Well - It was going to be the end game DAC yes. Just found out the output impedance is to high for the Dynahi. So after I get the Dynahi build I'll try it out and see. If it's a no go I'll be on the DAC hunt again for the Dynahi. However, the AMR is not going anywhere.
Looking at the Lampi with Deulands or the Metrum HEX.
Nice that you have considered the Lampi as a positive one when you showed doubt it would sound good when I mentioned it a year ago lol. I've been put off buying a L5 due to the inconsistent builds and build quality with the units I've seen internally online and the 2 L4's and L5 that have passed through these hands, I still consider it a good musical sounding DAC and all but Iuno I'm back into spinners. Good luck.
Regards cables sounds like you need something with a bit sparkle whilst maintaining clarity from the output of the DAC's if you're running bal or rca's, the Crystal Cable piccolo's should do the job nicely.
