I leave it on H now (for VC anyway) so that's 600 into 300 I guess. I suppose technically its not optimal to have output impedance higher than input impedance (or is that different depending on whether that is power or voltage transfer - I dunno, long time since I did this stuff) but it sounds...

Sound and Vision - Bowie

Over the Mountain - Ozzy Osbourne

I know what you mean, I can only dream what this kit sounds like off really high end sources now. I curse the day I ventured beyond my HD600 and Magni/Modi which sustained me for years.

Lips in the Hills - Blue Oyster Cult

Some of those instant likes fall away but all these blew me away on first listen and have never worn off... 2112 - Rush Boys Dont Cry - The Cure Valentines Day - Bowie Gimme shelter - Stones Sultans of Swing - Dire Straits Electricity - Beefheart Achilles Last Stand - Led Zep Cliffs of Dover -...

Another Hit and Run - Def Leppard

...was listening to the headphones and not the music any more. Sadface. Amp and dac upgrade (went from delta sigma to R2R and better tube amp) and....screw me. It all gelled. I'm blown away. Conclusion - some 'late to the party' random hi-fi noob realizes sources actually can matter a great deal...

I tried the preset on there for my VC and I would call that particular target curve 'make your expensive headphones sound like they came free in a Christmas cracker'
