Upgrading AudioNote DAC2 older version Help

Hi,
I own an older AudioNote DAC2 and plan to upgrade some of its components. Could anyone provide me with any information of which part should I upgrade and using which type of components (ie. using which BlackGate?)
I currently had its tubes replace with the Amperex 6922 PQ, however, the effect was minimal. I hope by using the BlackGate, its performance would increase near/similar to the newer DAC2.1x.
Thanks so much.

Regards,
Adinata

A big improvement that AN itself upgraded was to remove the filters from the DACs. Does your DAC still have a filter? It's not simply a matter of removing it; the internals have to be reconfigured slightly. IME this was a worthwhile upgrade.

Check out the Audio Note Kits forum. It's somewhere on the Audio Asylum. There may be parts info discussed.

Thanks for all.
Yes, the DAC-2 that I have is the one with oversampling.
I try to get more information from Peter of AudioNote.uk, he is very nice and helpfull. I hope it would be true that the older DAC2 could be upgraded to 2.1x or even the Sig.
Thanks so much.

Hi,
Is there a big improvement when comparing the upsampling-AN DAC with the non-upsampling one? Because, actually I feel that the one I have (w/ upsmapling) is very musical (although the vocal is more laid-back).
Thanks

All I can say is that all the dacs that are non oversampling are by far the most superior sounding and musical dacs- even in a £200 Far Eastern DIY JOB. So in my mind it is the dac rather than any other component that is foremmost in importance. Peter should be able to verify this.

I guess I have no choice other than replace my old DAC-2 with the new one/ other DAC.
Thanks so much
