OK I've been a big fan of the HD650 sice I got into this hobby a couple of years ago but up until tonight I have never heard them to their full potential, I have driven them with a Benchmark DAC 1, Violectric V100, Matrix M stage, Schiit Valhalla and some cmoys but I find now that where I thought they were performing well - nothing has prepared me for the sound that is now coming from the Woo WA6 with Sophia Princess upgrade. I have had the Woo for a while and thought yeah its ok but bought a Sophia Princess Rectifier today and am being totally floored by what I am hearing - so natural, open, wide, dynamic, I could go on but I wont
This is synergy at its finest and the tube hasnt even burnt in yet - only 4 hrs on the clock. No upgrade has made as much difference to my system , if you have a WA6 you owe it to yourself to get the Sophia. Now if I had only kept hold of my Grados I am itching to hear how they would've sounded like with this combo but I can't imagine I would be missing much as this combo sounds amazing. I have an equinox cable on its way so I'll report back with my findings on that tweak when it arrives.
