I think the crossfeed in Marley Mkii is much better than that found in the Ican pro signature I had
It does a great job with Composer, but in order to have that beautiful holographic soundstage it simply isn't necessary with the Marley.
The Marley to me sounds like taking the transparency of the Bryson bha-1 and increasing it but with the beautiful timber of Burson except the imaging is a level above the Bryston.
It's unfortunate it never gained traction in the U.S as it's simply the best amp I've ever heard.
It even drives Susvara beautifully 5wats into 60ohms all the while being a tiny amp which makes it even better and more amazing because I can throw it in a bag if I travel
Or in my case, I'll just take the Young Mkiv and a wall wart, as the headphone out of that dac is better than the old 3xp I had (it's what made me finally pull the trigger on the Marley) and it, like the Marley is the same small size as the Burson 3xp.
Which is one reason I loved the 3xp stacked with the Young Mkiv as they were the same small space saving size, but the Marley is a whole new universe compared to 3xp.
The ability to change output impedance is fun to play with as it opens doors to all different types of drivers, in my case, if it didn't have the ability to change, I couldn't use my MySphere because at 0" it had terrible feedback due to the drivers in the MySphere, but changing the output impedance to 10 ohm set it up perfectly and sings in such a beautiful way. As a reviewer said and that resonates with me the same when he said " I love it to my bones"
If you are ever interested in one pm me.
