Jeff Rowlands Amp and Dac vs. VAC amp and DAC

rinpoche,
I which I could say something to reassure that you're going to be happy with Jeff Rowland, but I can't. Components are very personal, so you never know. In my system the 625 S2 is by far the most musical amp I've ever had.  After 30 years in this hobby that's the best compliment that I can give. Unfortunately,  it doesn't mean you will feel the same. Best of luck to you. 

I will let you know. I am looking forward to finding out. THANKS

Rinpoche,
I am writing down my prediction as follows :- SWCRABVHWI.
Let's see what happens.  Good luck!

Hi Ricred1,
In some systems to certain listeners  the Gryphon will be preferred to the Rowland.  Change the listeners and or the system and suddenly the Rowland is deemed the superior amplifier. In the realm of upper tier transistor power amplifiers both stand tall. If I've learned one thing about audio system assembly it is that synergy is a real and major factor. 
Charles, 

Total system synergy also includes the way the system interacts with the environment it is in.
Place 2 identical sytems in 2 different rooms and both will sound different.
Place 2 identical systems in the same room but with different environments, like with one having a television in between the speakers, and again, both will sound different.

A system can sound only as good as the environment it is in.
