    You probably already made up your mind but I gave you some bad information that I should clarify for everyone.

    Only the INITIAL load on 200+GB takes 5-10 minutes. Restarting your device only takes a few seconds.

    That would be very annoying if every restart had to completely rebuild the library. That is simply untrue. It does NOT.

    However, if you swap between 2 different cards it will rebuild the library each time.

    I have not heard that from others who own the A45 and I am sure iem's/headphones used are a factor. Also the sound should settle some with extended use. That is why I never buy a DAP without demoing first as user opinions and gear used to listen vary greatly.

    I thought you could use eq over Bluetooth, but you had to reset to SBC. Don't have my A45 nearby, so cant check right now.

    Hi everyone! Does anyone have information on:

    1) The output impedance of these? Looking for sub 1ohm if possible so that they match well with efficient IEMs (since power output looks quite low)
    2) Anyone used these with the Pinnacle P1/PX or headphones like the HD600? I'm worried these don't have enough power to drive them to a good volume.

    Thank you!

    Nope cant use anything over Bluetooth with A45. LAME! :triportsad:

    P1 is fine, Hd600 Amp pls
     
  7. jamor
    No this isn't designed for 300 ohm cans.

    Thanks! The Pinnacle P1 is 50oums, 96db sensitivity. Does that sound alright?
     
  9. jamor
    Yea that'll be great.

    By any chance do you know what the output impedance of the A45 is? And is the battery life advertised accurate?
     
  11. jamor
    I just got mine but so far the battery life feels pretty impressive.
     
  12. gemmoglock
    How's the sound compared to what you had? Does the s master amp over smoothen tracks?

    I'm getting about 14 hours of battery life using ANC Bluetooth LDAC volume 80-90%. Wired gives me about the same if I leave the Bluetooth on on the A45. If I go into the settings and turn off BT, getting about 20-24 hours wired using ANC volume 95-100. Most of my files are LAME 320, but 1/4 of them are FLAC.

    Well compared to my Modi Multibit & Project Polaris stack---->Coaxial Digital Cable ---->PC Not as good. But next to my LG V10 Quad Dac and Microsoft Zune it sounds awesome! It does feel more musical because it does a better job with sound staging where V10 everything is kind of in your face. Definitely a keeper.

    Thanks for sharing!

    Haha I'm not stretching for a desktop setup anytime soon. That's interesting regarding the V10, I am on the V20. In terms of sound signature did you pick up anything, like is the SABRE on the V10 more bright/glary in the treble or that's not an issue for you?
