Hi Currawong 

may I ask you about the dragonfly ?

is the SQ from dragonfly overall so mellow ?

what kind of headphone do you use in pair with pico power ?

i saw you use low gain  

thank you 

 

I'm using the Symphones Magnums at the moment. Since the Dragonfly has its own analogue volume control, I was playing with setting the Pico Power's volume at maximum and using the Dragonfly's instead. I'm used to listening with a Stax rig so this all sounds more mellow. I'd say the Dragonfly is a touch mellow compared to, say, an ODAC.

Really excellent sound and build quality.  Thank you, Justin.  As mentioned by others, I love the fact that you can throw extra 9V's in your pack, and be totally off-the-grid for days.

 

Also been using it at home, upstairs (main listening room is downstairs), with RWA/ALO 5.5Gen (Wolfson DAC) iMod/LOD, and Grado's with the Grado adapter (both my button RS1's and HF2's).  Lowest gain setting of course; remarkable detail and (perfect synergy with the Grado's) mids to die for.  Listen to 24/96 FLAC of Band on the Run covnverted to 16/48 ALAC with SOX for loading on the iPod and you will see what I mean.

 

I'll still use my Shadow on planes and trains where space is a premium (and I'm wearing portable closed phones, so there goes the SQ anyway), and my iQube and Mini^3 are rechargable, so they might still get some use.  The iQube had been my go-to for upstairs heretofore.  I haven't done a serious blind A/B yet -- need my wife to make the amp changes while I have my eyes closed, and she has expressed zero enthusiam for this, so I will have to throw a trip to Short Hills Mall (my wife got a dealer-installed option on her Subaru which automatically stops the car as it passes this mall, who knew that was even made?) in to the deal, and she will buy a handbag that costs as much as this amp and doesn't play any music or light up or anything, and will go out-of-fashion before the PP runs out of battery, rats.  But anything for sound science.

 

Anyway without a serious test I will still go out on a limb and say this has the best SQ of the 4.  Will try with Ultrasones next.

I definitely agree with a previous poster comparing similarities to the gs1. Tonal balance is right on.

Yes, it continues to sound great, even as the prototype did.  I have had it for a while now and i don't go anywhere without it.biggrin.gif

I had the SR71-B for a while and the Pico Power definitely sounds better to me. Plus the Pico Power price is a lot more attractive.  Just saying. :)

Thank you Currawong

Ice Station Zebra is now under Pico Power!
Quite impressed with everything so far.
Justin's amps are little jewels.

Subscribe! ... and patiently waiting. Apparently I am in batch 2. Fair enough, I ordered quite late.

 

Keep the impressions coming please.

The search is on for an equally portable source that would "do justice" to this refined portable amp. I don't think the ipod touch will cut it?

post #56 of 367

^I'm "just" going to be using an iPhone 4S.  From the 3GS on, I think they sound pretty good...better when amped!

I seem to have had the same luck with the HP-P1 as a source for the Pico Power as I did the L3. 

 

A bit of curiosity I decided to satisfy was comparing to the O2. For this I'm using my ULN-2 as a source, which is much better than the Dragonfly. After painfully going about level-matching them, very roughly I feel that the O2 gives the impression of a lower noise floor and possibly lower stereo crosstalk, extracting some great micro-detail and background ambience from the very best recordings, but at the expense of dynamics compared to the Pico Power, which gives, for example, percussion more impact. I reckon though that the differences under normal circumstances (ie: not using a $4-figure DAC as a source) the Pico Power is going to sound nicer to use. It is is also, of course, vastly smaller and a heck of a lot nicer built (especially compared to my dodgy casework!). 

 

 

 

Edit: I forgot to try IEMs with it. I am listening with my usual Sony XBA-3s which, due to their impedance curve from hell, play havoc with amps that aren't linear or have high output impedance. The result is excellent.

I have a feeling I would enjoy the PP connected to a DT1350 set, portability in mind.

You will enjoy it. Using the PP without the solo with the DT1350. I use the medium gain.

Very interesting amp...

@ currawong, how this amp compared to your triadaudio L3? I have L3 and love it, but the battery run out very quickly. Im pairing my L3 with fostex hpp1 with iphone, mostly driving my T1
If pico as good as L3 im sure i will have one
