    No, it does not unless you plan on using the DT880 32ohms version.
    You will either need an external amp or another DAP with a balanced output such as the NW-ZX300.

    For HD600,

    • SPL:97, power:3.33mW, V:1,I:3.333mA
      SPL:94, power:1.67mW, V:0.707,I:2.357mA
      SPL:91, power:0.83mW, V:0.5,I:1.667mA
      SPL:88, power:0.42mW, V:0.354,I:1.179mA
      SPL:85, power:0.21mW, V:0.25,I:0.833mA
      SPL:82, power:0.1mW, V:0.177,I:0.589mA
      SPL:79, power:0.05mW, V:0.125,I:0.417mA
      SPL:76, power:0.03mW, V:0.088,I:0.295mA
      SPL:73, power:0.01mW, V:0.063,I:0.208mA
      SPL:70, power:0.01mW, V:0.044,I:0.147mA

    The A40 should be able to deliver upto 94 dB SPL which is pretty loud. If you listen at 80dB SPL(quietest part of music) and the dynamic range of the music is more than 14dB then it won't sound great. But, most of the music produced today have very short dynamic range with the exception of classical music.

    Thank you for the quantified reply, Very nice. May i ask where is this data from?

    Interesting, the whole roll out. I think it was artificially postponed to clear out the 35s. If you look for a cheap 35, you cant find anymore..they are all gone...they are smart, they did this so you wouldnt have overlapp in which 35s would be half off.

    I’ll be in Tokyo next month and I’m thinking of picking up the 46 with the earbuds. Will this version be multi language. If not where could I buy one in Tokyo preferably since it will be cheaper. If not I will buy one in seoul.

    Sorry to ask a question that has been put before but I can’t be asked to scroll back through the eons. What’s the difference between a nw a35 and 45?
  7. phower
    I calculated it from the spec sheet of HD600 and A40's max output voltage.

    Really think Sony isn't looking to spend the $$$ and change things. Seriously, after the A30 a the designs trial run how could they not move the hold switch to another side and make the PLAY/FF/RW buttons bigger or more spaced out. :worried:

    Well BestBuy has the blue and the grey ready for ship. Both say free shipping receive by Fri 16. Ordered the blue one. Hopefully I will get it Fri as promised.

    A45 add support back for AptX bluetooth and also supports AptX HD
    A45 can be used as a USB DAC with a computer
    A45 supports MQA
  11. alchemist23
    So if I don’t need any of those they’re just the same?
  12. fish1050
    Ah yes BestBuy, I seem to recall they had the A35 available on their Canadian site for all of 30 seconds. Now they don't sell any Sony DAP's at least for now. How are things in Saint Louis! I lived their for almost 11 years and they were the best 11 years of my life.
  13. fish1050
    Depending on who you talk to the sound quality seems to be slightly better. Interface might be more responsive but if you can get a good deal on an A35 then go for it! Here in Canada they sell for the same price so I will opt for the A45 once it becomes available

    Got Shipping confirm from BestBuy and tracking number. Looks like I will have it Friday. So anybody looking for one BB has both the Blue and the Grey ready to go. Kind of regret the purchase but I will give it a fair shot. Not a fan of the fact that EQ doesn't work over BT with the player. My 1000mx2's phone App is amazing and not only can I use eq, but crossfeed and bassboost with my phone, but I can use the adaptive sound control. Not sure if the nwa45 can do any of that. I'm guessing probably not.

    Saint Louis is Saint Louis. I'm sure its the same as when you were here sans an NFL team. Nothing ever really changes here.

    Edit: Turns out you have to connect to the Walkman first, then connect to the headphones with the app, and change sound settings after.
