great headphone amplification in vintage gear?

Thank you for all responses, the Revox looks pretty sweet!

Any of the old NAD 7100 series receivers have a really good headphone amp in them.

Old Fisher 400 tube receiver. Headphone output is terrific!

I too have a MH25 and am want for something better. I recently auditioned the Luxman SQ-38u integrated and it was hands down the best "headphone" amp I've ever heard. Even though it didn't work with my speakers (ProAc) I was tempted to buy it anyway to pair with my AKg 702's and change speakers. Alas, the $6,000 price tag dashed those thoughts.

I think the key is that Luxman are Class A amps for the most part (not sure of your L480, but seems likely) where the Music Hall is A/B. I was going to start a similar thread looking for Class A HPAs, but your idea of just looking for a vintage integrated might be the ticket.

If you pick something up, let me know - I'll be curious of your thoughts.

Hi, I realize that this is an older thread but I am going to purchase a pair of audio technica m50x headphones this weekend as my first venture into headphones. My question is that while I continue to get a feel for headphone amps and additional cans, can I safely use a Yamaha CR820 receiver in the meantime? Any potential issues to be considered. And hopefully not a totally dumb question, do I have to have a set of speakers hooked up to avoid damaging the receiver? Thanks much, and Happy 4th to all!! Thanks, Dave
