Jeff Rowlands Amp and Dac vs. VAC amp and DAC

Excellent advice. I will look into them. Thanks!!! A good place to start. 

Cables are about system synergy...no such animal as the best. I have an all Jeff Rowland system driving Monitor Audio PL500's and I use Wireworld Platinum interconnect and power cables. I use Wireworld Silver Eclipse 7 speaker cable. There are too many possible combinations, so try a couple and choose what sounds best to your ears.

rinpoche,

Was curious if you knew which ICs were used during your audition from the vantage point of if you liked the sound it might be a consideration for you without others' preference bias (including mine).  Just a thought. 

Yes, Mogami cables. One of the reasons why the recordings are of poor quality. They are okay at best nothing more. You don't want this stuff for Rowland and VAC. DiMarzio is better, I still keep the RCA pair, but I don't think he makes them any longer. For serious comparison I would try Purist, High Fidelity, Stealth, Jorma, Tara, Wireworld. They might all give an excellent but somewhat different sound. Then it will be a matter of taste.

Rinpoche,
I have an unusual suggestion.
I suspect that you have a good hearing.
Go to www.mundo-flamenco.com ; it is a place that sells good acoustic guitars. Click on the 'guitars' and listen to the guitars that are not for sale. It's MP3 but you can hear the difference quite clearly. If you like more the guitar by Antonio Marin Montero - you probably want VAC amp, if the one by Conde - probably Rowland. They are both great guitars.
