Jeff Rowlands Amp and Dac vs. VAC amp and DAC

Here's a thought, maybe do as I do...
own a Rowland ss amp for when you want that ss sound..and a tube amp for when you like the sound of tubes!
The Rowland is an excellent ss amp, having said that, it has all of the typical ss attributes...less depth than what tubes will give you, less purity in the midrange and slightly less definition of timbre. OTOH, the ss amp has better control of the bass, slightly more exact positioning of the players on the stage...although as I said above, the stage is foreshortened and the bonus of being a) probably more reliable and b) giving off less heat. Plus, the ss amp can typically drive a wider range of speakers ( at least the one I own). 
There is no amp that I am aware of that gives the best of both worlds...ss and tube.

ricred1..don't get your pan..... in a twist!
I own a customized ( by Jeff) model 8T...which frankly blew away the standard 625 in my system when I did an AB. My tube amp ( which I suspect you do not own--or for that matter any tube amp!) is an ARC classic. Like all great tube amps, it has a sound that no ss amp can achieve....none.  Sure, the Rowlands create depth, just not IME as much depth as the best tube amps of my experience. Unfortunately, I suspect that you have not heard what a great tube amp can do in your system...
That's not my problem.
Like I said before---no wrongs, no rights. Ok, next---

ricred1, i have not heard the 625S2 in my system, but I have heard the
625's on several occasions. The 625's are a good amp, but like I said, they sound to me like a ss amp ( nothing really wrong in that). The ss sound is ( at least to my ears) not quite the same "flavor" as the tube sound. No wrongs, no rights.
