upgrade is back

[Confused]

Could someone here make a case for upgrading a 120 other than "preserving resale value?"  My 120 (with the sub output) sounds great and works great with Roon for streaming.  Other than a bit more power, what does another three grand buy me in terms of sound quality and/or improved functionality? 

Are there any reviews out there suggesting the new models are an important step forward in sound quality?

Thanks

Not that impressive - these read like comment threads on firmware updates, not a hardware update that costs almost half the price of a new unit.  Can anyone else shed any light or point to "professional" reviews of the Expert Pro?  Thanks.

There are few "professional" Pro reviews that have been posted here:

And I recall this one specifically for the 130 Pro

To be honest, I do not think there have been many professional / published reviews that compare the Pro to the Expert.  Also, you need to know which reviewers to trust, some are a little biased in line with whoever pays the most for advertising.  Personally, I'd love to see reviews in magazines where the golden ears magazine reviewers are doing comparative reviews in controlled blind conditions.  It will never happen though.
