Phono 2 upgrade/modification

Hello,

Whilst taking at look at the new NVA website I noticed that the most recent incarnation of the Phono 1 seems to have a few different components when compared to the version I have (not that old, purchased in 2018).

Aside from the Vishay Caps and Toroidy transformer has anything else changed; op amps, resistors...?

Thanks in advance ,

Regards

Mark

Vishay caps and Toroidy transformer aside, we upgraded all resistors to Vishay. We listened to other op amps but found that the original ones still sound best.

Thanks for replying so quickly.

Sounds like a case of well thought-out refinement.

I think there are aspects of my setup that require more immediate attention but curiosity got the better of me.
