I can only share my point of view and my system. After hearing the Merason, I knew the P-II was lacking the emotion in music especially the vocal. I was about to sell the P-II. Then the update firmware came along. It’s free of cost so I gave it a try. And the rest is history. I am sticking with Denafrips. The new update is not only improving the tonal balance and articulation, but also improve on soundstage and transparency.
After I read
liangx5’s post: "I have seen enough positive responses not to be tempted to give it a try. The bad news for me is that my T-Plus is the last one in line to get updated, the good news is that hopefully by then they would have already learned and come up with a better/improved firmware :) "
I went back to watch Steve Huff’s "T-Plus 12" and Hans Beekhuyzen’s "T-Plus" reviews again. The way Mr. Beekhuyzen described the sq of T-Plus was like he was describing my post updated P-II. However, he did also contribute to the improvement to his latest new amp. As for now, I am waiting to hear the comments of updated T-Plus. I would be likely to replace the P-II and Chord with the updated T-Plus 12.
So, my conclusion is it all depends on both of whether your system could take advantage of the update or not and your personal preference. :)
Note: I have had the P-II for more than a year and It improved the area that was important to me right after the update. And it would be nice that it will sound even better later on. :)
