    Would recommend a Qualcomm certified Quickcharge 2.0 or 3.0 charger for best results.

    Thanks Jason.

    I went the amp route. If you have cans that the SP1000 doesn't power well, it will still sound underpowered. It will be an improvement with cans, just don't have high expectations with something hard to drive.

    My SP1000 just got a new companion received today: a ZMF Verite Closed hadphone. Will the ZMF replace my Shure KSE1500 ?

    But Am I the only one finding the ZMF almost "underpowered" by the SP1000 ? an Amp or upgrade to SP2000 may be necessary...

    The amp will definitely help. I've got the SP1000 w/ amp, and my ZMF Eikons sound anemic without the amp. The amp bumps up their performance to what it should be--more on par with my desktop rigs.

    However, it also turns the SP1000 into a heavy brick. Previous comment about SPK+amp being "transportable" rather than "portable" was spot-on. The value of this combos is being able to take virtually any headphones on-the-go and get the best out of them. I also have SPKM for pure portability w/ IEMs.

    I have another quick question related to the power adapters - if you don’t mind? I’m based in California, but I travel fairly frequently. Am I correct in my assumption that by using the correct wall adapter, I could use your recommended power adapter in other countries?

    Thanks again,

    yes, just make sure a charger model that you buy has Input Voltage: 110~240V AC written on it

    ZMF's Verite Closed sound stage expand well when using my micro Tube amp Oriolus in full balanced mode. Obviously the Verite Closed likes tubes ! Nice finding..... and a proof that the AK SP1000 is underpowered for the VC.

    may be no need for the AK SP1000 amp module or wait for the iBasso dx220MAX ?

    according to Oriolus BA10 specs, the max output of this amplifier is 340mW (32 OHM for balanced
    according to Astell specs, the power output of the SP1000AMP 1.2 Watt (32 OHM) - times more
    may be it worth checking/to compare

    well, the SP1000 do not lack sound volume with the VC, but sound stage; The volume is loud enough but... congested.
  11. Schmeisser
    well i was considering to get ZMF Verite Closed and SP1000AMP for it.. =(
  12. bmichels
    With the SP1000 amp’ it should be OK.

    All of a sudden my 2.5 jack started to need a slightyl touch/push to work with right channel towards the screen....

    Anything i can do to make it work?
  14. Schmeisser
    may be and i would need to know that for sure

    happened twice with my sp1000 and both times they replaced the whole jack module (with 2.5 and 3.5 mm)
