For those of you who don't know, the valve sits right in the DAC stage - It's actually a regular SSD amp, with a tube DAC.
I was about to pull the trigger on a big, expensive, shiny valve headphone amplifier to go with it, but just before I did, my ever so thoughtful (and luckily, wallet-concious) girlfriend asked me:
I replied "A tube amp, for my headphones"
Girlfriend: "Haven't you already got one?"
Me: "Well yeah, It has tubes, but then it's a regular amplifier after that."
Girlfriend: "But you have tube sound already. What's the benefit in more tubes?"
And then I stopped in my tracks, and realised I didn't have anything to reply with. Clever girl.
It made me think, even if the signal chain was this:
Computer -> USB -> Aune T1 tube DAC -> Line out -> Receiver -> Speakers,
Isn't the receiver technically then getting "Tube sound"?
TL;DR: What would be the benefit of getting a valve amplifier of any kind, when one can use the Line out of the AUNE T1 to give "Tube flavour" to any amplifier?
