Comparison of latest DAC chips

#1 There is nothing simple about a turntable receiver and speakers. The OP must have no experience with cartridges, tonearms, turntables and phono preamps, the best of which will have an overall cost of at least 2x the best DAC. 

#2 Whoever mentioned that it's not really about the DAC chip, but about implementation, is absolutely correct. The best wolfsons and burr browns can still compete given the proper circuitry engineering. Manufacturers have put in a lot of time money and effort to develop and utilize them over time. The newer dac chips may just me more adaptable to changing times and easier/cheaper to utilize properly. Needless to say that newer chips are more future proof, hence, more practical to buy.
 
#3 My CA Azur 851N uses dual AD1955 and I'm completely happy with it as a streamer (preamp mode sucks for some reason connected straight to a power amp) but I'm researching the topping D90 vs the Node 2i for a friend so here I am. The comments about the AK4499 chip in the Topping DAC reminds me a lot about the consumer feedback on the CA Azur 851N. Lots of air, wall to wall sound, incredible staging,  punchy, not slouchy, etc. It makes me want to believe that chips with this AK4499 is superior but I'm sure its success is based much more in its implementation. I am just wondering if the bluetooth function of the topping d90 dac will work as well as vs connected to a streamer like the node 21 or azur 581n....

Since my thread got kick started, I will comment on my thread and D90. I have had it nearly a year and have listened to it about 300 hours. I upgraded my amp to a Pass XA25. I still use the D90 connected directly to my amp. I have horn speakers.

I agree with the premise of implementation vs chip brand.

The sound from my system is very detailed, clear, great soundstaging, dynamics. I could say it it analytical and clinical but not sure. Since my purchase, I have found some other DAC that would probably be worth a try. Audio Mirror, MHDT and Schiit. These have tubes and would be interesting to try with my setup. For now though, I find the music from my system quite satisfying. I am not disappointed and don’t regret the purchase at all. I don’t see very many D90 come up on the used market so maybe that is a good sign.

I  have many single end device and class A amp. So I would just recommend Topping D50s. It uses  2 x ES9038Q2M DAC chips. I use solar panel changed Li-Battery pack to power D50s for lower noise. It is is a $200 DAC and basically can toss it after years when better DAC come out. I use Tidal , Qobuz and Foobar2000. D50s supports highest DSD512 and PCM 32bit/768kHz.COAX and OPT of D50s supports hightest PCM 24bit/192kHz and DOP DSD64.
