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,

make sure first and foremost it is the non oversampling dac chip that is used, if not get audionote to do that for you first. Secondly upgrade to balanced with output transformer. Only then should you really consider fine tuning.
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.
