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?

YOU HAVE DONE MORE THAN YOUR BEST. YOU HAVE 'ALL' BEEN AMAZING. I HOPE TO HEAR THE VAC 200 THIS WEEKEND. AND I WILL LET YOU KNOW HOW IT SOUNDS. I CAN'T WAIT. AS JON2020 SAID, 'A MONTH AND NO AMP, NO INTERCONNECTS, NO MUSIC AND NO INSPIRATION' LOL.

YOU ARE SUCH AN AMAZING COMMUNITY OF KNOWLEDGE AND MUSICAL INTELLIGENCE. THANK YOU ALL FOR YOUR THOUGHTFUL AND KIND ASSISTANCE. I HAVE LEARNED SO SO MUCH. APPRECIATIVELY, R
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.
