Advise on R2R DAC

[jigarpatel]

Useful information, thank you.

My current RCA cables are Mogami neglex 2497 which was suggested to me for a warmer sound. I might looks at a neutral/bright cable now. Any budget suggestions please?
Also, I am planning to bring the Anode Acoustics tube pre. Will try out different combinations with DS DACs and the Metrum Octave, hopefully over the weekend.

I have upgraded from Mogami 2549 to Oyaide Neo D+ Class A RCA Cable.
If someone carry for you from Japan, it will cost less then 5k.
I am using it between Areas 2 and Naim Nait 5si.
