Best way to connect iPad to integrated amp

Might want to see if this will work for you - HRT LineStreamer+

I use  a different model a HRT istreamer to use my ipod classic in my headphone system . Good sounding DAC for the money

The iPad doesn’t have a USB port. Won’t work. You need to buy the camera dongle which comes with a USB port and plugs into the lightning connector. 

Stereo5 is correct you need the adapter. They have one that allows you to skip the need for a usb hub and use it with your charger.

For just about the same money as the cable you can get a Klipsch Gate off of Amazon and use your ipad to control the Gate around $30 shipped. 

The sound quality is fantastic and I prefer it over the Bluesound Node 2i I had. 

Before the Node (ive had the node 2 and 2i) I was using an ipad as a streamer with the dacs in a Hegel h160, Outlaw rr2160, Peachtree Nova 150, Centrance Dacmini, Devilsound HD, Jolida Glass and a few others but was not happy with the sound. 

For the price and option to return it you can’t go wrong. 

I have seen the 3.5 to rca stuff. I was trying to find out if there is a dac/ streamer that bypasses the iPads internal processing. I don’t believe the sound coming out of the headphone jack will be all that great
