i have mine too, and am equally impressed with the USB DAC coming from my computer. really is increadible on my ALO-780's. i'm hoping to run a set or two of batteries through this amp and hopefully force a bit more oomph into the bass department through breakin... although i am sure this isn't going to happen much. still, really really amazing dac/amp!

Just checked in Audio Midi application for Mac, and it looks like all my USB stuff can be set for 16/48 or 16/44.1 - sorry. The default is 16/44.1, and it still wont go higher than 16 bit or 48Khz.

So if I don't get it wrong, the D3 works this way:

DAC only: using the USB connection, no batteries needed
Amp: uses batteries
DAC+Amp: uses batteries

I am interested in using it as DAC+Amp, so I will have to recharge frequently, even it it's connected to my USB?

Is the D2 Boa/Viper the same, or can it also charge the amp via USB?

D2 Boa charges via USB -- that's why I went with it for laptop usage, so I don't have to worry about swapping batteries.

That is right.
The Amp section of the D3 is always running from batteries,
the DAC over USB power.

I prefer to charge independantly.
I think it is better for the rechargeables to be charged when they are empty not every time when connected to the PC.

Boa charges via USB. Viper charges via an AC adapter.

amp still sounds really really good!

the treble is a bit smoother now, but still very detailed and 'airy'. the bass still is about the same, but its not an issue. This dac/amp brings out the best in any song i throw at it, really awesome stuff!

i am noticing the headphone jack kind of loose when i hook up with my ALO 18ga 1/8" end. I am not sure if its just the connector on the headphones being very large and pulling down on it, or what not. I am going to try an 1/8" extension with different end and see if it fixes this issue (one side of 'phones cutting out and i have to wiggle it a bit).

I've not noticed the headphone jack being loose; check that your endplate is securely in place. If the jack still seems lose, remove endplace and look directly at the socket.

so i got about 60 hours on the first set of batteries. it was sounding very good, then started getting kinda warbly. switched them out, and...woah.

i woulda bought the amp if the sound quality was what it was at the END of the battery life. having juicy battery on tap makes this amp absolutely incredible. absolutely amazing, definitely changing them out more frequently then i got by with last time!!

UPDATE:

Well now i've managed to get over 200 hours on this amp, and there are no changes (to my ears - but then again I've been so blown away I might have missed something!).
I got my HD 650's for my home rig and I just had to try them with the D3, in full DAC/AMP mode, and boy is it sweet, really good sound, very listenable. In a comparison with a Slee Novo out of my Beresford DAC I'd have to say its to close to call - both do a fine job, but perhaps both are missing some of the 'sparkle' that engaging 'wow factor' if you like. Of course I'm comparing the sound with a DV 332 which is a near perfect match with the HD 650.

I'd be happy with the HD 650's sound from this amp, but I tend to lean towards the DT770, possible due to the closed nature, which is possible better for a portable system, as I can't stop my ears from picking up outside noise when I listen criticlly.

Actually, does anyone have any pointers for that? When listening on open cans I find myself straining to hear the humm on my headamp, whilst I should be listening to the glorious sound from the cans!

The Beresford is a fine dac, one that you would be hard pressed to improve at its selling price. However the Novo like other amps benefit from a better source. If you have a better source try it to see if the amps scale up.

Please do not take this as a dis on the Beresford, I am talking about DACs selling for 4 times or more its price.

I'll have a go at hooking it up through my Musical Fidelity A3 CD player, somewhere I might have a cable.
