Preamp headphone amplifier


I just purchased a set of Sennheiser HD650 headphones and to start will be driving them with my Mark Levinson no.526 preamp built in headphone amplifier.  Does anyone have experience with this or similar headphone amp and is it a good headphone amp or should I look into a dedicated headphone amp?

Thank you.

@soix + 1 - and even if the built-in one is not 'really bad', it would likely still be noticeably inferior to a relatively inexpensive but good separate headphone amp, so I would suggest looking into one. 

So I received my Sennhieser HD650 headphones and man they sound fantastic just after a couple hours playing. Using the built in headphone amp in my Mark Levinson no.526 preamp and its no slouch. Needs a bit more power but very good and the heaphones aren’t even broke in yet. I have a dedicated Feliks Audio Echo MkII tube headphone amp on the way, i cant wait! I hear it pairs will with the Sennhiesers and is a great amp. 

I glanced over the specs on your ML pre and it looks like the headphone section is fairly well designed so it’s not surprising that you’re getting good results.

Hope you enjoy the tube amp. I’ve also found Donald North’s designs to be truly exceptional - link.
