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?

I have heard the vac integrated at length and it is a great amp. I also prefer tubes over ss for the Wilsons

I hope you will indulge me a bit here. I have heard the VAC Sigma 160iSE and the JR 625 upgrade both with the Aeris as the DAC. I am a bit nervous about tubes. This would be my first time with a tube amp. I do agree that the VAC is amazing. The JR is also good and it is a bit easier given it is plug and play and no tweaking, changing tubes, etc. is required -- so are tubes really difficult? Is the sound worth it? I agree that the VAC is fabulous but the JR is also very nice. Please say more on the topic if you can? 
You said it yourself. If you want fabulous get the Vac. If you want very nice get the Rowland. Vac amps are pretty much plug and play

Thank you for saying that. I really appreciate the advice and experience of this forum. Yes, I have been told that the VAC will plug and play and then, of course, need servicing, but I also want to use it to watch/listen to films and even TV. That means, the tubes will be on more often than if I only used it for listening to music. Do any of you use a tube amp for film and TV?
