Thank you, and thank you for the detailed reply! That's a relief to hear.
It's just one of those audio nervosa things that I've heard for awhile now.. the less you can have in the signal path, the better (generally). 😛
Audiophiles like to talk about how preamps and DACs effect many different sonic aspects such as soundstage, timbre, texture, and other hyperbolic phrases. And, I've noticed differences when comparing passive vs tube vs solid state preamps.
Right now I use a pi2AES --> AES --> Schiit Yggy --> Pioneer Exclusive C3 Preamp. It just makes me wonder if, down the road with the Jubilees, it'd make more sense to essentially use the DSP unit as both a DAC & preamp to remove redundancies? It seems like there'd probably be little to nothing lost in doing so, and I could totally see this become more mainstream in HiFi... hmmm. 🤔
Regarding balanced to the amplifiers -- I have a 300B SET, Pioneer M22& M4 (Class A), and am considering building one of Nelson's DIY VFET designs down the road. All of these are single ended. I don't notice any noise from the power amp when running them through Heresy's, but 105 db/2.83V is definitely a lot more sensitive lol. I do notice very slight noise from my preamp if I get within a foot or so of the speaker, so that could be an issue with the Jubilees. 😕
It'd be another year or so before I make a move up to them, but it's always nice to try and consider what an upgrade path would look like ahead of time.
Thanks again for the tips!
