matching was also superb, staying equal all the way down to undetectable levels, which is something that plagues many a portable in my experience.

If it sounds like I'm having a hard time finding a fault it's because I am. This is a fine bit of kit. With the HF2s, which are pretty neutral for a Grado, I was impressed by the amp's ability to render high frequencies without getting harsh. However the real surprise came when I cued up one of my favorite demo tracks with my recently re-acquired HD600s. I'd simply forgotten how competent these headphones are. While clearly not as bright as the HF2s the 600s snapped to attention with crispness that they simply lack when driven by my transformer-coupled home amp (a DIY creation). Even with the HD600s I never had cause to use the amp on anything other than the middle gain setting but it's nice to know that if I picked up a pair of orthos I'd still have the necessary headroom to take them with me on my next trip.

Overall the Pico Power is a highly talented, multi-faceted portable that isn't likely to leave an owner wishing they'd packed (or purchased) something else. It's small enough to pocket, has enough battery to easily survive a coast to coast flight with layovers and a week worth of nights in a hotel and is powerful enough to allow you to plug just about anything into it. So if that sounds like what you're after I don't think that I can give a higher recommendation.

Ο InnerFidelityς πάντως ισχυρίζεται ότι μπορεί να οδηγήσει σχεδόν τα πάντα.
Αν αναλογιστούμε το πολύ του μικρό μέγεθος με την παραπάνω δήλωση... οκ... ίσως να πετυχαίνει το σκοπό του και να δικαιολογεί τα λ7 που ζητάει...
