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?

Yeah, why not try Mogami too, it costs nothing? However, pro-audio and audiophile audio are not the same things. One of the differences is that they would try to save every cent to increase the profit, we would not. I tried DiMarzio cables, something very popular with musicians as guitar amp cable. Yngwie Malmsteen comes to mind. Good cable, no match for Purist. I did try RCA though.
Okay, so my dealer just emailed to say that I have to return the loaner to the shop. Now I need to really decide. I will figure something out. Does anyone know anything about Siltech 770i (Or some such number)? There is a used pair for sale. And/or I can get the same Crystal Cable at a not too too bad price for sale. Or, buy something -- dare I say it, new?


rinpoche,  if you need 1 meter length and want to buy yourself time to look around and decide upon what you really want without having to rush into a purchase I have an extra pair of unused balanced Silnote Audio Morpheous ICs that you can have and be yours to keep at no cost to you. If you're interested in my offer send me a message as I'd be happy to help you out; if not no problem. 
Facten,
That's such a nice offfer. There are good people on this site.
