Esoteric F03a vs Pass Labs INT-60 vs VAC Sigma 170i - Discuss


Hi all - anyone every owned or had listening time with Esoteric F03a and Pass Labs INT-60? I think its an interesting comparison given the 30 watts of class A power in both. On top of that lets throw in a tube integrated with some power such as a VAC Sigma 170i. Would be driving 93+ sensitivity speakers. Thoughts on which is best? Most musical? etc.

 I’ve never heard the esoteric but I have owned the pass 60 and it is tube like I its presentation. Midrange vocals to die for. I have moved up to the pass 250 which is a more neutral sounding. The 60 is warm sounding, and some like its presentation better than the 250. The 60 does run warm,  it’s nice in winter and a none issue if you got the ac on.

Which one did you end up choosing and how are you enjoying it? I am also torn between the Pass Labs Int 60 and the Esoteric F-03A as I can get them both for the same price. Thanks

We have experience with the Esoteric and Vac products

 

the vac is definitely the most musical, nothing beats a tube amplifier for tone and soundstage

the esoteric provides stunning detail yet s not bright build quality is amazing

the pass stuff runs too hot and is a bit rolled off in the top end for us

 

hope this helps
