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?

knghifi,

Those are some good points.  I have a VAC Ren Sig II that is a very nice sounding tubed preamp that plays happily with any amplifier setup, and I have tried SS amps, but I always come back to tube amps.  They just bring me closer to the palpable sense I get at live music events, and as much as I would like the convenience of SS, it doesn't do the same for me.  Of course, I haven't tried anything close to all of the SS contenders, but I'm too happy with my tubes right now for that.  It all gets down to our personal reactions as to what is sonically important, and there is no accounting for that - - we like what we like.

Interesting that your TAD E1's are not too fussy in placement.  I was captivated by those at the Zesto Audio demo at RMAF 2014, and that is what got me investigating the TAD line and eventually ending up with the CR-1's.  The E1's are a great speaker.  I find the CR-1's to be quite dependent upon placement for issues of imaging and for harmonic fill in the upper bass, lower midrange, so they seem to be less forgiving - - kind of their reputation!  But when you do get them right, boy, do they sing so sweetly and so true!

I'm curious, what amp are you driving your E1's with?
Knghifi,
I agree with you in that there are numerous very good choices available. I'm curious to read how the VAC iq matches with the Sabrinas.  Many roads led to Rome. 
Charles, 
Of course one can build a system around any particular component that uniquely floats their boat.    If it turns out to be the VAC amp, a very enticing piece, and the results with the Wilson's are not suitable, you could easily elect to sell the Wilson's and go with speakers better suited to enable the VAC to shine its best.

Many roads indeed but not all are created equal.
jbrrp1,

I also have a VAC SigMKIIa pre and just had it upgraded to SE several months ago.   Kevin offers an upgrade every decade and I STRONLY recommend it.   A No Brainer!

I'm driving the TAD E1 with ARC Ref250SE and Hegel H30.   H30 in the summer and backup.  
Rinpoche, what other loudspeakers did you listen to when you picked the Sabrinas?
