OTL vs regular SETs for high-impedance headphones (eg: HD650s)

post #1 of 3
Thread Starter 

While I realize this is to some extent dependent on the actual amp design, is there some specific general benefit to going OTL when pairing with a high-impedance headphone like the HD650?

 

I am looking to have 2-can endgame system:  a HD650 and a LCD-2.  

 

I know an OTL 6SN7 design is often recommended as the best pairing for the HD650 - I am wondering how much I'll give up if I get a regular transformer-output SET to drive both the headphones, vs having separate amps for each (which I can do if need be, although obviously I'd prefer just one amp vs two).

 

Thanks!

If you DIY, I'd highly recommend the BH SEX. I have an HD600 and an LCD2, they pair very well with the SEX. It can power sensitive speakers too.

I actually do DIY, but I want a better-looking amp than a home-brewed unit.   And am trying to decide between 2 separate amps (an OTL for the 650 and a regular SET for the LCD-2), or One Amp to Drive Them All.

 

Hence trying to figure out what's what.   Sadly, no amps for sale within 1000km of me, so that makes try-before-you-buy a little iffy.
