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?

Congratulations and happy birthday from me as well, Rinpoche.  I have no doubt that your choice will prove to be a source of delight for a great many years to come.

That's good, you settled it.
Don't be so sure - you may not like our faces.
Hear from you next year, about the preamp, if you feel you need it.
There is an old Gryphon preamp here right now. I wonder, how would it work with your Rowland? No, it's not a suggestion and frankly I have no idea how and if it would work.
Have any of you people ever tried this or similar combination?
