Jeff Rowlands Amp and Dac vs. VAC amp and DAC


Hello, I am new to this forum but I have a question. I am trying to pair an amp + DAC with my Wilson Sabrinas. I have listened to Jeff Rowlands integrated with the Aeris DAC. And the VAC Sigma integrated with the Aeris DAC. Price is a factor and so is space. Does the 625 need a pre-amp? Any suggestions or thoughts?

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---
Rinpoche, of course that's okay. Your original Rowland/VAC choice was an excellent move.
Who can afford Dior? Well, Dior jeans are about $550 and up, Diesel are about $200 or more. Is the difference big? It depends, but generally speaking not too big. Chanel is a different story - really expensive.

Chanel is classicism par excellance. Dior is 'new look' created in 50s. Both can be great, also depends on the occasion. But if choosing just one, yeah, Chanel wins.
