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?

Rinpoche,
Absolutely logical explanation and response. It isn’t "always" necessary to take baby steps. Your Wilson and Rowland system have you perched at a pretty high level in the realm of High End Audio . Finding a highly regarded cable (that’s needed to complete your system connection ) for a very attractive price makes nothing but good sense. The Mogambi suggestion was made in part to satisfy my selfish curiosity. You have good ears and I would have been interested in your listening comparison.

Maybe one day Charles1dad!
I am finding that transcendental moment even with the Transparent loaner cable. I think the AQ is going to be amazing. I really do. But I will let you know next week when it arrives and settles in.

Rinpoche, 
It's funny how we choose to listen to the advice that suits our needs. I understand what Guido said about the 625 and Aeris DAC, but he doesn't have the 625 S2 with his Aeris DAC...I do. I'll be the first to say, it's only my opinion,  in my system,  but there is a significant difference between the 625 S2/ Aeris DAC and the same combination with the Corus. In my system, with my ears, it isn't close. ..more dynamic, air, and just a sense of ease with the Corus.

Hi Ricred1,
This is one of the classic timeless High End  audio debates, active preamplifier versus direct source to power amplifier. I consistently find I prefer the inclusion of the active preamplifier, personal taste and nothing more. I do believe that Rinpoche is hearing excellent sound with her current direct set up, it’d be quite interesting to see her impressions if given the opportunity to insert the Corus or other high quality preamplifier into her fine system. You never know until you’ve experienced both approaches.

Hi Richard, to be more precise, my experience has been with Criterion rather than Corus. I have applied it to M312, M625, M725, and my current M925 monos over sevral years. While I am incredibly happy about driving my system without preamplifier, I do recognize that some might prefer Corus in the chain.


I might give Corus a try actually, as Rowland will be releasing the external 3-outputs power supply based on ultracapacitors, called PSU. PSU can power up to three compatible devices with DC power 24/7... Currntly, it is compatible with Aeris and Corus... Yes, both connected at the same time. People who have tested said its effect is transformative. Eventually, I hope to verify this on my own system... I would not be surprised if I fell in love with Corus all over again.
