Probably because the volume control on iPod is digital and it affects the digital data directly before it is outputted to the HA-2.

But when ipod classic link sony PHA-1、2 、 3   or solo-r 、solo-db      ipod classic can not adjust the volume.  That confused me a lot.

That is usually because the DAP when connected with digital audio usually have their volume locked to fixed. The problem with this is that you run into problems where IEMs and other high sensitive, low impedance headphones will be too loud, even at the lowest volume, when relying on the headphone amplifier/DAC's volume controls.
 
So to allow customers to use the widest range of headphones with the HA-2, we have have opted to include the same chipset in the HA-2 that is used for the iOS Camera Kit. This allows the iOS devices to adjust its volume internally to compensate for any additional trimming that needs to be done to obtain a listenable headphone level.
 
Obviously, if your headphones don't require any digital trimming in the DAP, you will want to increase the volume on the DAP to its fullest volume level and use the HA-2's volume controls for the best dynamic range and accuracy.

As with anything digital, setting can be changed. If it is any concern, just max it out on the iPod and adjust via HA-2.

Hi,
 
I guess no one can answer the following question due to lack of experience with that device. I saw on the Synology homepage that a number of DAC/amp combinations are supported to be attached to the USB port of my Synology DS214+ NAS, so Audio Station app on it can playback music directly via the USB port. It would be interesting to know, if that works with the HA-2 as well. Maybe someone owning the HA-2 sooner or later could test this combination. I placed the Synology next to my router in the living room and it would be great to attach just a small device like the HA-2 to it and listening to music on my T1 directly using the NAS, which lives near to the couch

well not a major deal to whine for infact great so you avoid metal-to-metal  or metal-to-plastic contact from yoru dap or phone thus avoiding scratches

Anyone else here by the HA2 for the main purpose to watch movies with an ipad? I travel a ton and normally watch movies and crush episodes from TV shows to kill time on flights. When I travel with my wife we daisy chain two B&O H6s from the ipad which IMO isnt nearly enough to drive that. I ordered the HA2 to act as a portable home theatre device. 
 
Anyone else do the same?

@ClieOS, what cable did you say will allow me to use my A17 as a digital transport and use the HA 2 as the DAC/Amp? Sorry for asking again. Cheers.

To use A10 series's USB Host function that supports USB DAC, you need the WMC-NWH10. However, I can't confirm whether HA-2 is supported or not, at least not till I get the HA-2.
