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 am so fortunate to hear from all of you. Really. I mean that seriously. Not only are you all so knowledgeable, you are also giving and helpful....and funny (see jon2020). Okay, so maybe I am in denial. But I hear that cables are important! No? 

And, inna, you are so right. I am torn. Solid state is easier and I am anticipating that tubes might be more fiddly (also I need it for TV and film). But maybe worth it! So, good idea to suggest a hybrid. In fact, that is why I went to hear the (demo) PS Audio amp. The LAMM/Kharma/Purist Audio could be my stereo goal — for my retirement (or with my retirement fund?). 

I am happy though that you all seem to like JR and VAC. Really. I don't want to make a mistake at these prices. It certainly won't be top of the line VAC — they are out of reach, or JR top of the line. But the 200 IQ is affordable. And who knows the Rowland might just win out in the end — we will see. Let me first hear the VAC (an early suggestion on this thread).

I am also really getting very excited to see how this turns out. What will be the first thing I play on it? Now that is a thread we should work on. What is the first song you play on your new stereo? You folks are fabulous. I mean that. 
What are break-in test tones? 
Are you saying after the first 1500 hours if its the JR? Cuz I can't wait that long!!!!!

What will be the first thing I play on it? Now that is a thread we should work on. What is the first song you play on your new stereo?
If classical music is of interest, try Dvorak's "New World Symphony," Jascha Horenstein conducting the Royal Philharmonic Orchestra, Chesky CD31.  Out of print, but available from various sellers at Amazon:

And if classical music is not presently of interest, it very well may be after you hear this recording, which you will not believe was recorded in 1962!

Rinpoche,
I'd play recordings that you both enjoy and are pretty familiar with. You're use to how they sound in your system and thus will easily detect any differences in presentation provided by a new component. This approach has been very effective for me through the years. We all here are interested to read your listening experiences with the select group of amplifiers.  This is an enjoyable thread.
