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?

Hello,
I went to hear the VAC 200 iq system today. It is very beautiful. I think you would all agree it is engaging and warm and in a word gorgeous. However, I also listened to the JR with a tube preamp and I must say it was even better. So, I think the way to go is the Rowland for now and add a preamp when I can afford it down the road. The preamp with the Rowland completed the circle. It gave me a VAC sound with the ease of solid state. I think this is going to work out just fine. Your help and advice and suggestions have been fabulous. Oh, by the way, I recommend a piece for you to play. It is called Prayer Cycle and the track is called Benediction with Linda Rondstadt and Nusreh Fateh Ali Khan. The words are 'made up'. Not a real language, and it sounded so so beautiful today all three times I listened to it, but the fullest was the JR and tube preamp (ARC). So so so nice. I think I am almost at the finish line -- for now (LOL). R
I was quite certain you would choose Rowland. Fine tuning with tube preamp is next possible step. In any event, tube preamp/transistor power amp set-up is favoured by many. Especially with digital source. Purist audiophiles would never do this, though, but to hell with them.
To start - I am not one of them. I choose whatever combination I like. Purist would do either full tube or full solid state, more often full tube.
