Jeff Rowlands Amp and Dac vs. VAC amp and DAC

Hi Rinpoche,

Regarding the interconnects that would be used at the output of the Aeris DAC, I note the following statement in the Aeris’ description:

Transformer balanced XLR line outputs provide outstanding output common-mode noise rejection, eliminate potential ground loops, and ensure compatibility with other equipment.

I also note that it has a 120 ohm output impedance, which although not especially low is considerably lower than in many other designs.

I suspect that those factors will result in that DAC having somewhat less sensitivity to cable differences (at its balanced analog outputs) than would be the case in many other circumstances. Especially if the length that is necessary is only 1 meter, as most analog cable effects are proportional to length.

Okay, I listened to both guitarists. And, here is the thing, I liked them both! Yes, at first I was drawn to Conde, but on second hearing I felt equally involved in Montero. In a way, an ideal test would be if they played the same piece. I see the differences you are getting at. Softer and warm on one hand, or crisper yet musical on the other hand. Very interesting test. Thank you. 

As for the interconnect cables, it just looked like a good deal. I am sure my dealer will also have suggestions. If I could find something good that is used I would save some a bit of money. I will use balanced XLR for sure. I don't think I need more than 1 meter.

I have a colleague who swears by a cable made locally that costs $45.00. He has tried many cables and goes back to this one regularly. He said it might be a great place to start? 

rinpoche not sure what your system configuration is now or how you were listening to music before or if your going to need balanced or single ended cables. All that being said given the fact that you have Crystal speaker cables this looked interesting:

Same brand so hopefully some synergy there, affordable at $275 used and the seller is in Canada. I don't know the seller but plenty of positive feedback and buying affordable used cable is typically an easy and very low risk proposition.

Thank you jond for looking and sending that listing. My cables are Standard Diamond series which is a bit higher up than the Micro (and thus more costly). If you think that there is synergy in having the same interconnect as speaker cable, I could look around and see what is out there. But, if I am going to change speaker cable down the road, do you think it might be better to start with a different interconnect and work from there? Since with the interconnects I am starting from scratch? Maybe there is a CC Diamond interconnect for sale. It is a bright and lively cable. I did hear it against Nordost, which sounded heavier and darker, if that makes any sense. But I have not heard any other cables. In my 'old' system I had AudioQuest cables (that looked a lot like garden hoses). 

What do you think?

If you think that there is synergy in having the same interconnect as speaker cable, I could look around and see what is out there.

Opinions are divided on that question, which involves what is often referred to as "loom theory."  For example, see the following threads:

https://forum.audiogon.com/discussions/what-about-loom-theory

https://forum.audiogon.com/discussions/power-cord-brands-mixing-quot-your-opinions-quot

(The second thread initially focused just on power cords, but eventually broadened in scope to address all cables).

As you'll see, I happen to be one of those who do not subscribe to that theory, for the reasons I stated in the threads.

Best,
