My go to headphones at the moment are the Audeze LCD1 and spatially, they really separate the instruments in the soundstage. However, on a hunch, I've pulled out my beloved Sennheiser HD580s to listen to the Vegh LvB SQs. While they don't go as deep in the lower end as the LCD1s there is a wealth of tone and timbre that imparts something to the music that I haven't heard before. Like with the Audeze's, the instruments are sitting in their own space and there is a sense of liquidity that really makes this glorious music. I'm listening to Op 130 at the moment and will move on to Op 132. I might make the 580s my SQ listening cans.
Something tells me I should start listening to these via my HiFi set up.
