@RIGATIO Maybe it's a good time to try something new from A&K - with dedicated LineOut and PreOut that Astell&Kern Kann Ultra has.Last weekend i tried to take the sp1k+pa10 sandwich outside with me. I managed to fit it in a pocket of my jacket lol. The sound was even more impressive when i was outside because it made an even stronger impression of the music playing somewhere out, like there was a live performance. I still stand by my first opinion that its the best "portable" ive ever heard and hoping that some day there will be a single device able to perform like this combo- a fully blown high class stationary rig in a pocket.
Btw, i think the pa10 pairs extremely weel with AK daps, especially their flagships. But i think it would also pair very well with something like the Hiby r6 pro II which has a very well implemented highest quality dac. This dap alone lacks power and stronger dynamics but this is where pa10 would enter the game, providing this amazing class A amplification to fulfill the sound with a bit of warmth and strong punch.
I saw a very good price offer in the ads here. (1000 Euro !)
But first check in the store how it plays with PA10.
Generally speaking, I didn't say anything and I don't encourage change.
