Thanks for your voice message Paul. I was in meetings all day and will call you tomorrow. To answer your questions, the Solaris is a dream I have had for the past 6 years. I first reached out to Audio Note about some custom 2A3 headphone transformers back in July 2009. They are very busy but after 6 years of patience and persistence, they finally developed a custom pair of output transformers to my specification. I received them earlier this summer and they sound fantastic. They have the musicality of those in the Stratus together with greater resolution, clarity, layering, dynamics, and bass slam. Because of their capabilities I have been revisiting all of the other components to match their sound quality and resolution. For the coupling capacitors, yes I plan to use the Duelund CAST copper foils. I prefer the sound of top coupling capacitors to non-nickel & silver, unshielded interstage transformers. This amplifier will also feature balanced XLR inputs and I just received notice today that my balanced input transformer samples shipped today from Audio Note. I want to use the best sounding components to me. This will be a regular model to be released in early 2016.
