Re: Differential Headphone Amplifier schematic

I have heard Kevin's differential headphone amp and I think it's quite good. This is truly the best I have heard from an amp of this type, including solid state designs. No opamps for my headphones, please. My single ended (6SN7 directly coupled to 2A3's with Lundahl output transformers) is a different sound altogether. The tonal differences are not that great but in terms of presentation, the PP design has dynamics to die for. The leading transients are taut and fully integrated with the pace and flow of the music. The transistorized heaphone preamps I have spent time with seem to strip harmonics and trailing transients out leaving a more threadbare sound. Some people call this cleanliness or accurate but if it doesn't sound like music than it's wrong. You're missing something but not with this little differential amp. It's a mastering editor's dream tool. You don't miss a thing and at the same time the sound is capitivatingly real. The music seems to be to cut from whole cloth. There is a seamless quality to the sound. All the room sound is preserved and on good recordings I just want to hear more. I told Kevin not to leave me alone with his headphone amp because he may never see it again. Jokes aside, this is my next K&K Audio project. Good luck to you.
