    Looking for an amp that is smooth and warm. It doesn't need high bass, not what I mean by warm. It just needs to be as little fatiguing as possible, while having 0 static noise (Hizz) when nothing is on and at g ood volume. Been looking at these from Audio-GD. The R2R15/S15 uses something called: R-2R Discrete Ladders. 11.28 uses: Sabre ES9028, 11.32: Sabre ES9018 and the 12.1 uses Dual WM8741.

    Which one wuld best fit my needs? The 11 series should be analytical as a base, but there is an ability to make the sound warmer and smoother it say. And tey seem very highly regarded. But whihc one is better, is the ES9028 the higher-end or succesor to ES9018? Also the R-2R I've read a bunch of great things about, real warm sound from what it seems, so perhaps this is the one for me? I'm kind of low knowledge in this area, hope someone out there with knowledge on the subjects can guide me in the right direction. :)

    Also. I'm not looking for a Tube Amp. It sounded super interesting in the beginning, but the heat, how big they are and the dangers of starting a fire. (Heat especially being an issue, since it's close to me, and PC. And summer days already unbearable enough as is)

    In advance, I thank you alot for your time in reading this. And I wish you an A1 day. :)

    Narrowed it down to either the R2R15/S15 or the NFB-12.1. The 12.1 is 100 dollars cheaper. Any suggestions? :frowning2:

    It's damned good for its price and it has this typical NOS sound without sounding too warm. At this price a R2R DAC is amazing.

    Experimental version before the 11, which is the "final version"... Until they make a newer version. :D Less expensive, and lacking a module to help with lowering the soundfloor or whatevr it's called. I asked Kingwa about it. But it also seems to be a lot better build the 11, since it's the "final product". But I'm still very happy with the 15, but if I where to buy agian, I'd go for the 11. (Have not tried both, and 15 is still amazing. But noisefloor can be somewhat high when using gain especially, and perhaps that module added would help with this.)
